The Cassandra

""Allison. You had a nightmare that a woman named Susan Monroe was going to be brutally murdered by a man named Martin Greer? That could mean anything!""

- Mad TV parody of Medium

A character is almost always right about something (or everything) and yet continues to be mistrusted, mocked or otherwise ignored. You would think that after several years, the other characters would get the idea, but they seldom do, and then when they do, it's usually the one time the character is wrong, so as to maintain the status quo. To be fair, the character usually has some sort of personality quirk that makes them seem less believable, but a near-perfect track record really should be enough.

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 trope Older Than Feudalism.

In natural Disaster Movies or Science Is Bad stories, The Cassandra will usually be an Ignored Expert, a scientist or other expert acting as the lone voice of sanity warning against a particular course of action that will, of course, be taken.

Subtrope of Cassandra Truth. Compare Crying Wolf, where a character is not believed because he's always lying, and Dude, Where's My Respect?, which is often the result of this. See also Harbinger of Impending Doom.

If The Cassandra is a Waif Prophet or an Oracular Urchin, this may be because of All the Other Reindeer.

 * In Space Jam the basketball players, whose talent was stolen by the tiny aliens ask a cliché fortune teller, who actually finds out their problem (Talent stolen by tiny little aliens to play a basketball game against Bugs Bunny), but because it sounds too weird, they don't believe her.
 * The Good Son uses a variant on this when the.

Live Action TV
"Stottlemeyer: Is he sure? Disher: (beat) He's Monk!"
 * Dr. House is pretty much always right, he even says so, and yet, the other doctors continue to contradict him in every which way.
 * This is justified and heavily subverted because he's also consistently wrong for most of each episode, and occasionally (though rarely) wrong all the way through. He's almost always eventually right, not always right. The reason he has the other doctors around is to prove him wrong until he's right.
 * They hang a lampshade on this in one episode, where House has to diagnose an epidemic on a plane without his usual medical team. He recruits a few passengers to help his thought process, giving instructions like "Contradict everything I say."
 * In Firefly, River freaks out = something bad happens is common, and yet Simon still always tries to convince her that there is nothing to worry about. Finally subverted in the movie, where they use her ability to sense trouble as an early warning system.
 * In Mal and company's defense, she is crazy. Remember the fear of Book's hair?
 * And if Zoe didn't have things to do, she'd be hiding with River.
 * Monk, while generally given some degree of respect, is often not believed despite being right almost every time.
 * The people who know him have learned to believe him, even when his theories sound crazy.


 * Though he's pretty much guaranteed to be disbelieved if he suspects a murder while on vacation.
 * Psych has Shawn, who acts psychic to give the police a reason, however flimsy, to listen to him. Now they often request his help, but they continue to display disbelief. Shawn's antics seem to simultaneously raise and lower his credibility.
 * There was a Dead Ringers sketch which parodied this by having TV characters known for this given a new boss who enthusiastically praised their track record and agreed with what they had to say.
 * Jack Bauer. The guy's saved the world's ass how many times? And still people never listen to him when he's right and do everything in their power to keep him from breaking protocol.
 * See This Sluggy Freelance
 * The Doctor. How many times has he charged around trying to get people to believe what he's saying? That he's talking about alien invasions and often dresses like a complete weirdo probably doesn't help his case. And unlike many other people on this list, he's usually not dealing with the same basic cast every episode.
 * Subverted in the new series: UNIT trusts the Doctor, just not enough to listen to his advice about . Also, using a metaphor involving the sonic screwdriver and a pane of glass, he managed to convince Yvonne Hartman, leader of Torchwood 1, that the dimensional device was tearing holes in reality and she had to stop. That didn't prevent the Cybermen and the Daleks from invading, though.
 * And in the episode "Midnight", it becomes apparent that without a companion around,  - resulting in total Nightmare Fuel.
 * On one occasion, while within the biggest library in the universe, he convinced a group of aliens to "look him up". They do. And behave themselves afterwards.
 * Recent seasons have many people believe that The Doctor is technically right, but there wouldn't be trouble in the first place if he'd just stay the hell away.
 * Except after seeing "Turn Left" it turns out every bad thing he prevented would have happened anyway even if he'd died in the first episode of the season. the only reason the earth wasn't destroyed entirely was because of the secondary characters picking up a bit of the slack (not enough, but some).
 * Dangerous Davies, The Last Detective, is always right when he suspects there's more to a death than meets the eye. This does not stop his DI from belittling and ignoring him whenever possible.
 * Sam Tyler had some of this in Life On Mars.
 * Mulder gets a fair amount of this on The X-Files. Of course, this can be expected when you go around spewing epileptic trees. Sometimes, he may get the details wrong, but the overall theory will be right. Other times, he uses a shotgun effect and throws out a bunch of different theories, but one of them is right.
 * 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.
 * And other times, people who know he's telling the truth *ahem* Delenn and Sinclair *ahem* won't back him up because they don't want the information getting out yet.
 * In an episode of Columbo, some corrupt local politician pulled strings to have Columbo assigned to investigate the crime he committed, thinking Columbo was too "bumbling and stupid" to catch him... even though Columbo had successfully solved every single case he'd ever been assigned to solve (or at least all the ones seen by the audience).
 * This was common with early-season Columbo.
 * Alison DuBois of Medium gets this from her own husband almost Once an Episode. (Interestingly, the district attorney and his lot are much more open to believing her - they only refuse to act because it would bring suspicion on them, not because they discount her abilities). She has a dream and wakes up freaked out next to him; Joe tells her to go back to sleep because it was "just a dream". This despite the fact that every week she has a prophetic dream, and the entire plot revolves around how she prevents, corrects, or figures out what her dream meant.
 * Well, it's nothing compared to Scanlon...
 * One episode of Red Dwarf's eighth season introduced Cassandra, the AI who could see the future . They weren't even trying to be subtle there.
 * In Veronica Mars, Veronica will, without fail, get to the bottom of any mystery, embarrassing the guilty Jerk Jock, Alpha Bitch, or idiot sheriff in the process. Despite this, the town residents only ever react to her questioning them with smug indifference.
 * Not only that, but she spends the entire first season trying to figure out who killed her best friend, Lilly. It turns out to have been  Unfortunately, when it goes to trial   Even worse,   Seriously though, you think these people would learn to trust V's gut once in a while.
 * Rumzan the punkah wallah in It Ain't Half Hot Mum. Much of what he observes early on is often borne out by the end of an episode, but no-one pays any attention, presumably for racial reasons.
 * Lost's Sayid Jarrah has remarkably correct intuition in the early seasons...but more often than not it's ignored by Jack, etc. See Three Minutes, where Sayid deduces that Michael is, but can't stop Jack, Kate, Hurley and Sawyer from following him right into a trap.
 * Throughout the first season of Merlin Morgana was seldom believed when she had a prophetic nightmare about something. Somewhat Justified in that she was afraid to reveal her powers and so passed off her visions as vague "feelings about things" and Subverted in that the people who did believe her wanted to keep her in the dark about how accurate her dreams really were.
 * In Homeland, Carrie Matheson is right about everything, always. No one believes her, ever, not even Saul, her friend and mentor. Of course, given that she is bipolar....

Literature

 * In one novel set in Troy, Cassandra herself exploits her curse in a moment of Genre Savvy as the main character is trying to escape the city by calling out that someone is trying to leave through the gate. The main character panics for a moment until she realizes that because no one believes Cassandra no one is bothering to look at her, giving her a chance to escape, and Cassandra blows her a kiss from her tower.
 * No one listens to Mikhail Kutuzov in War and Peace. Battle of Austerlitz? Bad idea, says Kutuzov. The Russians intervene and get their asses handed to them and Napoleon conquers Austria. Oh well, no big deal.
 * Several of the earlier Sherlock Holmes stories, perhaps most particularly A Study in Scarlet, show the great detective being mocked by the official police for his unusual methods and seemingly bizarre theories. Over time, however, as they find he's right almost unfailingly, the police shift their opinion and become admirers of Holmes. Lestrade even comments on it in The Adventure of the Six Napoleons, saying that they're not at all jealous of him at Scotland Yard, but on the contrary, "we are very proud of you."
 * Harry Potter, despite being The Chosen One, frequently gets this treatment in his own books, especially from his best friends. So much so that Dumbledore freely admits that part of his Batman Gambit in the seventh book is counting on Hermione's Arbitrary Skepticism to slow Harry down long enough to think things through properly.
 * Harry's not the best example, as he's usually very, very wrong (he knows what's going to happen, but he's usually wrong about who), and in hindsight its obvious that listening to him would have been a bad idea.
 * In a way, Professor Trelawny is a reverse Cassandra, as the only time she dismisses one of her predictions is when it's correct. The most obvious example is when she predicts that  will return to Voldemort. A more subtle one occurs in Half Blood Prince. Harry is hiding from Trelawny, who's wandering drunkenly through the school, and pulling cards from a deck. Though it's never stated, it's entirely possible she's doing a reading on Harry. One of the cards she interprets as meaning the subject dislikes her (Harry can't stand Trelawny). She thinks about it for a second, and says "that can't be right," and starts going through the cards again.
 * The title character of Barbara Hambly's Antryg Windrose Chronicles uses Holmes-ish deductive reasoning to figure out things that everyone else then assumes only the villain could know. Between that and his checkered past, he's never believed by anyone in a position of authority - and on the rare occasions when this is not true, he winds up being banned, banished and locked up anyway for telling truths people don't want to hear. Fortunately, he has the patience of a saint.
 * Astrid in Garry Kilworth's novel House of Tribes is known far and wide for her prophetic powers. Naturally, when one of her visions is politically inconvenient, everyone comes up with reasons to assume she's wrong and blunders ahead anyway. After her vision comes true, her prophetic stock shoots up twenty places...until the next vision, which is again inconvenient and is again ignored by quite a lot of characters. There's a message in there somewhere.
 * Heralds of Valdemar: In Arrow's Fall, Empath Talia has demonstrated a flawless track record of reading people, but is still doubted and ridiculed when she attempts to expose Evil Chancellor Lord Orthallen. Her fellow Heralds are at least willing to give her the benefit of the doubt, but Valdemar's councillors are not Heralds and see no reason to believe a girl barely out of training over a man with 20 years of service to the kingdom and enormous personal and political power. Orthallen, in his turn, recognizes Talia's threat to him and sows rumors to cast doubt on her reliability.
 * Justified in Flight as he's a mute.

Video Games
"Shepard: So the geth believed your proof that the Reapers were coming back? Legion: Of course. Shepard: ...That must have been nice."
 * Feizhi from Golden Sun makes many accurate predictions, but her father dismisses them as coincidences. If the player helps her save her friend Hsu, her father finally admits she can tell the future.
 * Commander Shepard from Mass Effect is one as far as the brass is concerned. S/he can't convince them of anything important, no matter how damning the evidence presented is.
 * Most of Shepard's predictions sound absurdly crazy from the perspective of the council or anyone else. The council very quickly changes their mind about  when s/he presented hard evidence. Admittedly, the witness testimony should have been given more weight considering he was identified by name by another Spectre.
 * Gets even more absurd in Mass Effect 2. Where the council(if you kept them alive) STILL doesn't believe you. Despite you having saved them personally from a Reaper. The blame it on the Geth, even if Legion(a geth) is in your party and says "nope, wasn't us."
 * Lampshaded with Legion in Mass Effect 3:


 * Makes sense, actually. Sovereign looked like a Geth ship (since Reapers influenced the Geth) and all of its footsoldiers WERE Geth. As for Legion: Yeah, one random guy says "We didn't do it" and I am going to believe him? Especially since Shepard's judgement was questionable for Mass Effect 2 (working with a known terorrist group, probably hung up on them at least once in ME 1, etc).

Western Animation

 * There is a gypsy moth in the Chip 'n Dale Rescue Rangers episode who predicts a soon and certain end to Chip's life. The Rangers' leader refuses to believe in that prophecy and continues on the case until all details but one have come true. The name of the moth is... Cassandra.
 * Combined with Crying Wolf in Invader Zim, because Dib is almost always right, but it seems like he is wrong because he's always in the wrong place at the wrong time.
 * That, and the fact that the entire world population (except Gaz who doesn't care about Zim because she knows he's an idiot who can do no real damage) are raging idiots.
 * Candace on Phineas and Ferb is constantly trying to prove to her mother that her brothers, the titular Phineas and Ferb, build all kinds of crazy projects in their backyard.
 * Likewise, Vanessa tries to prove to her mother her father is a Mad Scientist, but it always fails, largely because Doctor Doofenshmirtz isn't really good at villainy.
 * Mr. Crocker on The Fairly OddParents knows that Timmy Turner has "FAIRY GODPARENTS!", but everyone thinks he's insane. He is, but he's still right.
 * Travis the head louse in the "Lice Capades" episode of South Park.
 * This is Toxic Crusaders character Psycho in a nutshell: his entire purpose is to point out to Dr. Killemoff how his latest plan can go wrong, usually involving really unlikely circumstances that nevertheless always end up happening and yet Killemoff never listens to him, despite his predictions having always been right.
 * Cassandra herself was a secondary character in the TV series based on Disney's |Hercules. She's very bitter about her lot in life.
 * Coop of Kid vs. Kat constantly tries to warn his town about Kat's evil schemes, only to earn a reputation as both a liar and a lunatic. However, unlike most examples, Coop gradually seems to realize his status as The Cassandra, eventually focusing on simply sabotaging Kat's plans privately instead of warning people about them. Fortunately, he's thrown a bone in the form of his best friend Dennis and his girlfriend Fiona, who are both aware of Kat's actual identity and are happy to help Coop out.

Real Life

 * The Novikov Self-Consistency Principle is a conjecture on Time Travel, which is theoretically possible under some interpretations of general relativity theory. Basically, if any event caused by a time traveler could change the timeline, then the probability of that event happening is zero. Time paradoxes are impossible no matter how much screaming you do.
 * Ron Paul He's just a looney conspiracy theory nut who doesn't understand how things work.
