Cassandra Truth

    Everything About Fiction You Never Wanted to Know.

    A prophet that, Cassandra-like,
    Tells truth without belief...

    Anonymous, "Advice to a Lover", 17th or 18th century English poem

    Sometimes people just won't believe you.

    You try your hardest to tell someone that your parents are actually super villains and that you need their help to bring them down, or that aliens have landed in your backyard and are now plundering your kitchen, or that the nice grandpa in the flat above you is in fact an evil bloodthirsty creature from another dimension, but the authorities look at you like you are crazy and send you packing. What's a lone protagonist to do?

    A common staple of Disney and children's films, where the Kid Hero stumbles upon an evil conspiracy or a criminal ring and their parents and the police refuse to listen. The only thing to do is to save the day yourself, with PG heroics and Scooby Doo style.

    If the protagonist trying to report the situation works for someone who can actually do something about it, such as the FBI, it's not so much that s/he isn't believed, but Da Chief will tell him/her that it isn't worth it to expend resources "on a hunch".

    This sort of situation can also be used to maintain the Masquerade: if a minor character finds out and tries to tell someone that the guy next door is secretly a Warrior of Justice, they won't be believed, because who would ever think that that foppish playboy could really be the dark, grim Superhero? Often though, it's because they're horrible at wording it so it sounds genuinely insane.

    Sometimes Character A actually asks what's going on and, when given the true-but-bizarre explanation by Character B, responds "Well, if you don't want to tell me, just say so".

    Related to Devil in Plain Sight, except that in that case, the disbelief is mainly due to the deceptive abilities of the "devil", whereas in this one, it's usually due to strange circumstances, the perceived unreliability of the speaker, or just plain bad luck. It can also be a Crying Wolf situation, where the fact that the character lied previously is obfuscating the fact that they're telling the truth now. If it deals with uncovering something that might be dangerous and people don't believe the person not because they think they are lying but because they are crazy, see Properly Paranoid.

    The title comes from the mythical seer Cassandra, whose prophecies were always accurate but never believed due to a curse from the god Apollo, thus making this Older Than Feudalism. (Writers of speculative fiction just looove to name precognitive or clairvoyant characters "Cassandra" or some variant thereof. Yeah, Smallville, Buffy the Vampire Slayer, Red Dwarf, and The X-Files—we're lookin' at you.)

    If the person telling the truth is an NPC in a video game, they're spouting Infallible Babble. In this case, the in-game characters won't believe them, but a Genre Savvy player will.

    If the character is the one guy to figure something out despite all the much more expert people working on the problem, he is an Einstein Sue.

    This is often played to ridicule the doubters, even when the truth is on the level of the absurd. A protagonist warns others of a completely unlikely, nigh impossible event, but the audience, in on the secret, perceives a truth they would normally doubt themselves as completely obvious.

    Subtropes are Ignored Expert and The Cassandra, where the character in question is in a position where they really should be believed, due to authority on the subject or track record of accuracy, but still isn't.

    See also Not-So-Imaginary Friend, for a specific situation where the "truth" is the existence of a character. If the person telling the truth is dismissed by law enforcement officers, it's Police Are Useless. When the truth in question has something to do with Medium Awareness, compare Audience? What Audience?.

    Contrast with Sarcastic Confession and You Wouldn't Believe Me If I Told You, or The Inner Reveal when they believe the truth. A particularly cynical twist is when whoever wasn't listening concludes that Cassandra Did It when what she's saying comes true.

    The Other Wiki even has an article about Cassandra Truth.

    Examples of Cassandra Truth include:

    Anime and Manga

    • Pretty much any hero in the .hack franchise can't even get to telling their parents or the authorities; despite mass server failures, clear evidence of a conspiracy or two, people trapped in the game, machine problems everywhere and even comas, who would believe that an MMORPG was Serious Business?
    • Kid-Conan in the Detective Conan series knows about this problem, and solves it using a tranquilizer watch and a voice-changing bowtie to make it seem like someone more trustworthy in the eyes of the police is making all the deductions.
    • In Haruhi Suzumiya, Kyon tells Haruhi about Itsuki, Yuki, and Mikuru's supernatural powers, and she flat-out doesn't believe him and tells him to stop messing with her. Then she makes the movie The Adventures of Mikuru Asahina Episode 00. It was not a coincidence, guys.
    • Happened early in One Piece, during the arc that introduced Ussop. In the aforementioned arc the villain ended up being well known in Ussop's town, and being a known liar, no one believed him.
      • Played for Laughs in the Fishman Island arc when Princess Shirahoshi is "kidnapped" and King Neptune believes Luffy did it. Brook comments he didn't see her leave, only seeing Luffy riding a shark (Megalo). Neptune believes he stuffed Shirahoshi into Megalo's mouth and rode out. The guards all laugh at this idea. ... That's exactly what happened.
    • Quent in Wolfs Rain repeatedly fails to convince people that wolves are adopting human disguise for sinister purposes. He's right about the disguises, but wrong about the wolves' motivation.
    • Poor Rika in Higurashi no Naku Koro ni. She tries to warn Tomitake and Takano, but do they ever listen to her? Of course not; she barely comes up to their bellybuttons. (Actually, at one point Takano does seem to acknowledge Rika's foresight, but that's only because she knows what's going to happen; it's her Evil Plan.)
    • Light Yagami of Death Note subverts this several times, at one point "admitting" that he might be Kira so he can be locked up in order to prove that he isn't Kira and renounces possession of the Death Note so he can lose his memory, thus playing the role of innocent even more. Of course, it is all All According To Keikaku.[1]
    • In Full Metal Panic!, when Sōsuke explains to Kaname that he's a soldier from an elite military unit on orders to protect her, Kaname informs him that he's delusional—even as he's fighting off enemy soldiers and escaping with her across a military base. It's not until he climbs into an outdated Humongous Mecha and kicks a world of ass with it that she realizes he's telling the unvarnished truth.
    • In Mahou Sensei Negima, Negi Springfield (though it is admittedly his fault) makes a good attempt at warning the other mage teachers about the existence of a Time Machine which could be used to Set Right What Once Went Wrong. Somehow, even full-fledged mages refuses to accept the idea of time travel. Also, nobody believes Chao the first time she tells everybody she's in truth "an alien from Mars." And still... Truth be told, Negi himself had it coming since the other mage teachers tried to convince him that Chao was on the verge of causing serious problems and he didn't listen to them.
    • Bleach
      • After the Soul Society arc, Ichigo and company return to school. Contrast to Ichigo, Chad and Uryu who tell a series of Blatant Lies to explain their absence, Orihime tells the truth, not sparing a single detail. Everyone dismisses it because she's something of a Cloudcuckoolander.
      • When Ishida first appeared in Soul Society, Mayuri realised that Soul Society was vulnerable to quincy attack and, because Yamamoto had failed to kill an old enemy in the past, a quincy attack is precisely what was going to happen. Yamamoto dismissed Mayuri's advice as paranoia. Boy, did that decision come back to haunt the old man!
    • In Axis Powers Hetalia, England can see magical creatures while no one else can. Thus every other nation thinks he's gone insane when they find him talking to the air. In one strip, France, trying to get England for a meeting, walks in and sees a mob of fairies, unicorns and gnomes surrounding a sleeping England, and his reaction is hilarious.
    • Bardock, from Bardock: Father of Goku is given the power to see the future. However, he sees their planet being destroyed by Frieza. Naturally, no-one takes him seriously.
    • In Magical Girl Lyrical Nanoha, one of the known stories about the legendary lead character is how she became a AAA-Rank mage, solved her first Interdimensional Incident, and destroyed a Weapon of Mass Destruction said to be impossible to destroy at the age of nine. Non-fans like Teana, naturally, dismiss it.

    Teana: That just sounds like a rumor. What kind of nine year old was she?

    • Nobody believes that Akihisa Yoshii knows how to cook due to the fact that for those few episodes, we see him only eating sugar. Imagine everyone's surprise when he cooks paella.
    • Monster. Poor, poor Tenma. Try as he might, barely anyone will believe his story of a ten-year-old child committing serial murders.
    • Brutally subverted in Fullmetal Alchemist. When Mustang is looking for some allies in the military brass, he mentions a few "strange rumors" to General Raven, including Scar liking cats and Furher Bradley being a homunculus. Raven brushes it off as a bad joke from Mustang. Then immediately subverted when Raven leads Mustang into the meeting with all the top generals and ominously asks him to continue his "joke". Sometimes not being believed is not as bad as being believed by the WRONG people.
    • Code Geass
      • One of the most tragic examples comes when Lelouch, having just agreed with Euphie's terms behind the Special Administrative Zone, alludes to his power of Geass, but she doesn't believe him. He persists in giving more insidious possibilities of powers, until he just happens to be looking at her and says the wrong thing the moment Power Incontinence hits.
      • Also in season 2 episode 18 where Suzaku has a hard time warning Lelouch of the FLEIJA due to Schneizel having broken their friendship.
    • The creator of Gantz actually reveals the entire story of the Gantz operation to a reporter who confronts him for the truth. He then invokes this trope by saying that he told the entire truth because it's so outrageous that no-one would believe anyone who exposed the story.
    • In Natsume Yuujinchou, Natsume was typically regarded as an attention-seeking liar whenever he told people about the spirits and monsters only he could see.
    • In Satou Kashi no Dangan wa Uchinukenai, Nagisa doesn't believe her friend Umino when she tells her that her father killed her dog. Turns out she's not making this up for a change.
    • Puella Magi Madoka Magica has a tragic example in which Homura in the third time-loop tries to explain that Kyubey had been lying to the girls and has been orchestrated their transformations into witches. Not only does everyone not believe her, but when Sayaka finally does turn into a witch, the consequences lead to one of the worst events of all the loops.
    • Persona 4: The Animation has Yukiko and Rise telling Naoto all about the world inside the TV and Personas. Naoto doesn't believe them.
    • In Elfen Lied, Kouta's little sister Kanae risks her older brother's affections by insisting that she saw a horned girl kill people with arms that came out of her head at the Kamakura summer festival. Within about a minute of her saying this for the umpteenth time, Kouta is horribly made to learn that she wasn't lying.
    • Is It Wrong to Try to Pick Up Girls in a Dungeon?, season 2: nobody believes that Cassandra has prophetic dreams. They should have.

    Comic Books

    • The first volume of Runaways has the superpowered main characters struggling with the fact that no-one will believe that their parents are supervillains, resulting in them having to bring them down personally. Conversely, after the Pride are dead, their activities exposed, still few are willing to trust the Runaways, because of who their parents were. In this case it was somewhat subverted by the fact that the characters' parents essentially owned the police and had their fingers in the pies of every major organization, illicit or non, on the West Coast.
    • Tim Drake finds himself in this situation during "Red Robin" while he is trying to prove that Bruce Wayne is not dead.
    • In a Swamp Thing storyline where the title character is believed dead, Adam Strange shows up to tell Swampy's girlfriend that he's still alive and is trying to get home to her. She's incredibly relieved... until Adam starts helpfully explaining how he met him on an alien planet that he travels to by "zeta beam", at which point she shuts the door in his face.
    • John Byrne had fun with this during his run on Superman. A computer programmer working for Lex Luthor ran extensive data on both Superman and Clark Kent into the system, in order to find a perceived connection between them. When the computer responds, "Clark Kent Is Superman", Lex promptly fires the programmer, refusing to believe that someone with Superman's powers would be satisfied with a "normal" life.
    • In Route 666, the main character is named Cassandra (usually called "Cassie") and suddenly starts seeing a world of ghosts and horrific monsters preying upon humanity. No one else can see this, and so, in her struggles against them, she is also pursued by the police as a psychopathic killer.
    • Invoked by Neil Gaiman in a 1993 speech at the Diamond Retailers Seminar: "I'm not here to play Cassandra. I do not have the figure and I do not have the legs". In his speech, he predicted that the contemporary speculator boom in comics would result in the market crashing.
    • Jor-El in practically every version of Superman's origin. He knows Krypton is doomed, but nobody will listen.
    • The Teen Titans were founded due to a Cassandra Truth, the Cassandra here being Raven. She had initially approached the Justice League for helping in fighting her father Trigon, but they refused her on the advice of Zatanna, who sensed her demonic parentage. That led to plan-B, starting her own team - composed of herself, of Robin, Kid Flash, Wonder Girl, Starfire, Cyborg, and Beast Boy (then known as Changeling) - and the rest was history.

    Fan Works

    • This is the basic premise of The Boy Who Cried Yuri, with Shinji on the receiving end. When he tries to alert Misato, she instantly dismisses him—even though she should know very well that he's too much of a coward to make this up. Asuka even lampshades it.

    Rei: Asuka, do you think it is wise to do this now? Shinji may come in at any time.
    Asuka: No, Misato was talking to him. He's probably gotta go apologize to Fuyutsuki for screwing the test up.
    Rei: Do you think he suspects something?
    Asuka: I doubt it. Even if he does, people will think he's just fantasizing like he always does. The little pervert.
    (unknown to them, Shinji's already hiding in the room with a tape recorder)

    • In Kyon: Big Damn Hero, Kyon's sister had tried to tell her parents and friends that her brother is a hero and has real adventures but nobody believes her. This is in part because her brother, knowing she can't keep a secret, tells her enough to know but not enough for her to be believed if she tells someone else.
    • Lampshaded in the Harry Potter fic When in Doubt, Obliviate. After Gilderoy Lockhart complained that Sirius believed that Lockhart had erased his memory before taking him to St. Mungo's that fateful Halloween night, Harry commented that it was the truth.

    Lockhart: "That just makes it worse. Still, at least no one else seems to believe it."
    Harry: "I think it's the way he's phrasing it, really. It makes him sound like it's just a conspiracy theory."
    Lockhart: "I've never tried the whole Cassandra Truth but it's really working for me."

    • In the Ranma ½/Rosario + Vampire crossover Big Human on Campus, Ranma will tell anyone at Youkai Academy who asks him what kind of monster he is that he's a human (which he is). However, only Tsukune and Moka believe him.
    • Neither of Calvin's parents believe him when he describes the bizarre adventures he's been on in Calvin and Hobbes: The Series.
      • Same with Miss Wormwood when grading his paper on Egypt (which he completed by going there himself).
    • Invoked and exploited (or at least an offer is made to do so) by Luna Lovegood in the Harry Potter/Sailor Moon/Ranma ½ crossover fic The Girl Who Loved: after she learns that Cuteness is the daughter of Harry and ghost!Usagi, sent from the future, and that Harry is worried about the secret getting out, Luna Lovegood offers to make use of her reputation and announce it loudly in the Great Hall so no one will ever believe it.

    Films -- Animation

    • In Ice Age 2, Sid is kidnapped in his sleep by a tribe of mini-sloths who wish to sacrifice him to prevent the coming flood. When he stumbles back into camp the next morning, no-one believes his story, insisting that he was just sleepwalking and dreamed the whole thing.
    • Woody from all three Toy Story films. The first movie he was trying to convince the other toys that Buzz was still alive and he didn't kill him. The second one he insisted to Jessie and Stinky Pete that Andy didn't break him intentionally. And in the third one, he had difficulty telling the other toys that Andy really wanted to put them in the attic and not in the garbage.
    • An American Tail
      • The original has Tanya be the only one to know Fievel was still alive after being washed overboard,and Fievel be the only one to know Warren T. Rat was in fact a cat scamming the mice and planning to eat them.
      • In An American Tail: Fievel Goes West, no-one will believe Fievel after he warns them about Cat R. Waul's evil plan to eat all of the mice that he convinced to move west, which Fievel overheard while Snooping Little Kid.
    • The Land Before Time has Cera try to tell the others that Sharptooth isn't dead. Littlefoot convinced them all otherwise until witnessing Sharptooth again try to eat them.
    • In Mulan, when the Huns emerge from the snow, Mulan is the only one who sees it. She returns to the city to inform Shang of this, but he doesn't believe her.
    • In The Nightmare Before Christmas, Sally tries to Jack about her vision of his Christmas being a disaster. Jack, being blinded by his plans, blows her off and then Comically Missing the Point by thinking Sally was referring to his "Sandy Claws" outfit.
    • The Iron Giant toys with this. Earlier on in the movie, Mansley is trying to convince a general that there is a giant metal robot out there, and isn't taken seriously when he does. He was right about that part. However, he was also wrong about the nature of the robot... it was much gentler than he was making it out to be. Eventually, this gets switched around, and the ones trying to convince the army that the giant is gentle are the ones telling a Cassandra Truth.
    • Happens to Mater in Cars 2. Due to his reputation as a prevaricator of fanciful stories (established in the "Mater's Tall Tales" shorts), none of his friends believe him when he tells about his experiences in international espionage.
    • Mr. Tweedy in Chicken Run notices early on in the film that the chickens are plotting something and insists on investigating, but his wife, Big Bad Mrs. Tweedy, will have none of it and forces him to think it's all in his head. Naturally, the chickens are left free to organize a revolt, thoroughly humiliate Mrs. Tweedy, and escape.
    • In Recess: School's Out, the police laugh off and outright mock T.J.'s attempts to tell them that an evil mastermind has taken up residence in the school now that it has been abandoned for the summer. They do this even when T.J.'s friends back him up, and when Ms. Finster tells them that something's going on at the school. The fact that they weren't even willing to believe Finster, a teacher at the same school and thus theoretically a better source than kids also gives them shades of Bad Cop, Incompetent Cop.
    • Cassandra from Hercules. Although in one episode of the ongoing series, the hero becomes pragmatic enough to take her warning seriously, seeing as she tends to be right more often than not.
    • Osmosis Jones infiltrates the villain Thrax's organisation and learns his entire plan—but because he's a screw-up, nobody believes his warnings. Thrax even points this out, and has a laugh over it.
    • In the animated version of Gulliver's Travels (from 1936) the Lilliputian who first discovers Gulliver washed up on the beach is Gabby the town crier; naturally, this discovery causes him to panic and rush back to town to warn everyone; this results in an Overly Long Gag where he tries to warn the king, the king's guards, and everyone else of the "giant on the beach!" but everyone is too preoccupied to listen to him. Ultimately downplayed, however, because when he when he finally gets a word in edgewise, the king does believe him.
    • Tangled also has a Cassandra, and there are many episodes of the spin-off series where Rapunzel and the others do not listen to her warnings when they should. Ironically, however, in "Cassandra v. Eugene" and "Plus Est En Vous", Cassandra herself is the doubter who should have listened.
    • From How to Train Your Dragon; Nobody believes Hiccup's story about the Night Terror at first, and for good reason, as nobody has ever even seen one up close and lived to tell about it. And it's not like he hasn't told stories like this before either.

    Films -- Live-Action

    • Almost every live-action Disney film ever.
      • Jack Sparrow even lampshades this in Pirates of the Caribbean: Curse of the Black Pearl when he tells the two guards exactly why he wants to get onto the ship in Port Royal. He trusts that they will disbelieve him because the truth seems very outlandish and sneaks by them while they're arguing over whether he is or is not lying.
      • In the second film, Norrington is surprised to learn that Jack was telling the truth about Davy Jones' heart. Jack states that he tells the truth quite a lot, yet people are often surprised. Then Will points out that it's because for all the truth he tells, he still lies a heck of a lot. Jack then admits that virtually everything he's told Elizabeth up to that point had been a lie.
      • The song, "I Saw a Dragon" from Petes Dragon is nothing but this trope.
      • Expanded Universe material implies that no one really believed Kevin Flynn either. Then, he goes missing, and no one thinks to check the arcade for hidden doors...
      • Any movie that stars Herbie the Love Bug will have this eventually. Sooner or later the villain will figure out that Herbie himself - not Herbie's current owner - is the one out to get him, and not be able to convince anyone else of it.
    • In Home Alone 3, the cops don't believe Alex's claims that burglars are breaking into neighborhood houses. Somewhat justified in that the cops came in three times. It's just that the industrial spies breaking in to houses were pretty good at running away and leaving no traces.
    • Nobody, not even her husband and therapist, believed Kate's accusations of sweet seemingly nine-year-old Russian Orphan Esther actually being a murderous psychopath.
    • The Good Son revolves around this trope, with the protagonist attempting in vain to warn his family of the homicidal nature of his cousin. The movie was loosely based on the novel The Bad Seed, which also had a Cassandra Truth plot to it.
    • American Psycho
      • At the end, Patrick calls his lawyer and leaves a message on his answering machine where he tearfully confesses that he has killed 20 or so people, including Paul Allen (whose murder is the most important part of the plot). A few days later he sees his lawyer in a restaurant to go speak to him, and is horrified to find that he doesn't believe him, taking it all to be a strange joke.
      • In a club, a woman asks him what he does, and he replies "Murders and executions". But it's loud and she's not really listening, so she thinks he said "Mergers and acquisitions".
      • In fact he basically confesses everything to lots of people throughout the movie, but everyone's too obsessed with their '80s consumerism to notice. Or, it's all in Patrick's mind.

    Patrick Bateman: I like to dissect girls. Did you know I'm utterly insane?

    • The ending of the original Invasion of the Body Snatchers. "THEY'RE ALREADY HERE!! YOU'RE NEXT!!" Actually, come to think of it, pretty much all the Body Snatchers movies.
    • In A Nightmare on Elm Street, no-one believes Nancy when she tells them someone is after her in her dreams.
    • Dr. Ian Malcolm in the first two Jurassic Park movies, but the second in particular; the only character present who experienced what could go wrong when humans and dinosaurs interact, his warnings only seem to be finally taken seriously when the two tyrannosaurs attack the camp, much to his irritation and, well, too late. Of course, no amount of Cassandra Truth stops Malcolm from remaining a Jerkass.
    • In Ghostbusters II, the attempts of the Ghostbusters to warn the mayor that a demonically possessed painting is plotting to destroy the city at 12:00 AM New Year's Day sees them institutionalized, which given how they were right about the events of the first movie, may seem a little harsh (although it was partly due to the machinations of the mayor's scheming aide). In a minor subversion, Peter—who is Genre Savvy enough to see that his colleagues' attempts to struggle against their captors whilst ranting about demonic paintings and the end of the world just makes them look even crazier—merely goes along with it in a calm and reasonable fashion until someone wises up and lets them go.

    Peter Venkman: Don't look at me. I think these people are completely nuts.

    • A common theme in the Final Destination series. Frequently, the initial visions of the hero are only believed by a small number of people. The hero will then try to warn people about death's machinations but will be ignored.
    • In Grosse Pointe Blank, Martin Blank tells everyone at his class reunion up front that he's an assassin, and everyone assumes he's joking. That is, until he is found having killed another hitman using only a pen.

    His girlfriend's father: Good for you, son, it's a growth industry.

    • In Nighthawks a handsome man picks up a stewardess and goes home with her. She asks him what he does as his profession, and he tells her the truth. "I'm an international terrorist wanted in 19 countries." "Well, maybe someday you'll quit the jokes and tell me what you do for a living."
    • Terminator
      • In The Terminator, the psychologist doesn't believe Reese's story about the future and deems him a paranoid schizophrenic.
      • Sarah Connor started out Terminator 2 in an institution for largely the same reasons after being caught trying to blow up a Cyberdyne facility, although admittedly she did have actual issues by that point. In one cut of the film, we see the therapist carted off in a straitjacket and ranting madly after witnessing proof of Sarah's "delusions" come after her.
      • In T3 he has a rant about seeing impossible things indicating he no longer even believes his own memories, then freaks upon seeing the Terminator validating his own memories of events.
      • In the series, the same psychologist responded to the evidence in T2 by moving out of the city and going as far off the radar as possible.
    • Referenced by Mike in Eight Legged Freaks. After escaping the giant mutant spiders' lair and coming across the town sheriff, he is reluctant to tell his story. Make note this is with physical evidence of a giant spider leg that he managed to take with him. After much prodding, he eventually provides a long-winded, detailed explanation of the trope along with what he saw. To his annoyance, he predictably isn't believed.
    • Independence Day
      • David figures out the aliens have embedded their countdown to destroying humanity in the global satellite network. His coworker believes him but is panicky and in no condition to do anything. David's father believes him and takes him all the way to Washington DC, where David's ex-wife blows him off thinking him paranoid. But David is right, and his father wastes no time in reminding people who try to treat David like an idiot. It's really a subversion, because when the president hears him, he believes him immediately.
      • Russell Casse suffers under this every time he talks about being abducted. He even elicits eyerolls from Major Mitchell when he mentions it at the pilots' briefing before an attack on the HUGE ALIEN SHIP! Even so, it is left ambiguous as to whether he actually was abducted by the aliens or was simply crazy.
    • The Sum of All Fears (movie version):

    Jack: Oh... I had a date tonight, so I had to call and cancel...
    Cabot: Well, don't be stupid! Tell her where you're going. In fact, tell her who you work for. She'll be impressed.
    Jack: (to Cathy, over the phone) OK. I work for the CIA, and the Director asked me at the last minute to come with him to Russia with him to do a nuclear arms inspection. Hello?
    Cathy: That is so lame.
    (she hangs up; Cabot laughs)

    • In Back to The Future Part III, Doc Brown has decided to return to 1985 from 1885 and goes to tell his girlfriend Clara the truth about the time machine and when he's from. She is enraged and tells him that it would have been better to just say that he doesn't love her.
    • Happened in Star Trek IV the Voyage Home when Admiral Kirk reluctantly explains to Dr. Taylor that the reason he needs her whales is that he's a time traveler from the future. Naturally, she thinks he's nuts. (This is understandable, because Kirk does only a passable job of blending in to the 20th century.) Eventually circumstances force her to turn to him as her last resort, proving once again that if it's crazy but it works, it's not crazy. When the subject is first brought up, it's kind of funny:

    Taylor: (after Kirk tries to broach what is obviously an awkward subject) Don't tell me. You're from outer space.
    Kirk: (oozing charm) No, I'm from Iowa. I just work in outer space.

    • Star Trek's finest Cassandra Truth occurs in First Contact. Commander Riker and Troi have traveled back to 21st Century Montana and try to convince Zefram Cochrane, inventor of human warp flight and the man responsible for humanity meeting the Vulcans, of the importance of his flight, and why the Borg are trying to stop him.

    Cochrane: So... lemme just make sure that I understand you correctly, Commander. A group of cybernetic creatures from the future have traveled back through time to enslave the human race, and you're here to stop them?
    Riker: That's right.
    Cochrane: Hot damn! You're heroic! (laughs in Riker's face)


    Boris: Who you are working for?
    Wallace: Blockbuster Video, Des Moines, Iowa.
    Boris: Who you are working for?
    Wallace: Blockbuster Video, Des Moines, Iowa.
    Boris: Damn, they trained him so well.

    • In The Wedding Date, Debra Messing's character hires a gentleman escort as her date, so that the rest of her family and her ex-fiancé will be jealous. Later, when the groom asks him how he knows so much about women:

    Nick: I'm a hooker.

    • Twelve Monkeys: Not only does nobody believe James Cole when he tells people he's from the future and trying to gather information about a worldwide epidemic, but his time-traveling shenanigans and insane rantings may have very well inspired said epidemic to begin with. Reversed by mid-movie; his therapist convinces him he IS an insane homeless person; by the time he tries to seek mental help and turn himself in, she's found corroborating physical evidence (a WWI-era bullet in his body and a history text showing his face in the trenches.) She has trouble convincing him he's really from the future. Ironically, said therapist has written a book and given speeches on this trope.
    • Die Hard has one of the most amusing examples of this trope. Protagonist John McClane is attending a Christmas party on the 30th floor of a skyscraper which suddenly gets taken over by terrorists. He pulls the fire alarm in an attempt to get the attention of the authorities, which winds up being canceled by one of the terrorists. He then steals a radio and tries to contact the police that way. Despite audible gunfire in the transmission, the police dispatcher is still unconvinced and informs John he's broadcasting on a restricted channel, prompting the infamous line, "No fucking shit, lady! Do I sound like I'm ordering a pizza?!" It gets even better when she informs him it is illegal to file a false report and he then begs her to send police to arrest him. According to the script, this scene was inspired by a recording of a real 911 call.
    • Early in Night Watch, a police officer asks Anton if he's been drinking, and Anton says "only blood". The cop doesn't believe him—at least until he starts vomiting it up.
    • In the Gremlins film series, the authorities do not believe that a horde of little monsters that can't be fed after midnight are terrorizing the local movie theatre and sporting good store.
    • Played for laughs in Killer Klowns From Outer Space.
    • Averted in Fight Club, where the Narrator tries to confess his alter ego's crimes, and is believed, only to realize that everyone in the room is in on it.
    • Played with in True Lies, where Arnold's character has been placed under the effects of a truth serum whilst handcuffed and immobilised. He's half-drunk from the drug, and the doctor administering the truth drug begins to ask questions...

    Samir: Now, then, is there anything you'd like to tell me?
    Harry Tasker: Just that you're going to be dead soon.
    Samir: Really?
    Harry Tasker: Yeah. First I'm going to grab you, and use you as a human shield, then kill this guy over here. And then I was thinking about breaking your neck.
    Samir: (smiling disbelievingly) And how is that going to happen?
    Harry Tasker: You know my handcuffs?
    Samir: Yes?
    Harry Tasker: I picked them. (holds up the handcuffs; events transpire as predicted)


    Wait, wait, wait! I have something to tell you. By the time this is over...all of you will be facedown on the floor...and I'll moon-walk out of here. You're not listening to me. First, you're going to help me out of my chair. Then I'll leapfrog over you...before I break his nose. Since my trusty lighter...isn't working, I'll do all this With My Hands Tied behind my back.

    • Octopussy, when Bond tries to warn a US general about a nuclear bomb hidden in a circus cannon. Then again, being disguised as a clown probably didn't help matters either. It's a good thing Octopussy believed him.
    • Big Fat Liar is based around this.
    • One of Walken's last leading roles, The Dead Zone is also based around this. He literally is a Cassandra figure.
    • In Choose Me Keith Carradine's character Mickey keeps telling different outlandish stories about his past to other characters and appears to be a compulsive liar. During the movie, the other characters start cross-checking the various different things he's told them and accuse Mickey of lying to everyone. But at the end of the movie, it's revealed that everything he said to everyone was true.
    • In Small Soldiers, Christy tells the police about the attacking action figures. The police don't believe her, at which point she realizes that they will come to the house anyway to arrest her for making a prank call. Instead, they hang up.
    • In The Lady Killers (2004 version) the old lady tries to tell the police that she's found the money from the casino robbery, but the cops don't believe her, instead telling her to donate the money to Bob Jones University.
      • In the original version she tells the police she's got the money from the robbery but the robbers have mysteriously vanished. The constable, thinking it's another of her crazy dreams tells her she can keep it—much to her surprise and delight.
    • Poor, poor Andy just doesn't seem to get a break in the Childs Play original trilogy. He tells people that Chuckie's a killer doll and no one believes him until it's too late. His mom goes through the same thing in the 2nd movie before the main detective believes him after Chuckie tries to kill him while driving his car.
    • In The Last Exorcism, the father pulled the kids out of church and the daughter out of Sunday school because he thought there was something wrong about it. Turns out, he's right. Oh, God, is he right.
      • Did he tell someone who didn't believe him?
    • Troll 2: Nobody believes Joshua about the goblins until it's too late.
    • In the Apocalypse film series movie Tribulation, when Tom Canboro's brother-in-law Jason Quincy (Howie Mandel) is being manipulated by future One Nation Earth agents who want to prevent him from spreading the truth before the world is ready for it, neither Tom nor his wife Susan are willing to believe him due to their past dealings with him that lead to their belief that Jason is mentally unstable. However, Tom's sister Eileen somehow senses that the agent has been in Jason's hospital room and is more willing to believe him, though Tom doesn't believe his sister due to her being a born-again Christian who takes the Bible very literally.
    • In the Bedazzled remake when Elliot tries to tell the police about his Deal with the Devil.

    Elliot: I'm telling you, the Devil gypped me for a hamburger!
    Officer: So, do you have a copy of this contract!
    Elliot: No. I told you, she keeps it in her office.
    Officer: At this nightclub in Oakland?
    Elliot: Yes, at a nightclub, and no I can't tell you where it is.
    Officer: Because you promised the Devil you wouldn't.
    Elliot: No, because she drove, that's why!

    • In the Halloween series, Dr Loomis' entire career in regards to Michael is this. No one ever listens to his warnings about the danger Michael poses to society...even after the dead bodies start piling up.
    • In Cloak and Dagger, from the beginning of the movie, no one believes David G. Osborne until near the end of the movie when his house has been banged up, two dead bodies have been found, and his eight-year-old friend has been kidnapped. Even then, people don't exactly believe him, but they know something is up.
    • The police refuse to investigate the two dead bodies in Mystery Team, simply because the main character is an amateur detective.
    • In The Chronicles of Riddick, Riddick tells the prison guards that he will kill one of them with his teacup. The guard, not believing him, rushes Riddick with a knife, and is promptly impaled on the cup. Riddick then places a tin can key where the cup previously sat. The other guards glance at it, then at Riddick, before hastily leaving.
    • In Zombi 3, we get this little gem from General Morton as his soldiers burn someone infected with the Death One virus:

    Dr. Holder's Assistant: Hadn't it ever occurred to you that the ashes, assimilated into the air, could fall back to Earth again?
    General Morton: That's ridiculous, pure Science Fiction!

    • In Ghost Rider, Johnny Blaze awkwardly explains to his Old Flame Roxie that he is the devil's bounty hunter, which she believes is merely a ridiculous excuse.


    • Most books in the Goosebumps series by RL Stine, in which the protagonists' supernatural claims are disbelieved by parents and authorities. This is turned around in "The Girl Who Cried Monster"; the girl's parents don't believe that her librarian is a monster, not because they don't think monsters exist, but because they're monsters, and they thought they'd eliminated all nearby competitors long ago.
    • In Anne S. Lindbergh's The People in Pineapple Place August's mother does not believe his stories of Pineapple Place, an alley only he can see, filled with families, all of whom only he can see. However, it turns out that his mother is a Reasonable Authority Figure, and comes to believe him once she sees evidence of August's story (a child she (and August) can see, but no one else can, able to get away with considerable mischief, and a security guard, apparently making a fool out of himself in front of a large crowd of people, none of whom (except August) can see the girl he (truthfully) claims to have caught roller-skating in a museum).
    • Any number of examples in Harry Potter
      • “You don’t understand, Professor. Harry Potter’s coming — he’s got a dragon!” "Someone's trying to steal the Philosopher's Stone", "Sirius Black is innocent", "Voldemort has returned", "Draco is trying to KILL people"...
      • Sybill (great-granddaughter of famous Seer Cassandra) Trelawney is regarded as a fraud by her colleagues and some of her students, but the mindful reader will notice that almost everything she "predicts" does actually happen, just not in the way she says it will.
      • An interesting twist on the classic trope is that anytime Ron makes a snarky comment, half the time he's right. In Philosopher's Stone: "I'll kill Fred, he was going on about wrestling a troll." Guess what they're doing a chapter or two later? In Chamber of Secrets: "Maybe he murdered Myrtle, that would have done everyone a favor." And the previous victim of the Heir of Slytherin is... Less obvious examples in Prisoner of Azkaban: "She's still acting like Scabbers has gone on vacation, or something." Surprise, surprise, Scabbers wasn't dead after all, just hanging out in Hagrid's hut. "What would [Hermione's Boggart] have been for you? A piece of homework that only got nine out of ten?" Lo and behold, Hermione's boggart is McGonagall telling her she failed everything. But overall, perhaps not so much them actively not believing Ron, as they're just not paying attention.
    • In Roald Dahl's Matilda, Miss Agatha Trunchbull gets away with outrageously abusing students because "no one would believe them" if they reported it.
    • The Dresden Files has a condition called Cassandra's Tears, resulting in a person having somewhat reliable visions of the future, which no-one believes. If someone does believe, the condition may be cured—but it's easily faked and a common confidence scam among the magical community. Which probably contributes to the fact that no-one believes the predictions. More medically, genuine cases are also easy to mistake for garden-variety seizures, so people not in on The Masquerade, or people in on it but not suspecting the condition, could end up trying to medicate the wrong problem.
    • Cassandra herself shows up in one scene of the Everworld series, displaying just how thorough her curse is. Despite knowing all about her story, and having lived in a world where every myth and legend from all cultures throughout history coexist, the heroes still refuse to believe a word she says, including the statement that she is Cassandra, thanks to the curse's influence. Just to rub salt in the wound, they actually consider making a concerted effort to believe her, on the off chance she is Cassandra, before forgetting what she actually said and then deciding ignore it.
    • Watership Down
      • Part of its premise is a deliberate subversion of the trope with author Richard Adams wondering "What if the Cassandra character was believed?" So in this book, the Waif Prophet, Fiver, is taken seriously by his brother and a select few who escape a doomed warren. There is some doubt when they enter the seemingly idyllic Cowslip's warren that Fiver warns not to enter while the gang ignores him. However, when the place's horrific secret is revealed, the company then accepts Fiver's counsel without question, such as when the group encounters a electricity transmission tower and Fiver firmly tells them that it is of no danger to them.
        • Not all the rabbits who joined Fiver in the first place necessarily believed him (although Hazel did); they were dissatisfied with their life in the warren and thought they'd have it better elsewhere. It's only after he is proven right, both about their home warren and about Cowslip, that that all really start believing him.
      • Not just that, an El-ahrairah short story in the book relies on El-ahrairah constructing a Cassandra out of a suspected spy so that he would lose his credibility and be ordered to leave the warren.
      • The very first lines in the book are a Cassandra quote from Aeschylus' Agamemnon, lampshading this.

    Chorus: Why do you cry out thus, unless at some vision of horror?
    Cassandra: The house reeks of death and dripping blood.
    Chorus: 'Tis but the odor of the altar sacrifice.
    Cassandra: The stench is like a breath from the tomb.

    • James Thurber's The Catbird Seat is about a man who plots to get rid of an incredibly obnoxious woman who works at his office; she's driven away most of his colleagues and is about to talk his superior into cutting out the man's department. The man, a clean-living, sober type who wouldn't hurt a fly, visits her apartment one night, at which point he drinks whiskey, smokes a cigar and discusses his plan to kill his boss using very harsh language. The next day, the woman tries to warn their boss of the man's plan... and is fired when the boss thinks she's having a breakdown.
      • This sounds very similar to what happens in his short story The Unicorn in the Garden.
    • Children's book Voyage of the Basset (the movie Voyage of the Unicorn is based on it) has a mythology-loving college professor whose daughter, Cassandra, is specifically named after this character. Cassandra somewhat lives up to her name when her warnings to her father about what not to do and trouble that could be caused are completely brushed aside, resulting in him getting pissed off and acting nasty to her. He later apologizes when she turns out to be right. (In the movie, he has a nicer personality and the "ignored warnings" thing is avoided.)
    • A short story started with a boy not being able to sleep because he had a fly in his ear. Then all four siblings got up and had a midnight party, playing make believe games so that when the toddler told the parents the next morning they assumed it was a dream, until he mentioned the fly in his brother's ear.
    • Coraline calls the police to tell them that her parents are missing—and she thinks they were taken by the creepy lady with buttons for eyes who lives in the Alternate Universe connected to her house. The police tell her to go back to bed, sweetie.
    • A major part of the plot in the Warrior Cats book Dark River: when a crisis on RiverClan territory forces them out of their camp, the other Clans all start preparing for invasion, since they believe that RiverClan will now try to take some new territory. Hollypaw is seemingly the only cat on the lake that notices that all these fears are founded on nothing but paranoia, and that by preparing for a battle, everyone is making it that much more likely to happen. Naturally, nobody listens to her when she says they should try to help RiverClan with their problem, or at least get more information about it before jumping to conclusions, because she's just an apprentice and they are all "more experienced".
    • This is the whole point of Lemony Snicket's A Series of Unfortunate Events. No one ever believes Baudelaire children, no matter how many times they tell them that their new principal/gym teacher/assistant/captain/chief of medicine/whatever is Count Olaf trying to kill them. Even if the current experience strangely mirrors that of the previous one. Basically, the majority of adults are either evil, will become evil, or are retarded.
    • Night's Dawn trilogy by Peter F. Hamilton. Joshua Calvert always tells a different story over how his father damaged his spaceship The Lady MacBeth, usually involving some form of selfless heroics. Eventually his girlfriend asks for the real story, and is given one involving terrorists and mysterious alien technology. Naturally she doesn't believe a word of it, much to Calvert's annoyance, but a short story by Peter F. Hamilton in another book reveals that he is in fact telling the complete truth.
    • In the Secret Series, the main character is named after the character from Greek legend and is often not believed by adults. A fairly detailed description of the original Cassandra character is given in the first book.
    • In the short story collection Far North & Other Dark Tales, by Sara Maitland, the mythological story of Cassandra is retold as being the result of a Apollo severing her corpus callosum as revenge for her withholding the sex she had promised in exchange for the gift of prophesy. She can see the future, but because of her brain damage cannot articulate clearly enough to be understood.
    • Fanny Price in Mansfield Park tries to warn Edmund that Henry Crawford is constantly flirting with his sister. Who is engaged to someone else. This does not end well.
      • Miss Bates in Emma is also usually right, but her Motor Mouth tendency causes people to tune her out.
      • Charlotte Collins in Pride and Prejudice is also frequently right. Elizabeth assumes she's just jealous.
      • Elizabeth herself, when she tries to warn her father that allowing her sister Lydia to go to Brighton with the regiment will end in disaster. It does. He magnanimously tells her that "I bear you no ill will for being justified in your advice to me."
    • In Stieg Larsson's Millennium Trilogy, Lisbeth repeatedly told authorities as a child about her father's abuse of her mother, but no-one did anything and she wound up being institutionalised after attempting to take matters into her own hands. Of course, there turned out to be a giant government conspiracy responsible for covering up her father's crimes, so this isn't entirely a straight example of the trope. It's also largely responsible for turning her into the person she is today.
    • Played for Laughs at the end of the Dale Brown novel Flight of the Old Dog, where Patrick McLanahan casually tells his mother that he had just come back from bombing Russia. Mrs. McLanahan doesn't believe him. Also used seriously in Plan of Attack, where no one outside of the Air Battle Force believes that a Russian attack is coming, as well as in Edge of Battle where no one believes just how dangerous Comandante Veracruz's plan really is.
    • In Jill Paton Walsh's A Presumption of Death, retired dentist Mrs. Spright is paranoid and senile so nobody pays attention when she claims that there are Nazi spies in Paggleham. It turns out that she's right.
    • In Glen Duncans I, Lucifer, the fallen angel Lucifer casually tells people exactly who is, despite being in a mortal body, only to be seen as joking or eccentric. He even continues being himself when in talks to create a movie on his life story.
    • Jared in The Field Guide, the first installment of The Spiderwick Chronicles, tries to tell his family that faeries are causing all the mischief that he is being blamed for...but, since he's nine and has been acting mischeviously as of late anyway, no one believes him.
    • In the Honor Harrington books, the few Solarians that recognise how far behind the times their Navy is are often casually dismissed as alarmists and defeatists.
    • It would benefit the protagonist of The Longing of Shiina Ryo greatly if he did not suffer from this.
    • Doctor Courtine's testimony in Charles Palliser's The Unburied is brilliant, forensic, mostly true and completely ignored, leading to the hanging of an innocent man.
    • Septimus Heap:
      • In Flyte, only Beetle and Nicko trust Septimus when he tells them that Jenna has been kidnapped by Simon Heap.
      • Jenna tries in vain to warn Septimus of the upcoming Darke Domaine in Darke.
    • Kill Time or Die Trying, Brad spends his entire first day at university trying to figure out where to go. The only reliable directions he's given come from a pair of stoners, who he ignores.
    • In Roger Zelazny's This Immortal, Conrad Nomikos' wife is actually named Cassandra, and when she says at the beginning that she has a feeling he's heading into danger, he tells her he doubts it. He is, of course. At the end, he tells her his new job is going to be an enormous headache, she replies that it won't, and he says she's too optimistic. He even acknowledges that she's been accurate in the past, but this time, he's sure, she's wrong....
    • No one believed Morathi in Sword of Caledor when she claimed that the golden age they lived in would end and daemons would walk the earth.

    Live-Action TV

    • G'Kar of Babylon 5 has been described as JMS's Cassandra; at various points, he predicts what will happen, but no-one believes him, mostly because they don't want to. For example, he tries to warn other races that the Centauri, having conquered the Narn, will turn their attention to others... which they promptly do. It was later revealed that both Delenn and Kosh knew some of his rantings were true but couldn't act in case it showed their hand too early. G'Kar calling Delenn on it when he finally found out was awesome.
    • iCarly
      • The focus of "iTwins". Freddie doesn't believe that Sam really has a twin sister after being pranked twice and not having seen Sam and Melanie at the same time. Also, Carly doesn't believe Spencer's accusations of the multitudes of abuse he got from Chuck.
      • In "iSpace Out", a little girl finds her way into the apartment, but when Spencer tried to show her to a police officer, she'd hidden somewhere.
    • Heroes
      • In the first episode, Claire announces at the dinner table, "I walked through fire today, and I didn't get burned." However, her mother thinks she's just being metaphorical and profound. Although to be fair, her brother was fairly suspicious and her mother isn't the sharpest anymore since the Haitian has been repeatedly wiping her memory which has resulted in the equivalent of punching her brain.
      • Angela Petrelli explicitly references the Trope Namer when she talks about her ability in the episode "Into Asylum". She also states that trying to work around this skepticism is what turned her into the Manipulative Bitch that we all know and love today.
    • Battlestar Galactica'
      • From an early episode:

    Chief: How did you figure that out?
    Boomer: I'm a Cylon.
    Chief: That's not funny!

      • They later built a Non Sequitur Episode around this trope, with Helo trying to unravel a conspiracy that's just so stupid and outlandish it can't be true. It turns out to really be true and everyone walks away with egg on their face (even Helo) because of how stupid they all acted during the event. And then Ron Moore said: "Let Us Never Speak of This Again."
    • Firefly
      • River really is a seer, but since she's also a paranoid schizophrenic, people generally don't listen to her until late in the series.
      • Inverted in the Big Damn Movie. While the Cassandra of myth went insane because nobody believed her, River, who started out insane, regains her sanity after the crew finally believe her.
      • Debatable example but Jayne's opinions are often disregarded because he is, quite simply, an asshat but he also seems to have a point more often than not (finishing the job for Niska, Tams being trouble, bringing grenades on the bank job).
    • This is pretty much half the plot of First Wave. Our heroes try to prevent and reveal the first stages of an alien invasion. No one but a small collection of conspiracy nuts believe them.
    • And long before that, it was the plot to The Invaders.
    • Pushing Daisies:

    Olive: Why'd you fake your death? Is this an insurance scam? Are you and the pie maker in some kind of cahoots together?
    Chuck: I died. And he brought me back to life. Cahoots enough for you?
    Olive: If you don't want to tell me, just say so.

    • Lately, Hank of Royal Pains. No one believes that his father, Eddie R., is as toxic as he claims. Not even Evan. Especially not Evan.
    • Stargate SG-1
      • Throughout the episode "Point of No Return", Martin Lloyd (who's portrayed as a strawman believer in conspiracy theories) tries to convince O'Neill that he's an alien with suppressed memory, and succeeds only after they discover the escape pod in which he landed. In "Wormhole X-Treme!", the situation is reversed: now it's O'Neill trying to convince Martin that he's an alien and subconsciously based the Show Within a Show on the real Stargate program. Martin thinks it's a practical joke and writes down O'Neill's explanations as plot ideas for his show.
      • However, most of the time, the show doesn't succumb to this trope. It's not unusual for a character to experience something highly unusual, like seeing the future, and have everyone believe them. When you've seen as much weird stuff as the SGC has, you become more willing to believe in the unusual. In fact, on several occasions, one character has told the others about a crazy theory/experience... and is met with short-lived skepticism. Short-lived, because it becomes an excuse to list off the other crazy things they've been through.
      • Although one of the earlier instances of this was at the end of the first season, when Daniel Jackson goes into an alternate universe and sees the Goa'uld attack Earth. He claims that he has the coordinates of where the Goa'uld will attack from, but no-one takes him seriously until later on.

    Samantha Carter: Daniel, it's not that we don't believe you.
    Daniel Jackson: So you do?
    Jack O'Neill: No. It's just that... we don't believe you.

    • Jack Bauer on Twenty Four repeatedly takes the role of the Cassandra, which is frankly bizarre when you consider his extensive field experience and the fact that he's almost always right. Though, to be fair the high rate of turnover on the show means that about the only person alive at this point who knows him well enough to trust him is the one who does, Chloe O'Brien. A lot of the field agents will believe him as well, it's just the higher ups that never do. There's actually a saying for this: "If everybody did what Jack Bauer told them to do, the show would have to be called 12."
    • Done in Sister, Sister: Tamera promises her dad to tell the truth for the day, then sees his girlfriend with another man at a movie theater. When she tells him, he's so disappointed that she broke her promise... until he catches her with the other guy when they go out to dinner.
    • Virtually everything John says to his coworkers in New Amsterdam.
    • Used for comedy in this early Monty Python's Flying Circus episode, where John Cleese's Customs officer refuses to believe that Michael Palin's character is a smuggler, despite the fact that he's loaded with contraband.
    • Star Trek: The Next Generation
      • The episode "Samaritan Snare" had two Cassandras. With Riker in command of the ship (due to Picard having surgery to replace his artificial heart) the crew has to deal with a ship manned by Pakled; in a rather confusing Out of Character moment for Riker, he disregards both Troi and Worf's concerns that the Pakled may be more dangerous than they appear. Which they are. It's pretty much a miracle poor Geordi made it out of that one alive.
      • Criticize Wesley all you want, but in "Datalore", he was the first to figure out Lore was impersonating Data, and the first to realize Lore's true intentions. The rest of the crew really should have listened.
    • Star Trek: Enterprise
      • The Xindi story arc features a few of these. Most notably, Daniels has to bring Archer to the future to see the truth of the Xindi's misguided attempts to destroy humanity. When Archer tried to explain to the Xindi that not only was humanity not going to attack them, they were actually going to join forces at some point in the future and defeat a common foe, the Xindi council almost has him executed for his "blasphemy". Admittedly the Xindi did see this foe as gods/angels at the time and they had a different story of future events.
      • In the follow-up episode to the events of Star Trek: First Contact, Archer remembers that Zefram Cochrane related a simplified version of the events of the film. At the time, people had dismissed it as one of his drunken flights of fancy. He gives it more attention now that he's actually dealing with the Borg.
    • Star Trek: Deep Space Nine
      • Subverted in the episode "In The Cards". Jake and Nog's Chain of Deals has attracted the attention of the bad guys, who refuse to believe they're going to all that effort to get a baseball card for Jake's dad. Jake therefore decides to take Refuge in Audacity, and instead claims they need the card for a secret Starfleet mission; Willie Mays is a time traveller, and they have to find out what he was doing in the past. After a moment of uncertainty Weyoun says "I believe you. That is, I believe your first story."
      • In the same episode, Jake and Nog's attempts to tell station personnel that something weird is going on (without mentioning the card) consistently fail when they get to Dr Elias Giger and his "cellular regeneration and entertainment device" (understandably, since the implication of the episode was that this was Techno Babble by Star Trek standards). Weyoun turns out to believe that as well.
    • 3rd Rock from the Sun
      • Dick, guilt-ridden, finally decides he must tell Mary everything about himself to have an honest relationship. He tells her who he is, where he's from, why he's on Earth, and who sent him. Being that they are at a Sci-Fi convention at the time, she merely replies that she is, in fact, an alien sex queen.
      • Another 3rd Rock example: when Dick is facing an IRS audit he finally breaks down and confesses to being an alien, to which the tax guy simply mutters, "Sorry, I've heard that one before."
    • Arrested Development: Michael and George Michael learn An Aesop about being honest with each other after Michael misinterprets his son's behavior. With his father repeatedly telling him that he can share anything with him, George Michael blurts out that he is in love with his cousin Maeby. The mood becomes deathly silent, until Michael realises it was a "joke" on him.
    • Cassandra Spender in The X-Files, with her stories of alien abduction and alien intentions that were deluded and then real. Well, for that matter, Mulder, with his stories of aliens and government conspiracies.
    • In Carnivale, when Libby finally tells her mom the truth about why she and Jonesy were gone all day, that is, that they were kidnapped by some men who tarred and feathered Jonesy and left them in the middle of nowhere, until Ben happened to show up and heal Jonesy, and that Jonesy and Ben went off to find Ben's dad, she doesn't believe a word of it, even though I can't think of any reason why anyone would possibly make that story up.
    • Jake 20 used this a lot. Jake apparently didn't really understand the concept of "secret".
    • This happened nearly every week in the early episodes of Monk; the implausibility of Monk's theory about the crime would be met with disbelief by the police captain, and usually everyone else. The show wisely eventually dropped this, with the captain beginning to accept Monk's explanations due to the fact that he always turns out to be right, even (reluctantly) defending Monk against each week's stand-in skeptic.
    • Dexter, in the episode "Shrink Wrap". Dexter was already planning to kill his therapist for pushing three of his patients to suicide, so it didn't really matter if the therapist believed him or not.

    Dexter: I'm gonna tell you something that I've never told anyone before.
    Dr. Meridian: Okay.
    Dexter: I'm a serial killer. Oh God, that feels so amazing to say out loud!
    Dr. Meridian: Well, you must be letting go, because I've never heard you make a joke before.

    • Power Rangers
      • Mighty Morphin Power Rangers one of the earliest cases of Near Villain Victory came at the hands of a memory stealing monster called Scatterbrain, who managed to wipe the memories of the whole team, causing them to forget who they were or how their powers worked. Who should come to the rescue but those lovable dimwits Bulk and Skull, who stood up to the creature and managed to reverse its spell on the Rangers - at the cost of forgetting most of the encounter themselves, only retaining a vague notion they had done something important. Naturally, almost nobody believes their claims - almost, that is, as the Rangers know, and by telling them that they believe them helps convince them that they aren't crazy.
      • Power Rangers Zeo had a recursive Cassandra Truth, when Bulk and Skull - again - got caught up in an adventure and helped rescue some aliens. None of their friends believed them when they told the story - except the ones that were secretly the Rangers, but when they said so Bulk and Skull assumed they were just humoring them.
      • In the Power Rangers Lightspeed Rescue episodes where the current Rangers team up with the previous group, the plot starts with a young girl discovering that aliens are secretly kidnapping people in the building her father works at. When trying to tell the genial old secretary on the first floor about it, the woman kindly informs her that monsters don't exist. Despite the fact that they live in an area currently infested by demons that attack weekly in an effort to completely wipe their city off the map so they can recreate their ancient society.
    • Lost
      • In "Raised by Another", Claire tells everyone that someone is attacking her in her sleep and trying to inject something into her pregnant belly. They all dismiss this as vivid dreams of a pregnant woman, only to feel suitably guilty when Ethan (who has indeed been giving her injections) kidnaps Claire and almost kills Charlie.
      • Another episode had Sayid traveling back in time to the 1970's along with some other characters. He is forcefed a pill forcing him to tell the truth. He does, and everyone thinks there must be something wrong with the pill.
      • Yet another episode had Hurley finally coming clean to Charlie that he was a multi-millionaire lottery winner. Charlie, of course, thinks Hurley's just messing with him.
    • Doctor Who
      • In the serial "Power of the Daleks", no-one in the colony, who have come to use the Daleks as servants, will believe the Doctor's warnings that the Daleks are evil.
      • Pretty much the same thing happens in "Victory Of The Daleks".
    • In The Listener, Toby has a terrible time getting anyone to listen to the information he learns, mainly because he can't source it without revealing his secret.
    • Mad TV, in a parody of Medium. Allison repeatedly tries to warn the District Attorney of an impending homicide.

    Allison: A man named Martin Grier is going to kill a woman named Susan Monroe at 466 South 27th street.
    DA: I don't understand... Who is Susan Monroe?
    Allison: She came to me in a dream last night.
    DA: I don't understand... a dream?
    Allison: ... Yeah... a dream. Every week I have a dream that helps you solve a crime... Every week.
    DA: I don't understand. Allison, just because you had a dream doesn't mean I can send my men on a wild goose chase.
    Allison: ... Well, you could send them to 466 South 27th street...

      • Oddly enough, it's averted in Medium a lot.
    • Yuri Aso in Kamen Rider Kiva is always being told Cassandra Truths ("I'm 105 years old.", "Your love interest is actually a homicidal monster who wants to use you to repopulate his race.") but never believes them. You would think a professional monster hunter would be less skeptical. Within the series, it's assumed that any monstery things other than the Fangire are extinct because of the Fangire. Why would a professional vampire hunter think that one of her suitors is a werewolf seeking to use her as a baby factory, that his friends the little shoe shine boy and the tall silent masseuse are a fishman and Frankenstein's Monster respectively?
    • In Kamen Rider Decade, self-proclaimed prophet Narutaki spends most of the series claiming that the title character is the Destroyer of Worlds and must be stopped. It looks like this trope because Tsukasa/Decade is doing his best to save parallel worlds and is actually connecting them. This isn't helped by the fact that even people like Kamen Rider Blade Kazuma Kenzaki say the same thing. It turns out Narutaki was right and wrong -- Decade's job is to destroy the multiverse, but Tsukasa's actions in connecting the worlds not only brought them all back but ensured that they would become legends and exist forever.
      • What really makes this a Mind Screw: In the Grand Finale movie, Narutaki reveals himself as Colonel Zol, which suggests that he was trying to get Decade defeated so Shocker would have an easier time taking over the multiverse.
    • On The Office, Jim hid Andy's cell phone in the ceiling and started calling it so Andy would hear his phone ringing but have no idea where it was. Eventually, Jim said "Maybe it's in the ceiling," to which Andy replied, "Maybe you're in the ceiling!" and continued looking.
    • On Wonderfalls, inanimate objects with faces talk to Jaye Tyler. When her best friend, Mahandra, asks Jaye what's wrong, Jaye tells her the truth, which prompts Mahandra to tell Jaye that Mahandra is there to listen to Jaye when Jaye wants to tell her what's actually wrong. She also makes some references to the objects when talking to Eric, but he seems to assume that she's just a very strange person using odd metaphors.
    • On Kyle XY, in one episode, Lori, Amanda, Hillary, and Declan go to a college bar to try and get a DJ for the Prom, and Declan starts a brawl. Later in the episode, when her parents ask her what she did that day, she tells them the truth, only to have it laughed off. Josh also says something along the lines of, "If you wanted it to be believable, you should've left Amanda out of it."
    • Played heartbreakingly straight in Skins, where Emily's coming out to her parents is assumed to be a sarcastic confession but is actually dead serious.

    Emily: I've been making love to a girl... Her name's Naomi. She's rather beautiful. So I was nailing her.
    Rob: OK, OK, I get it. Nice one, had me going there! (continues to bust up laughing)

    • In The 4400, Maia had a vision that Jordan Collier was going to be assassinated. Her mother brought it to Collier, but he didn't believe her. Later seasons had a better track record of believing the psychic kid, eventually fully subverted when one of her visions was finally believed, only to be revealed that she was lying about it so that Collier and the rest of the P+ would let her and their other captives go.
    • According to a recent CSI: Miami flashback episode, Horatio was this when he first joined the Miami PD, dealing with lethargic cops who wanted to put the wrong man behind bars because he was the right culprit according to their antiquated methods—but not according to Horatio's observation and desire to try new methods. As if he couldn't be any more of a God Mode Sue.
    • A Red Dwarf episode features a computer called Cassandra who can predict the future. However, her predictions aren't always as clear-cut as they seem and she tries to manipulate people by giving false predictions. In an interesting variant, though, she had been abandoned not because no-one believed her predictions, but because no-one wanted to hear them (because accurate truths about the future were often uncomfortable). She's not a perfect example of a Cassandra however, because her veracity was never really in doubt. However, Rimmer was so determined to believe that the 1st prediction of his death had some kind of Prophecy Twist that he actually managed to cause the twist and have another crew member die whilst wearing Rimmer's name tagged jacket. He changed his tune, however, when the 2nd prediction of his death involved him having sex with Kochanski. Also, all her manipulations of the Red Dwarf crew came about because she was trying to alter her future and prevent her own death, which the end of the episode showed was impossible: she died due to Lister accidentally causing a chain reaction started by a piece of chewing gum.
    • During an episode of The Invisible Man, Darien's ex-mentor shows up at his place to catch up and offer him a stake in her heist.

    Liz: You went up for life on a third strike rap, it was in all the papers. How'd you get out?
    Darien: Well... if you must know, I was pardoned by a secret intelligence agency who surgically implanted a gland into my brain to turn me into a super-agent.
    Liz: ... You don't wanna talk about it. That's cool.

    • Happens often in The Twilight Zone.
      • An episode of the original Twilight Zone features a man who travels back in time, right before Abraham Lincoln is shot and killed at Ford's Theatre. He tries to prevent Lincoln's assassination and ends up in jail for acting "drunk" (until he is bailed out by John Wilkes Booth, who believes his story).
      • "The Time Element", the rarely-seen TZ pilot that aired on the Westinghouse Desilu Playhouse, has a similar plot about a man traveling back to 1941 Honolulu just prior to the Pearl Harbor attack.
    • Done hilariously in Merlin when he ran into the throne room, claiming he was a wizard, to protect Gwen who was about to executed. Arthur (who doesn't know about Merlin being a wizard) comes to his rescue, by saying he was in love with Gwen and claiming that there was no way an idiot like Merlin could possibly be a wizard.
    • Kelly in Harper's Island sees John Wakefield, the Ax Crazy Big Bad, alive. No one else does and they all believe that she's insane. Turns out he's alive and dangerous. It's likely she's one of his first victims because she knows the truth. Kelly does have a habit of insisting that You Have to Believe Me though.
    • Gordon Walker in Supernatural finds out about how children like Sam are supposed to be part of a demon army and tries repeatedly to convince Dean that Sam is evil and must be killed. And then in the beginning of Season 5 -- oops! -- it's revealed that Sam is, and has always been destined to be, the vessel for Lucifer. But then in the season 5 finale it's subverted, because, as Bobby had pointed out in the previous episode, if anyone could overcome the effects of Satanic possession, Sam can. Which, thanks in part to both The Power of (Brotherly) Love and to Dean's heroic stubbornness/suicidal co-dependency, Sam does.
    • An episode of Beyond Belief: Fact or Fiction? features a story where a little boy insists that there's a monster in his closet and is tormented mercilessly by his older brother and a pack of bullies because of it. Finally, the boy dares the brother to go stand in the closet with the door closed. The brother does, and, following some terrified screaming, their Mom opens the closet door to find that the brother HAS DISAPPEARED. The really scary thing? The story was listed as "Fact".
    • One episode of Family Matters had Carl becoming especially angry at Steve Urkel for some reason, and throwing him out of the house. Steve was trying to warn Carl that the lamp he was fixing had a dangerous short circuit in it, and that Carl shouldn't plug it in, but the sneering Carl just ignored him and told him to leave. As Steve heads for the door, Carl plugs in the lamp and becomes electrocuted, and would likely have died if Steve hadn't come back and given him CPR.
    • In Charmed, Phoebe tries to tell her sisters about Leo's true identity. Naturally, it's treated as a joke.
    • Buffy the Vampire Slayer falls victim to this trope more than once.
      • It is usually in the earlier seasons but Giles and her other friends often do not believe the hunches Buffy gets about upcoming evil events and who is responsible for them. The most notorious example may have been when she told her friend that her new college roommate, Kathy was not human and held up a bag of her clipped toenails as proof. They actually trapped her in a net, tied her to a chair, and tried to warn Cathy. Turned out she was a demon from another dimension. Although it's later revealed Cathy was slowly stealing Buffy's soul, which was causing her to act in a very bizarre manner. The end of the episode even indicates that Buffy just can't stand having roommates.
      • When Buffy first became the Slayer, she tried to tell her parents, who responded by putting her in a mental institution. She eventually stopped talking about it, and got to go home. Or did she?
    • In Nikita, Nathan asks Alex what's bothering her. He figured she was in some kind of trouble with the mob, or something. Alex finally spills the beans because she's planning to escape and she's worried Division will interrogate or kill him. Nathan believes her story about government conspiracy agents is a diversion to deny what's really bothering her.
    • In an episode of Seinfeld, George is truthfully attempting to explain away a very strange series of coincidences to an old childhood friend, who is convinced that George is going insane and doesn't believe his (admittedly odd-sounding) explanations.
    • In Breaking Bad season 3 episode 1, Hank help Walt move out. He takes a bag full of money and when he asks Walt what is making the sport bag so heavy, Walt replies: “half a million in cash”. Hank thinks it's a joke and laughs.
    • Once Upon a Time: Sure, kiddo. Everyone in this small town is a fairy-tale character with amnesia. Your (adopted) mom hauled you into a shrink and you end up calling the shrink Jiminy Cricket. You're a little messed up in the head...hey, wait. What's your mom doing with those shards of glass and that door in the graveyard...?
    • Wil in Season 2 of The Amazing Race. He never missed an opportunity to tell his ex-wife Tara that helping out fellow racers Chris & Alex was a bad idea, and they should be concentrating on the race instead of helping another team. Though he was ultimately proven right when Chris & Alex passed them up in the finale, he was portrayed as a villain because of this... that and he was a Jerkass.
    • In an episode of Frasier Daphne tries to explain that her Greek friend Zena will soon be arriving on her (the friend's) mother's ship, but the other person thinks she's talking about Xena arriving on an alien mothership.


    • This trope is a huge part of the Ayreon legendarium. In The Final Experiment the protagonist, Ayreon, is sent visions from the future about the end of the world and travels to King Arthur's court to warn him. Merlin is jealous, convinces everyone that Ayreon is wrong, and realizes that was a bad idea too late. He predicts that another seer will come: Mr. L in 01011001 has dreams about the end of the world sent to him by cyborg fish aliens; unfortunately, he's in an insane asylum.
    • Emilie Autumn's Bedlam House chic is heavily based on her belief that psychiatric institutions have not progressed that much with patient care: specifically, she alleges that abuse is rampant but never gets brought up because "[she's] the crazy girl and he's the doctor with a million dollar education".
    • Go listen to "Cassandra" by ABBA. Just do it.

    Myths and Religion

    • The trope namer: Cassandra from Classical Mythology, theater, and literature, as featured in The Iliad,The Odyssey, the lost epics of the Trojan Cycle, The Aeneid, and many others!
      • Some versions of the myth have Apollo putting a curse on her so that people would never believe her prophecies—because she falsely promised to have sex with him to get her precognitive power! The moral of the story is: Don't lie to gods. The actual Aesop: get the sex first, then give her the power.
    • In some versions of the King Arthur story, Merlin has this problem; see, for example, this Arthur, King of Time and Space strip.
    • Numerous Biblical prophets, most notably Jeremiah and Elijah, spent much of their lives trying to convince the public in the Kingdoms of Israel and Judah that exile was imminent due to the people having strayed from the Torah's commandments, and the monarchy in particular having turned to idolatry. This was often met with hostility, particularly from the monarchy.

    Newspaper Comics

    • In the newspaper comic Safe Havens, at one point a school photographer snagged a photo of Remora's mermaid transformation, but when he presented it to the school principal she simply denounced it as a photomanip, as Samantha had already shown her several photomanips in advance. Samantha later apologized to him, telling him she had to do it to protect Remora's secret.
    • In a Tempest strip, when Tempest awakes in an interrogation room, he quickly and clearly tells the questioner that Deathfist and his daughter have broken out of prison and are on their way to Times Square to punch a hole in the space-time continuum. When the lie detector says he's telling the complete truth, the interrogator jumps to the conclusion that he's figured out how to fool it.
    • Bloom County's Steve Dallas called the police one New Year's Day to report some very bizarre events in his house: man-eating bananas in the bathroom, and a nine-foot-tall talking cucumber in the kitchen. The desk officer assumed he was still soused from New Year's Eve partying. Then the cucumber came in behind Steve, with a towel wrapped about its "waist," and expressed shock about the bananas infesting the bath.


    • A quite magnificent example in the first episode of Series Two of the BBC Radio 4 comedy The Casebook of Inspector Steine. As it begins, Mrs Gloynes, the police station tea lady who is actually the crime boss of 1950s Brighton, has been laying low since the highly intelligent PC Twitten discovered her secret and agreed to keep quiet if the crimewave stopped. Near the end, the constable is reluctantly dragged on stage at a music hall and hypnotised to believe that "this charming Cockney charlady is a criminal mastermind". The episode ends with crime rates up again, and Steine telling Twitten that if there's no way to snap him out of this delusion, the least he could do is keep quiet about it.

    Tabletop Games

    • Mage: The Awakening features "Proximi", families with a magical heritage, limited magic, and an unbreakable family Curse. Particularly noteworthy are the Primid family, said to be descended from Cassandra with a gift for prophecy, and who originally shared her Curse. They eventually tried to use it to their advantage (deliberately making predictions that they knew people would act against, as a way to manipulate them), so the Curse altered itself accordingly (the point of Proximus Curses being that they are always bad, and change themselves to fit loopholes). Now, the Primid Curse is that they are incapable of accurately conveying their prophecies at all (that is, they will know the future, but will be unable to truthfully tell it to anyone else).
    • One Ork codex for Warhammer 40,000 has a flavor quote about Ork Kommandos, where the guardsman who survived the attack is executed for covering up his cowardice by inventing a story of half-glimpsed shadows. Orks being a race of Leeroy Jenkins, sneaky orks are of course a rarity, making them all the more effective.


    • In Sweeney Todd: The Demon Barber of Fleet Street, once Mrs. Lovett's pie shop starts doing business again, the Beggar Woman starts hanging around the shop, trying to warn people that something evil's afoot, pointing out the stench from her chimneys and claiming that Mrs. Lovett is a witch. Naturally, no one believes her because she's a mad beggar woman.
    • Trope Namer: Within The Oresteia, in the play Agamemnon by Aeschylus, Cassandra gives a prophecy revealing Clytaemnestra's plan to kill her husband, Agamemnon. In somewhat of a subversion, here a character does try to listen to Cassandra, but doesn't understand a thing she says, and then asks her to stop talking about such horrible things, because they would never happen.
    • Julius Caesar: By the time Caesar learns that he should pay more attention to soothsayers, it's too late. He also learned too late that it's not a bad idea to install metal detectors in the Senate.
    • In Pygmalion, act III, when Eliza is taken to a party, Nepommuck remarks that she can't be English, because her English is too perfect. Higgins replies, paraphrasing here, "Well, I think she sounds like someone taught by an expert, probably from Drury Lane." Notably, the host of the party goes with Nepommuck instead of Higgins. Obviously, Higgins was the one telling the truth.

    Video Games

    • A meta example: If you say you're lagging in an online game, nobody believes you. They think you're just making up excuses for sucking... even if you really are lagging. And even in games where you get to see your teammates' latencies.
    • A "mysterious sorceress" in Suikoden III wanders into Karaya Village with a prophecy that the village will be attacked by Zexen forces and that everyone should clear out immediately. Nobody believes her, and the village is destroyed. Of course, the reason she knew about this is because she was part of the plot, and just wanted to minimize casualties.
    • The Pokémon Absol [dead link] sense danger and natural disasters and go to the people to warn them of the upcoming disasters. However, nobody listens to them, and thus the whole species has a horrible reputation for being the ones to cause disasters.
    • Eternal Darkness: No, really. The darkness DOES come and will damn us all if nobody stops it, so may the rats eat your eyes for not listening to Max Roivas.
    • In Knights of the Old Republic 2, you arrive in Iziz spaceport looking for a Jedi master, smuggled aboard the personal shuttle of the Mandalorian leader. Feel free to tell the customs officers any of this, they won't believe a word.
    • Mass Effect
      • The entire damn story. Specifically, it's understandable for The Citadel Council to be skeptical of a lone human warning of ageless giant robot monsters from outer-outer space coming to wipe out all galactic life, at first. But after said human and their cohorts are proven right, time and time again, in everything else they've told you, some smidgen of acceptance wouldn't kill you!

    Turian Council Member: Ah yes, (air quotes) "Reapers".

      • This occurs within the game itself, in regards to the player. On the very first mission you encounter an apparently insane scientist that you (and the other characters) dismiss for being nuts as he's rambling. He's utterly correct about everything. One of the random planets you can scan has a description indicating it was bought by a millionaire who went nuts because voices in his head told him about an enemy he's looking for weapons to fight...he also is spot on in his description of who the Big Bad of the series is.
      • Lampshaded in the third game, where Legion reveals that the Geth collective believed his evidence about the Reapers returning from Day 1.

    Shepard: ...That must have been nice.

    • Happens in Final Fantasy X, where no one will believe Tidus about being from Zanarkand.
    • Persona 4
      • Played for laughs when some of the party members explain what's really happening concerning the murders, in detail, to an inquisitive detective... but because the truth sounds so absurd and the characters in question are completely drunk (sort of), they are immediately disbelieved. Said detective however is eventually confronted with the truth to her face and apologizes for not believing them before, though pointing out how absurd the truth really is. The police however flat out never believe you. Especially not Detective Dojima, who demands that the protagonist tell him what's going on, only to hear the truth and not believe it. This happens not once, but twice in a matter of moments.
      • Although it's played tragically with Taro Namatame, who actually suspects something after the first murder, fails to convince the second victim, and is brushed off by the cops when he thinks he knows the next target; of course, his story was crazy and he was being played by the real killer. In fact, you can put the final nail in the coffin by not believing that he didn't murder anyone, and throwing him into the TV world as punishment.
    • In Arc Rise Fantasia, the party (and the player) is quick to jump to the conclusion that Rastan is Leon, which Rastan corrects at every opportunity. It comes as quite a shock that this was the truth all along, and it's a major headdesk moment when everyone realizes that Leon is actually Serge, who fits all the clues just as well as Rastan and hasn't been denying it all along. He's just not what anyone was expecting the legendary Lightning Leon to really be like.
    • Warcraft
      • The Prophet in Warcraft III tries to alert the human kingdoms of Lordaeron to the threat of the Burning Legion, but only Jaina Proudmoore heeds the call and takes an expeditionary force to Kalimdor. Lordaeron is destroyed by the Scourge, who bring forth the Burning Legion.
      • Also played with in the Warcraft Expanded Universe novel The Shattering: Prelude to Cataclysm with the old Shaman Drek'thar. His visions were still heeded despite a growing level of senility up until the point where his vision of a peaceful meeting of druids being attacked by orcs, and sending of troops to provide protection, leads to a false alarm and increased distrust by the Night Elves. Later in the book however, this attack does occur, and Drek'thar's caretaker is horrified when he realizes that, not only was Drek'thar right all along, but his most recent visions were about an upcoming Cataclysm.
      • In Patch 4.3 of World of Warcraft, if you talk to Bishop Farthing and tell him that Archbishop Benedictus, who supposedly left to help the Dragon Aspects, is actually the Twilight Prophet, he will first laugh it off, and if you insist that it's true, he will scold you for believing and spreading false rumors, mentioning to one he heard about Bolvar (whom everyone thinks is dead but is actually the new Lich King).
    • Glory of Heracles DS has Cassandra herself show up, and gives a different reason why her prophecies are unbelieved: when she tries to give them, half the words are rendered unintelligible. Only Achilles can hear her prophecies, and he gets offed pretty fast. Eventually, the party takes her into a room lined with stone that cuts off the power of the gods, and her curse lifts long enough for her to give them her prophecy (which basically says "Typhon is coming").
    • This plays into the ending of The Breach: our hero has survived, but he's a nervous wreck locked in an insane asylum, and since he blew up the spaceship to destroy everything on it, he has no way of convincing anyone of what really happened, and no way to prevent the experiment from being replicated. Then he turns into a monster and apparently eats his psychiatrist. On camera. Well, at least that ought to put a stop to the experiment...
    • Golden Sun
      • Feizhi is essentially a kung-fu Anime Chinese Girl Cassandra. Several of the NPCs in Xian are indicated to believe her visions, after the first two came true... but her father not only disbelieves, he rebukes her for having a vision that her friend was caught in a rockslide and worrying about him, which is the part our heroes see before she runs off in tears to find her friend.
      • Saturos and Menardi. They tried to explain the situation to the Vale elders, but when they didn't believe them, they were forced to take drastic actions.
    • Chrono Trigger: After the Time Key gets stolen and you go find it, Azala asks you what it does. If you tell him, he doesn't believe you, saying if it were true, you wouldn't tell an enemy.
    • In Splatoon, the reason Cap'n Cuttlefish has to Recruit Teenagers with Attitude (including the player) to help him is because none of the adult Inklings believe his claims of an impending attack by the Octarians. Well, nobody except Callie & Marie, but the player doesn't learn that until later.

    Visual Novels

    • In Tsukihime, the day after fighting and killing Nrvnqsr Chaos Shiki is given the option of telling the truth about what he had been doing the past few days to his sister Akiha. She simply laughs at his explanation, but in reality she actually probably believes his supernatural story, being a supernatural being herself.
    • In Remember 11, Kokoro and Satoru attempt (and fail) to convince their respective companions that the two of them are experiencing random personality transfers.
    • In the Visual Novel Hourglass of Summer the protagonist tries to warn the girls of the future events he's seen from traveling randomly through time against Lee Jane's warnings not to. It fails because nobody believes him and the tragedies happen to them anyway. Subverted by Kaho where the letters he writes to her warning her against going to the train station on the day she dies are simply never delivered by her overly controlling father.
    • One of Corpse Party: Blood Covered's Bad Endings has this: Satoshi finds himself sent back to the day they performed the ritual that sent them to Tenjin. Unfortunately, he can't convince anyone not to go along with it, as they all assume he's just too scared and superstitious rather than having good reason to protest. Book of Shadows actually picks up from this ending and deals with the results.

    Web Animation

    Web Comics

    • Bardsworth. This strip, and this one too.
    • Here in Sam and Fuzzy.
    • At the end of the "To Thine Own Self" arc of General Protection Fault, Trudy tells the rest of the cast that she wants to stay behind in the Nega-verse and atone for what she did, knowing that it's better than going to jail for the rest of her life, and asks that they bring her counterpart to the real world. The building shakes, knocking Trudy out, and Nega-Trudy comes to, putting on the pin to make them think she's the real Trudy. She then tells them to take the real Trudy back, claiming that she will be delusional after coming to and will falsely claim to be the real Trudy. Trudy attempts to explain that she is the real one several times, but to no avail.
    • Sluggy Freelance
      • In this strip, Bert predicts Torg "fleeing for his life while flying by the crotch planet in the giant space crotch," and Torg reacts exactly as you'd expect. Three and a half months later, Torg and Riff are riding the crotch of "GOFOTRON" past the "planet of the naked nymphomaniacs" to escape a warlord.
      • Played straight in this strip.

    Torg: Remember Oasis, the killer-robot who was ordered to love me and then blew up in a massive explosion with her creator?
    Riff: I was supposed to BELIEVE that? I thought it was "make up a big fat lie" day.

    • The Order of the Stick
      • Kind of inverted with the Oracle, who has a spell placed over his entire valley, so that once people leave they forget everything about their stay except for whatever prophecy he gave them. So, while they're able to act on the prophecy itself, anything else that happens in the valley is forgotten, including any plot-significant revelations or information. Needless to say, visits to the Oracle usually make Hilarity Ensues.
      • Another interesting example of this: Roy, suspecting that the Oracle will try to trick them with an overly-literal prophecy, carefully words his question about which of the Gates Xykon will attack next. However, the way Roy phrases this leaves out one of the possible Gates—which, as it turns out, is the one Xykon is going to attack next. The Oracle tries to explain this, but Roy refuses to believe him, and winds up accepting the literal answer to his question instead, even though it's not accurate. He does eventually realize his mistake, though... just in time for the memory spell to come into effect, making him instantly forget it.
      • Yet another interesting example (though Played for Laughs) here—Haley tells the truth completely, but the others are suspicious of her -- which is exactly what she wants. Haley quite often does this—with the Linear Guild and now with Elan's father. Is she the only one able to spot obviously evil people?
      • Explaining that he and a main character are wrongly imprisoned, Thog tells it just exactly like it is here:

    Thog: not nale. not-nale. thog help nail not-nale, not nale. and thog knot not-nale while nale nail not-nale. nale, not not-nale, now nail not-nale by leaving not-nale, not nale, in jail.


    TG: skepticism is the crutch of cinematic troglodytes
    like hey mom dad theres a dinosaur or a ghost or whatever in my room. "yeah right junior go back to bed"
    fuck you mom and dad how many times are we going to watch this trope unfold it wasnt goddamn funny the first time i saw it
    just once id like to see dad crap his pants when a kid says theres a vampire in his closet
    be fuckin dad of the year right there

      • Later played heart-rendingly straight in this memo from Karkat to the troll's past selves. During it, a few of the people who really should be paying the most attention to it miss the point or dismiss it as more of Karkat's outrageous nonsense. Namely, Feferi, Eridan, and Gamzee, who have respectively: died at the hands of Eridan, switched sides and killed two people as well as possibly blinded a third, and gone completely batshit insane and gone on a killing spree.
        • Arguably this counts as Crying Wolf, seeing as at this point Karkat has rambled and been a jerk for so many sweeps-worth of memos that nobody is going to listen to him, even if what he's trying to say is important.
      • Mom Lalonde's Alpha Counterpart seems to know more about Betty Crocker and her true intentions than anybody else seen so far (save for Nannasprite). However, Jane, the one person who needs to know these things the most, refuses to believe her. Jane's disbelief is justified due to the fact that she's being brainwashed and Alpha Mom is a Bottle Fairy. Jake seems to believe what she has to say.
      • Later, undyingUmbrage warns Dirk (correctly) that Lil' Cal is an abomination that can only lead to pain and suffering for all, even noting that awareness of this is so important, he's willing to give the warning despite being a complete asshole. Naturally, Dirk assumes this is more jerkery and professes Lil' Cal to be his best friend.

    • Get Medieval: Sir Gerard went on a pilgrimage to Santiago and wound up piloting a spaceship to the moon. When he tells Lady Eleanor this....
    • Questionable Content
      • In this strip, Marten and Dora return from a "walk" with different clothes (in particular, Marten is wearing Dora's trousers) and a completely incredible story involving kung-fu monks. Faye obviously doesn't believe them... but it turns out to be the truth.
      • Then here, Marten explains that he came home late with a stop sign in his hand because he and Steve were fighting off a vigilante on a vespa who thought Steve was abusing his girlfriend. Dora immediately dismissed this explanation and decided he went to a strip club and brought home the stop sign as part of a cover-up. Factoring in the part where he would've had to somehow reason that stealing a stop sign was the best way to create a cover-up, this is one of the few examples where the implausible truth is actually less implausible than the thing everyone else assumes. Also kind of funny that Faye reasons he's telling the truth because the strip club part is too far-fetched.
    • A Loonatics Tale: Riley often sees unsettling or downright sinister things going on around him (like a bug zapper that can fry a songbird, or, in a particularly Fourth Wall Observer moment, the bush outside his house as seen from the perspective of a man with a cartoonishly Sugar Bowl worldview), but no-one ever believes him when he tries to warn them.
    • In Dominic Deegan, the eponymous seer runs into this problem when he tries to convince Chance Masters and his family that an extradimensional monster will kill Chance if he participates in an upcoming tournament. They believe he is a charlatan who is trying to exploit them. A fairly justified example: Dominic had a nervous breakdown in public on his record, the threat he is trying to warn them about would be unbelievable to anyone without Dominic's unique perspective, and the Beast is invisible to most seers—Dominic can only see it due to unique circumstances. Also, the Master family had had first person experience with being conned by someone claiming to be a seer who had seen a vision of impending danger to them.
    • Schlock Mercenary has an officer who got both this problem and its solution.

    • #109 of the Evil Overlord List: "I will see to it that plucky young lads/lasses in strange clothes and with the accent of an outlander shall REGULARLY climb some monument in the main square of my capital and denounce me, claim to know the secret of my power, rally the masses to rebellion, etc. That way, the citizens will be jaded in case the real thing ever comes along."
    • In the Paradise setting, this frequently applies to characters who try to convince others that they have been invisibly transformed into Funny Animals but just don't look that way to normal people. There are ways to short-circuit the Weirdness Censor temporarily, however.
    • Sean Malstrom accurately predicted the rise of the Wii to first place in the seventh generation all the way back in 2006, when others were expecting the Wii to follow in the footsteps of its predecessor in terms of commercial success. However, Malstrom hasn't exactly become famous for this thanks to his controversial opinions on other gaming-related subjects overshadowing everything else.

    • In The Amazing World of Gumball, no-one except Gumball's family believes him when he says "Our dad ate our homework".
    • King of the Hill
      • When Bobby Hill tries to tell his father about something he's proud of himself for doing, Hank dismisses him because he is so used to Bobbies disappointments as a son.
      • When a snipe hunt gone wrong results in an endangered crane being killed, Boomhauer confesses to a park ranger and the gang thinks their cover's blown. The ranger just tells them to carry on.
      • Another episode has a variation, where Peggy correctly guesses events but gets the motives behind them wrong. Bobby damages Peggy's lawn gnome, and Hank uses this as a pretext to get rid of it; when he confesses, Peggy thinks Bobby is to blame for the whole thing. Later Hank buys a replacement gnome and lets Bobby give it to Peggy to smooth things over; again, Peggy assumes that Hank took pity on Bobby and got the replacement as an apology.
    • On Animaniacs, cartoons featuring Chicken Boo revolve around this concept. Chicken Boo, a giant chicken wearing human clothes, shows up as a renowned expert in some field. Exactly one person immediately sees through the Paper-Thin Disguise, and is exasperated that no-one else will believe that "He's a chicken, I tell you, a giant chicken!" In one of the first Chicken Boo stories, "The Man with no Personality", it's possible that the townsfolk thought the Cassandra-Man of the story was accusing Boo of being a coward.
    • On Pinky and The Brain, one of Brain's standard replies to suspicious people is to state exactly what he and Pinky are and what they are trying to do. Nobody believes it, or seems to find it odd that they're talking with mice.

    Security Guard at the White House: Aren't you a little small to be wallpaper hangers?
    Brain: Actually, we are two lab mice trying to take over the world.
    Security Guard at the White House: Oh, you silly wallpaper hangers. Go on in.

    • Avatar: The Last Airbender
      • Jet goes through this when trying to warn people that Zuko and Iroh are firebenders that are trying to infiltrate the city. After spending several days trying to get proof, he loses all credibility when he decides to suddenly attack them in front of a bunch of customers to get them to firebend in defense, which leads to his capture and Brainwashing by the Secret Police. The sad thing was, in that instance he was wrong in his fears. Those firebenders weren't trying to do anything evil. It just makes the second season ending really ironic.
      • In Jet's first appearance, Sokka also went through this while trying to convince Aang and Katara that Jet planned on wiping out an entire village just to take out some Fire Nation soldiers stationed there. Jet's plan would have worked as even the towns people didn't believe him until the elderly man that Sokka saved earlier backed him up.
    • Invader Zim: Dib is the only human who instantly recognizes Zim as an alien dangerous to humanity. A Running Gag throughout the series involves him trying to reveal Zim's true species to the world, only to have no one believe him, either due to Dib acting too crazy to be believed, through Zim's counter actions to protect himself, or the people in the Invader Zim world being drooling morons. Interestingly, Dib's sister (Gaz), knows full well Zim is an alien, but says almost nothing about it, mostly because she believes (with quite a bit of justification) that Zim is too incompetent to be a threat.
      • One noticeable example where just after Zim claimed himself to be a human at school, his giant alien boss comes through the ceiling and jetpacks with him away. Dib tries to finally get the students to open their eyes but all they noticed is the bird poop that just landed on Dib's head.
    • The Simpsons
      • Bart is attacked by a wolf at school. Naturally, because he's "cried wolf" so many times before, no-one believes him.
      • Another episode, "Simple Simpson", has Homer taking on a superhero identity: Pie Man, who throws pies into the faces of wrongdoers. Towards the episode's end, rather than submit to an attempt to blackmail him into pieing the Dalai Lama, Homer outs himself as Pie Man. Nobody believes him as they all think Homer would never be smart enough to even come up with a secret identity in the first place.
      • Another from The Simpsons: Homer has been barred from Moe's Tavern, and has borrowed an airline uniform in order to gain access to the pilot's bar:

    Man: We need a pilot, pronto!... You!
    Homer: But I --
    Man: Hey, you're not just impersonating a pilot so you can drink here, are you?
    Homer: Yeah. That's exactly why I'm here.
    Man: (laughs) You fly-boys, you crack me up!
    Homer: (being pushed into the cockpit) But I keep telling you I'm not a pilot!
    Man: (brusquely) And I keep telling you you fly-boys crack me up!

      • In "Hungry, Hungry Homer" Homer goes on a hunger strike because no-one will believe him when he finds out that Duff Beer is planning to move the local baseball team to Albuquerque. Homer even provides a fitting quote for this trope, which you can see on the quotes page.
      • "Bart Simpson's Dracula" from "Treehouse of Horror IV".

    Lisa: Mom! Dad! Mr. Burns is a vampire, and he has Bart!
    Mr. Burns: Why, Bart is right here.
    Bart: (monotone, with noticable bite marks) Hello, Mother. Hello, Father. I missed you during my uneventful absence.
    Homer: Oh, Lisa, you and your stories. "Bart is a vampire." "Beer kills brain cells." Now let's go back to that... building... thingy, where our beds and TV... is.

      • In "Treehouse of Horror VI", Homer is abducted by Kang and Kodos who tell him that they plan to kidnap President Bill Clinton and Senator Bob Dole and take over Earth during the 1996 Presidential campaign. Homer tells the aliens that he is going to tell everyone and put a stop to their evil plan. They spray him with rum and then send him back to Earth, saying that no one will believe him. Of course when he gets home and tells the family, no one believes him because they think he got drunk at Moe's.
      • Chief Wiggum treats everyone like they're telling Cassandra Truths. Even to the point where an obvious arsonist walks into the station to give himself up. Wiggum dismisses him as a loon not worth listening to.
    • Phineas and Ferb
      • Candace suffers from a severe psychosis due to the fact that she can't convince her mother that her little brothers make a habit of violating the laws of common sense, physics, or current technological progress. Every time she tries to expose them, some remarkably convenient plot device eliminates the evidence just as their mother arrives on the scene. Her mother has commented on this being a delusion, making it reasonably close to an accurate adaptation of the original portrayal. For that matter, she doesn't believe Phineas and Ferb when they back Candace up, merely assuming they're "imaginative". Actually a subversion, as it seems Linda's the only person in Danville that doesn't know about at least one of Phineas and Ferb's projects. (With the exception of the animal translator in "Interview with a Platypus", where she thought that it was cute but didn't get suspicious at all.)
      • Mirroring Candace's problem (but not getting so worked up about it) Doofenshmirtz's daughter Vanessa can't convince her mother that he's an evil Mad Scientist.
      • Whenever Phineas and Ferb are getting industrial supplies trucked into the backyard, the contractor will look at Phineas and ask, "Aren't you boys a bit young to be doing this?" and Phineas'll respond, "Why, yes, yes we are." Word of God is that they think the two are child prodigies (why else would they be ordering all of these things?), and if the delivery people were actually smart enough to not give them the items, they wouldn't accept them.
    • Almost everyone in Code Lyoko that doesn't actually see the Supercomputer for themselves have an extremely hard time believing it exists. Not that they ever remember they were told about it in the first place... Most notable example is the second episode, "Seeing is Believing", where Yumi tries to convince the principal and some firefighters that XANA is launching an attack on a nuclear power plant. Nobody believes her.
    • Similarly, the Canadian cartoon Kid vs. Kat falls under this when an alien-looking cat ends up being taken in (and accidentally stranded on Earth) by an unsuspecting family. Save for the son, Coop, who's rightly convinced the cat has evil intentions leading into conflicts between the two. However, most of their scuffles end up with Coop holding the bag and no one believes him when he tells what really happened.
    • In the episode "Identity Crisis" of The Spectacular Spider-Man, Venom has revealed that Peter Parker is Spider-Man. The common reactions throughout the large cast of the show are laughter, disbelief, and momentary consideration ("it would explain a lot...").

    Aunt May (looking around for hidden cameras): Am I being punked?

    • In The Powerpuff Girls episode "Keen on Keane", Ms. Keane, a cat owner, gets angry at the Professor when he admits he hates cats. When he explains to her that he hates them because one made him jump off a building (a reference to an earlier episode, "Cat Man Do"), she doesn't believe him. Which is pretty ironic in that, with all that happens in Townsville, an evil cat seems pretty plausible.
    • South Park
      • Stan finally decides to come clean and tell the town that he destroyed a beaver dam and caused a massive flood in a neighboring city. The adults of the town, being complete idiots, interpret this as him saying that everyone in South Park is to blame for the destruction of the dam. The episode ends with everybody in the town saying "I broke the dam," and Stan's yelled confession being ignored completely.
      • In "Spookyfish" when he tells his mom that his fish is killing people, she doesn't believe him.
      • In "The Biggest Douche In The Universe," Stan makes his own rival show to John Edward's "Crossing Over." He begins every episode by saying that his (and Edward's) statements and "communications" were simply tricks and hoaxes. No one believes him.
    • Hey Arnold! has a hilarious Cassandra Truth involving Curly and a football game. Every time the team leader attempts to make a play during huddle, Curly tells him to "Just give him the ball". After being ignored multiple times, Curly irritates the leader so much that he lets him have the ball. During said play Curly then uses his subsequent ballet lessons to his advantage, plié-ing away from others to avoid being tackled, making a touchdown. This makes his team very happy, until of course Curly runs off into the distance, still holding the football and laughing maniacally.
    • This video mercilessly parodies the use of the trope in an episode of the original Transformers.

    Chip: Megatron's cheating!
    Jazz: Shut the fuck up, Chip!

    • The plot of Chip 'n Dale Rescue Rangers episode "Seer No Evil" is built upon this trope, right down to the bug who offers predictions to the Rangers being named Cassandra.
    • Occurs in an episode of The Penguins of Madagascar. While on night watch duty, Private consumes too many sugary snacks and ends up on a serious sugar buzz, when he sees a "sky orca" (shortened to "skorca"). He tries in vain to convince the other three penguins, both of whom only look for it when it's not in the air. They even fake being attacked and carried off. Later on, they (along with the lemurs and Joey the Kangaroo) find it and defeat it for real, unaware that it was actually a parade float.
    • This happens in Batman Beyond where Terry tries to tell his family the truth about his secret identity before it's revealed on TV. They laugh in his face.
    • On Family Guy, no-one believes Peter when he says he heard the world was going to end at midnight from a chicken-man. Although since the episode was All Just a Dream, it wasn't real anyway.
    • My Little Pony Friendship Is Magic.
      • Subverted when Princess Celestia responds to Twilight Sparkle's discovery that Sealed Evil in a Can Nightmare Moon is about to escape her confinement by telling her to get her head out of her books long enough to make some friends. Ultimately, though, the case proves to be that Celestia knew that Twilight was the one in the best position to defeat Nightmare Moon, and sent her to a place she would potentially make the friends she needed to fully use the Elements of Harmony.
      • Later played straight in "Swarm of the Century". While everyone else is trying to drive the Parasprites out of town, Pinkie Pie is running around looking for instruments. At first she's just passed off as being 'typical Pinkie Pie', and eventually yelled at for getting in the way- until it turns out the only way to get rid of the Parasprites is to lure them away with music. Of course, it didn't help that Pinkie never actually told anyone what she was doing...
      • Zig-Zagged in the season 2 finale. Twilight claims Princess Cadence is evil. Technically speaking, Twilight is completely wrong. The Changeling impersonating Cadence, however...
    • In one episode of Superman: The Animated Series, Lois asks how a hayseed like Clark could possibly keep edging out a veteran reporter like herself for headlines. Clark responds that he's actually Superman and uses his job to find out about disasters in advance while taking the opportunity to scoop Lois. She responds "You're a sick man, Kent" while stalking off.
    • In Rollbots, No one believes Spin that Vertex is actually a Spider, and they have even greater difficulty believing that he is the one orchestrating all of Flip City's crime. Only when Vett appears does anyone consider Spiderbots a viable idea, but only Penny accepts that Vertex might be a criminal mastermind. However, it turns out that Captain Pounder and Ms. Appie knew the whole time.
    • In Spider-Man: The Animated Series, a group of villains working for the Kingpin kidnap Aunt May, leaving a ransom note demanding that Peter send Spider-Man to their headquarters. The plan works, but when they overpower Spider-Man and unmask him, only the Rhino (who is a little slow) believes at first that they have caught the real Spider-Man. The rest all think that Peter had been unable to find Spider-Man and had come disguised as him. (The fact that Spidey had temporarily lost his powers and had put up a pretty pathetic fight was probably the biggest reason.) In fact, Silvermane is disgusted with the Kingpin for "doing nothing but grabbing a harmless old woman and her nephew", which the big boss doesn't seem to take well...
    • Hilariously done in The Flintstones episode "Ten Little Flintstones". When Fred tries to explain to Wilma, Barney, and Betty that his odd behavior is the result of aliens using ten clones of him to invade him and he stopped them, everyone laughs. Wilma thinks it's stress from his diet and tells him he can go off it. Fred is upset for a few seconds, but then realizes Wilma said he could go off his diet.
    • In the original version of Disney's version of "Chicken Little" (from 1943), Foxy Loxy is depicted as far more malevolent, being the one who convinces the eponymous character and her friends that the sky is falling by spreading rumors around the farm. Cocky-Locky is the Only Sane Bird among the flock, trying to talk sense into the others, as he realizes this is a trap, but they don't listen, and the cartoon ends much the same way the original fable did. Seeing as Cocky-Locky is a gravely-voiced rooster who wears a suit and smokes a cigar, it is obvious just which Cassadra he is supposed to represent in this propaganda cartoon.

    Real Life

    • Carroll Edward Cole arguably qualifies as a particularly frightening Cassandra. From the Wikipedia entry: "He attempted suicide at least once, and on a number of occasions, had himself committed to mental hospitals where he confessed his fantasies of murdering women. Although diagnosed as a psychopath, Cole was usually discharged promptly, as he had a personality disorder, as opposed to a mental illness -- the former was considered to be untreatable by psychiatrists at the time, unlike the latter." In his later career as a serial killer, Cole claimed 16 victims.
    • One of Al-Qaeda's spokesmen recently released a furious attack on 9-11 conspiracy theorists who believe that Al-Qaeda did not plan and execute the 9-11 attacks. They even went so far as to claim the predominantly Shiite country of Iran was backing the conspiracy theorists to discredit Sunni terrorists. Even funnier because The Onion had released a parody news report earlier that year that was pretty much the same thing, triggering a Hilarious in Hindsight moment.
      • In addition to this, many 9/11 conspiracy theorists believe themselves to be telling Cassandra truths.
    • The book Dead Men Do Tell Tales relates the story of a bitter old man who regularly threatened his neighbors by declaring he had murdered his son-in-law and buried the body in a septic tank, and he would be willing to do the same to them. When the old man died, they cleaned out his house... and found the son-in-law's corpse in the septic tank.
    • William Lloyd Garrison, a founding father of the American Abolitionist movement, as well as abolitionists generally. Turns out slavery's wrong, guys.
    • The Monty Hall problem. [1] Magazine columnist gives an answer to a math problem. Mathematicians around the country tell her she's wrong. So what does she do? Write a letter of apology? No. She asks elementary schools around the nation to prove that mathematicians can't do math. She's right!
      • Considering that probability problems like this are notoriously difficult to understand for anyone, including mathematicians who do not specialize in probability theory, this doesn't particularly prove that "mathematicians can't do math." If anything, it proves that even columnists aren't always talking out of their asses. It's a nice way to demonstrate how non-intuitive even seemingly trivial math problems are, though.
      • One reason that this problem poses so much difficulty for a lot of people, including brilliant mathematicians and scientists, is because the scenario is often presented with a crucial piece of information missing: The host knows in advance which doors have goats behind them, and no matter what door the contestant chooses, the host will then open a door with a goat behind it. If the person describing the problem leaves that information out, and implies that the host always opens a door at random after the contestants choose, and it just happened in this scenario that the door had a goat behind it, then the odds involved would be completely different.
        • I'm pretty sure that is implied in the problem. It would defeat the whole point of the contest if the host happened to open a door with the car behind it.
        • Not to mention her logic falls apart when you realize Hosts really could care less if they win or lose usually, as it's more about the spectacle of the event, and regardless they are trying to hype up everything, not deceive the player into losing. Basically by her logic and the way she perceives the host and the question, she is correct, but from a strictly statistical viewpoint, she is incorrect.
        • I'm afraid you're wrong - if the host opens one of the other doors randomly, and it has a goat, it is exactly the same as if he knew ahead of time that it would have a goat, from that point onward. Why? Because if the opened door has a goat, the situation is exactly the same as it would be if that door was chosen intentionally. What does change is the probability of winning on the switch prior to a door being opened by the host. In that case, the probability of winning is 1/3 no matter whether you intend to switch or stay, rather than having a 2/3 chance of winning by switching - but if the door that opens has the goat, then you have a 2/3 chance of winning from that point by switching (total probability is 1/3 because there's a 1/2 chance that the door with the car is opened, in which case you have 0 chance of winning). I know, it's hard to get your mind around, but it's true. The only way to get a 1/2 chance is to randomly choose between the remaining doors.
    • During the 1964 Republican National Convention, Presidential nominee Nelson Rockefeller was met with a chorus of boos when he made a speech warning that fellow nominee Barry Goldwater was too far to the right to be elected. The Republican nomination went to Goldwater anyway, who was eventually defeated in a landslide by incumbent Democratic President Lyndon Baines Johnson.
    • Martha Mitchell, wife of Nixon Attorney General John Mitchell, claimed that President Nixon and the White House were engaged in illegal activity. She was diagnosed as being mentally ill.
    • In 1992, Sinead O'Connor tore up a picture of Pope John Paul II during a performance on Saturday Night Live to protest sexual abuse of children within the Roman Catholic church. At the time it was enormously controversial, but less than 20 years later, multiple incidents of the church's abuse of children, and coverup of the abuse, became an international scandal.
    • Strangely, famous magician Harry Houdini sometimes became the Cassandra. He consistently told people that everything he did was a trick and not magic. Still, many people, like Arthur Conan Doyle, insisted that his tricks actually were magic.
    • When he was young, a hypnotist visited Mark Twain's town. His friend went up, but was less than a perfect subject. Just to get attention, young Samuel went up and did everything the hypnotist told him to, even hurting himself. When he went back to visit his elderly mother, decades later, he confessed, only to find that she actually argued with him that the hypnotism was real.
    • During the American Revolutionary War, George Washington was prepping for his famous attack on Trenton. The entire attack could have been derailed had Johann Rall, the Hessian commander, listened to the spies and deserters who repeatedly warned him of the impending attack.
      • In one of the Animorphs Megamorphs books (the third) this is exactly what happens as part of the Big Bad's plans to rewrite history. The result? Washington dies, as does Jake, the leader
    • A strategist told the Navy that, thanks to advances in aircraft carriers, Pearl Harbor would be highly susceptible to aerial attack, especially if the Honolulu-area airbases kept their aircraft so close together. The people in charge said that such an attack was impossible, and if it did happen, it'd be unlikely to be very large. Sabotage was the bigger threat. The aircraft were kept together, in the middle of the field, where they could be watched. The result: the QUITE LARGE Pearl Harbor attack was able to wreck virtually all of Hawaii's USAAF aircraft on the ground.
      • Militaries tend to be the epitome of bureaucratic inertia, generally changing tactics only when their previous ones become completely untenable (whether due to lack of men or materiel or political issues). It's often said that they prepare to fight the last war.
      • It gets worse: an aviation-minded admiral "attacked" Pearl Harbor with carrier-based planes in February 1932 (on Sunday the 7th, no less) during a war game. If the bombs and bullets had been real, the place would've been a wreck. The powers that be basically lied, claiming that his planes were never in the right positions to do that much damage. The attack came from the same direction and used the same persistent cloudbank for a concealed approach as the one not quite ten years later.
      • On the other side, the Japanese architect of the attack, Admiral Isoroku Yamamoto, warned that if Japan waged war with the USA, they would have the advantage for six months after which USA would get the upper hand and keep it. Of course, Japanese government didn't listen and six months after the Pearl Harbor attack, the Japanese fleet is irretrievably crippled as an offensive force at the Battle of Midway.
    • Political Correctness Gone Mad: In both that trope and its inverse, this trope is in effect. Legitimate concerns about certain groups may be classed as bigotry and legitimate objections to bigotry may be dismissed as idiotic.
    • The tragic story [dead link] of Robert Turner, a six-year who dialed 911 when his mother passed out, only for his call to be treated as a prank, leading to the death of his mother.
    • A general meta-instance of this can happen if one tries to explain a series with high levels of Mind Screw to someone who has no knowledge of it, particularly if they've actually asked for information. It's not uncommon for the reaction to a completely truthful answer about Metal Gear Solid or Neon Genesis Evangelion to be something like, "You're just making all this up."
    • Sadly invoked in many real life cases of bullying, you can tell your teacher about all the (often horrific) traumas that you suffer, but until you show up with a black eye/bleeding/seriously injured/found unconscious, don't expect anyone to believe you, and rarely for the bully to actually be disciplined. (And even then you'll be lucky if they do punish them.)
      • Dave Pelzer wrote A Child Called It about his experiences as the victim of the third-worst case of child abuse in Californian history. The evidence was clear across his body on a daily basis, up to broken bones (and worse!), and yet the school officials took several years to conclude it was bad enough to intervene. Worse because the couple of times he tried to tell, early on, they'd just call his mother, and send him back to her, and she'd abuse him even worse - so he stopped trying to tell anyone at all.
      • Terry Knorr.
    • How many of you actually believed that Tropes Will Ruin Your Life? Huh? HUH?!
    • After World War I, most people in France's military establishment believed that the best way to defend against a future German invasion was to build a large fortress wall across the border to defend against it. The result was the Maginot Line, a barrier that Charles De Gaulle repeatedly insisted was ineffective and would not protect France from German attack, as they could simply go around it. No one believed him. Guess what happened when World War II came around?
      • Answer: the Germans did pretty much what they were expected to do, with two exceptions. No one on the British or French side expected the Germans to be stupid enough to attack the Line directly, so they knew they'd be forced to go around the north, and the two countries' plans were based on that (the reason the French built the Line was because, after the losses in World War One, they didn't have a large enough army to defend the entire border, so the goal was to force the Germans somewhere a defending force could be concentrated). The two surprises were the German paratroop attack on the Belgian fortress of Eben-Emael, the capture of which gave the Germans more room to maneuver and forced the Allies to hastily redeploy, and their attack through the Ardennes which was considered too dense to move effectively through. The real Cassandras were the advocates of armoured warfare, like DeGaulle, who realized that forcing tanks to merely be infantry support and spreading them out instead of concetrating them was not using them effectively.
        • A pity, because the French had some damned good equipment, especially the Char B1 (at 10-to-1 odds it would still come out on top against Panzer IIIs and IVs).
      • The biggest Cassandra of all? Winston Churchill. He'd been warning since 1933 how much of an issue Hitler might be, but he wasn't believed until it was too late to avoid war.
        • It's more complicated than that. People like Chamberlain was almost certainly aware of an inevitable conflict with Germany and/or Japan, and his strategy of appeasement was more a means of giving Britain enough time to build up a military response. Churchill simply insisted on attacking sooner, rather than later.
        • No, the biggest Cassandra was probably Hitler himself. He made his goals very clear in Mein Kampf, but almost no one took him seriously.
      • Speaking of WWII: "Where they burn books, they end up burning people".
    • Ferdinand Foch, Marshal of France in World War I said that the Treaty of Versailles that officially ended the war in 1919 was not a peace but "an armistice for twenty years."
    • Starting in 2000, financial analyst Harry Markopolos spent approximately eight years trying to warn the Securities and Exchange Commission that Bernie Madoff was running a Ponzi scheme. He went so far as to send them a detailed memo entitled "The World's Largest Hedge Fund Is A Fraud" that listed 29 reasons why he was suspicious of Madoff. The SEC paid very little attention to Markopolos, leaving Madoff free to keep swindling people out of their money until his 50 billion dollar Ponzi scheme finally collapsed in 2008.
      • There was a documentary on the subject where a number of people had stated they saw this coming, but when they warned others, specifically in the Jewish community, they were shouted down for their statements because Madoff had kept up the appearances of being an affluent philanthropist, especially to charities geared at the Jewish community.
    • There's an old story about Richard Feynman (he recounts it himself Surely You're Joking, Mr. Feynman!), about two guys in his college dorm who were noisily obsessive about the door to their workspace being closed at all times. So one day, as a prank, Feynman stole the door. Eventually, after several days of no one being able to find it, a meeting was called and all the residents were charged on their honor to admit whether or not they stole the door. When it came around to Feynman, he said, "Yeah, I stole the door." "Stop joking around, Feynman, this is serious." When Feynman finally returned the door and once again reiterated that he'd stolen it, everyone asked him why he hadn't owned up at the meeting; all anyone could remember was that they'd gone away under the impression that no one had admitted to taking it.
    • This trope is unfortunately much more common in MANY more ways that people realize. Many people point out how awfully stubborn and ridiculous believers in certain conspiracies are with this cognitive failure to acknowledge reality, and I agree that quite a few are, particularly with regards to the Moon landings. However, what an eerily large number of people refuse to talk about is how the anti-conspiracy crowd can be just as bad, if not worse, than the conspiracy theorists they belittle so much...
      • Can you name a single example of a theory that was widely considered to be a "ridiculous conspiracy theory", that turned out to be right (and not so vague that it's easier to satisfy than the typical horoscope prediction)?
      • Senator McCarthy's claims that the Communists had infiltrated the US government and Hollywood. While he was wrong about which individuals were the infiltrators, the 1991 declassification of various KGB records showed that he'd actually been right all along about the infiltration.
    • A prime, and quite disturbing, example of this kind of Cassandra Truth is the very unfortunate story of journalist Gary Webb. In the late 1990's, he published a series of articles that detailed CIA drug smuggling from Nicaragua and other countries into the USA and how much of the drug dealers involved seemed to target poor blacks. The mainstream media, and even some alternative news sties, went absolutely haywire. They viciously attacked and smeared Webb, and caused him to lose his career and his reputation. The kicker? Less than a year after Webb's articles were published, a investigative committee led by federal prosecutor Fredrick Hitz published a report that confirmed that the CIA was indeed in collusion with the Contras re: drug smuggling (although the parts alleging that they invented crack and specifically targeted poor urban blacks were not confirmed). Yet it wasn't until after Webb's death in 2004 that any of the media acknowledged they had really dropped the ball. Worse still, many more people, media or otherwise, continue to selectively forget the entire affair.
      • Almost the exact thing happened with college professors of Arabic who were discouraging people from entering into Arabic classes to thwart the CIA (who was funding students to recruit Arabic speakers in their war on terror). The whistle blower was unable to convince anyone that the story was true, it simply seemed outrageous, until 6 months later they found emails between language professors all across the US detailing the truth of it all.
    • Happens frequently on the show Untold Stories of the E.R., which is about real E.R. doctors and nurses and the weird situations they encounter. For example, one episode had a schizophrenic patient who kept claiming that he had someone else's face. The doctors just assumed that he was off his meds and hallucinating until he showed them his drivers license and the picture actually looked different. Turns out the poor guy had lung cancer. Another one was a father who claimed worms were coming out of his infant daughter's hands and he turned out to be right.
    • During World War Two on the New South Wales South Coast there were once two brothers at a remote beach and they witnessed a Japanese submarine’s crew land to take on more water. The older brother hid the younger one while he ran off to the nearest police station to tell the authorities. The police did not believe him and locked him up over night while the other brother was still out there. Needless to say this story has become legendary in the local Eurobodalla Area
    • Hussein Kamil Hassan al-Majid, Saddam's son-in-law and head of Iraq's WMD program defected in 1995. He told the world about the extent of Iraq's WMD programs, which was widely believed and widely reported. He also mentioned that the programs were destroyed. He even told CNN that.
      • There is, however, an understandable tendency to give statements against interest a higher weight than statements in interest. (In plain English, people are more likely to lie to make their side look better rather than lie to make them look worse.)
      • There's also that the primary concern re: Iraq's WMD programs is the belief that they had been restarted after 1995.
    • Former baseball slugger Jose Canseco wrote a book about his time in baseball which pointed the finger at several of his teammates taking steroids. He goes into detail about certain players, most of the All Stars, would go about using them. Due to Canseco's less-than-pleasant personality, this all was completely brushed off as him trying to make some money. Then came the Mitchell Report and it turns out Canseco was telling the truth.
    • On June 19, 2015, Ann Coulter was a guest on "Real Time with Bill Maher". When asked who she thought would win the upcoming Presidential election, she unhesitatingly answered Donald Trump. They literally laughed in her face. One can only imagine the victory lap she took after Trump did actually win.
