Selective Obliviousness

""It's not in denial. I'm just very selective about the reality I accept.""

- Calvin, Calvin and Hobbes

""I reject your reality and substitute my own.""

- Paul Bradford, The Dungeonmaster (popularized by Adam Savage, Myth Busters)

When a character refuses to comprehend a particular fact. They'll especially turn it up when someone attempts to tell them directly, which usually results in said would-be confessor aborting the attempt because not only was it a difficult subject to begin with, they can't bring themselves to smash this person's sense of reality.

Regarding unrequited relationships involving someone with Selective Obliviousness; even if everyone else is aware of someone's crush on that person, nobody will ever mention the possibility to the practitioner. Nobody likes to gossip about who is interested in who, especially teenagers.

Stop laughing. This is one person's cross to bear alone.

This contrasts with Weirdness Censor, in which everyone except the main characters is oblivious to the bizarre occurrences around them.

Usually, this is supposed to denote a sense of innocence; however, to more cynical viewers, it may appear that the person either consciously or subconsciously knows, and just doesn't want to deal with it. It also seems inexplicably popular with characters whose main trait is (apparent) perceptiveness of other people's character. Selective Obliviousness is also a tool that the writers use to keep things in the air, such as for Will They or Won't They? or Belligerent Sexual Tension. Like all stalling tactics, overuse breeds contempt.

Less comically, a character may do this to avoid acknowledging his own guilt or envy in some manner. Often leads to Divided We Fall.

If this happens in real life, it is called Canon Discontinuity. That said, No Real Life Examples, Please. Those just cause heated debates.

Plot-Sensitive Snooping Skills is a sort of involuntary Selective Obliviousness imposed on a character by the limits of the plot. Contrast with Failed a Spot Check, in which the character fails to comprehend something everyone else is aware of.

Oblivious to Love, Giftedly Bad, No True Scotsman, and Hypocritical Fandom are common forms of this. See also I'll Pretend I Didn't Hear That, in which a character feigns Selective Obliviousness in order to avoid the consequences of acknowledging the situation.

Anime & Manga

 * Naruto should be the Master of Selective Obliviousness. He refuses to acknowledge that Sasuke has become a sadistic avenger bent on destroying their home village, despite the fact he KNOWS Sasuke has allied to Akatsuki and tried to kill him twice. While Your Mileage May Vary, Naruto is obliviously choosing not to accept the truth and the possibility of killing Sasuke. And if you consider just how much he meddles in other people's dark pasts and feelings, he's really unwilling to accept any other truth or way than his own.
 * It's not that he choose to ignore anything, it's just that killing Sasuke is simply NOT an option for him.
 * And he also chose to ignore his repressed feelings of hatred against the Leaf Village over the abuse he suffered, even AFTER . He's should become God of this trope. It seems it's okay to batter other people for not facing their own issues, but when the shoe is on his foot, he just pretends it didn't happen and it's the right thing to do!
 * How he didn't realize Hinata had strong feelings for him, something many of the other ninja's were easily able to figure out.
 * In Ranma ½, the bombastic Tatewaki "Blue Thunder" Kuno refuses to believe that the hated Ranma Saotome and his beloved "Pigtailed Girl" are one and the same, even when Ranma changes right in his arms. After a while, one wonders if he isn't fully aware and just forcing himself not to think about it. His sister has a similar ailment, but she isn't confronted with the evidence quite as often (and in the anime, never) and actually tried to figure out what happened before getting sidetracked. Kuno might also be purposely ignoring all of the blatant evidence that neither of his "love interests" actually even likes him, let alone lusts after him... although this may be less Selective Obliviousness and more a cocktail of Casanova Wannabe grade lechery (Kuno is debateably a Handsome Lech) and whopping ego.
 * Akane Tendo is often accused of this regarding the fact that her pet pig is actually the cursed form of one of Ranma's rivals for her affections.
 * Hell, Akane Tendo practically lives this trope in both canons. It's got to be the biggest problem she brings to the relationship, even worse than her insecurity. That's not to say that Ranma doesn't contribute his own flaws, faults and problems, but when she's been shown to consciously ignore Ranma's attempts to explain how a situation wasn't what it looked like, to the extent that the manga version of Akane ignored Ranma's outright telling her why he was trying to grope Hinako, coupled with showing her the pressure point chart he was using, in order to support her own belief that it's because Ranma is an uncontrollable lecher... well...
 * To be fair to Akane, some of the situations really do look that bad (naked with Shampoo in the furo in a very suggestive pose for example) and in regards to Hinako, he was practially attacking her several times in her introduction arc, very much coming off like a pervert by grabbing her breasts, and without any explanation, it's doubtful that anyone would believe him.
 * In the anime canon, this flaw is actually the explicit reason why Akane is a Lethal Chef; she refuses to follow the recipe and adds extra ingredients that she believes will make it even better (and then adds the wrong wrong ingredients, due to not looking at what she's grabbing), and refuses to admit her cooking habits are why nobody will ever eat her cooking unless forced. In one episode, she spends the entire night trying to make edible cookies and continues to repeat the same mistakes over and over even though each and every batch turns out terrible. When Ranma finally allows himself to be guilted into eating her latest batch, and promptly takes to his room with severe stomach pains, Akane idly declares that the recipe must have been faulty.
 * Kasumi Tendo calls people who are actively trying to murder Ranma his "friends". Often Flanderized in Fanfic into one of her defining traits.
 * Granted, considering Ranma's training tactics and his talent for annoying people, most of the people who look like they're trying to murder Ranma actually ARE his friends.
 * Mousse could be called Selectively Oblivious in regards to Shampoo. He refuses to admit that the girl he's been chasing since they were three has never shown any sign of reciprocated interest, at best ignoring him and more commonly hitting him whenever he made one of his "romantic" gestures/speeches. By the late manga, she's perfectly willing to let him die just to be rid of him. Instead, Mousse blames her lack of interest on her (willingly given and clearly backed by genuine emotion, at least in the anime) engagement to Ranma and frequently assaults the Japanese boy, accusing him of seducing Shampoo or otherwise keeping her away from Mousse.
 * Revolutionary Girl Utena was interesting in that it didn't portray the girl (Shiori) practicing Selective Obliviousness in a positive light.
 * One can also argue that Utena starts indulging in this after episode 31.
 * In Cromartie High School, no one (except Kamiyama, Hayashida, and the Doctor that preformed the school physicals) seems to notice that Mechazawa is, in fact, a robot.
 * The same for the student gorilla.
 * Kyon of Suzumiya Haruhi very deliberately ignores any hinting that the ; he refuses to acknowledge   as well as Tsuruya's telling him that he and his friends really need to work on their Masquerade better.
 * And then there's just his ignoring Haruhi's feelings for him; over which she's willing to rewrite the whole of reality over. Even Itsuki is starting to get annoyed.
 * And then there's the fans, but that's a different story.
 * Souichi of the Boys Love manga The Tyrant Falls in Love doesn't seem to realize that he's making an awful lot of exceptions to his homophobia in regards to his gay companion Morinaga, not even after he says outright that he doesn't want Morinaga to leave him and that he can have sex with Morinaga only. That must be one hell of a balancing act between "I hate hate homos!" and "I can't let Morinaga leave my side, even if he likes me that way!" in Souichi's mind.
 * Nearly the entire cast of Hayate the Combat Butler has this about one subject or another (Sakuya, for example, believes her destiny is to become Japan's greatest comedienne, with Nagi as her partner).
 * Ouran High School Host Club: Tamaki persistently interprets his attraction to Haruhi as paternal affection; hilarity, naturally, frequently ensues out of the dissonance. Aside from Haruhi herself, no one else is fooled, and in recent volumes the other members of the Host Club speculate that Tamaki subconsciously refuses to acknowledge his feelings for Haruhi because he doesn't want anything to break up the surrogate family he's created in the Host Club the way his parents' love caused his own family to be broken up.
 * Penguin Revolution: It takes Ayaori six manga volumes of rooming together and, finally, actually seeing Yukari naked (with his contacts in, for a change) before he realizes that Yukari is a girl pretending to be a boy instead of a boy pretending to be a girl. Sure, he's Blind Without'Em, but Yukari pretty much stops trying to keep the act up around him before the first volume is over.
 * In Detective Conan Ran has had suspicions about "Conan"'s identity, but not nearly as often as she should have, all things considered.  And somehow, she didn't figure it out.
 * Well, one could argue that she is satisfied for a while when there's a proper explanation. And she does try to trick him more than once. It seems that she kind-of accepted it as a fact by now, but she's waiting for Conan to tell her.
 * What about Heiji? He actually labelled his jealousy,  as a 'leader's concern' for his follower....!
 * There was a Fanfic take on this which suggested that Ran is, in fact, hoping she's wrong because she's Genre Savvy enough to have realized some of the implications of what she had been able to figure out, and would like to avoid going farther.
 * Satou's very much aware of Takagi's affection for her at least relatively early on, and she definitely reciprocates it. What she isn't aware of is how much nearly every other male detective in her department is crushing on her (well, except for Shiratori, but that was only because she got stuck in an omiai with him), to the point where she never seems really aware why the Absolute Defense Line keeps making things difficult for the hapless Takagi. She doesn't even realize that any ring on her left ring finger will typically symbolize engagement! On the other hand, considering that the last officer she was attracted to died at a mad bomber's hands...er, explosives...she may just be subconsciously tuning out anything that could lead her into that sort of devastation again. Takagi's genuine love for her is the only thing capable of getting through that membrane.
 * Misa in Death Note constantly professes to be talented when it comes to romance (and might well be), but constantly refuses to see that her beloved Light actually hates her. Admittedly, he acts otherwise fairly well, but not all the time, resulting in several Kick the Dog moments.
 * It's hard to say he outright hates her, it's more easy to say he's just using her, and she'll accept that. She doesn't realize however he's evil to some extent and not the Knight in Shining Armor she thinks he is, and she doesn't think he's capable of . If he'd hate her, he'd just dispose of her after, but instead gives her the "choice" (more like order) to give up her note for the good of humanity. That's more than the chance he gave any other character close to knowing his secret, including.
 * Actually, according to the thirteenth volume (the guide volume), he does in fact hate Misa almost as much as L, Near, and Mello!
 * For a certain value of "hate".
 * In Axis Powers Hetalia, England doesn't seem to comprehend what colonial America meant by "Go to hell, England". Even in the present, he thinks of how cute of a kid America was.
 * To be fair, that was a very early strip and it seems to have been retconned since then. All the later strips show the relationship between England and little America as genuinely warm and fluffy, with little America pretending to enjoy England's cooking even though it's horrible, being happy to receive presents from England, and crying when England goes home.
 * Spain actually has this moreso than England, especially in the strip where he proposes to Romano. He merely asked for three meals a day without the slightest hinting to either option, but Spain automatically takes it as rejection.
 * America also fits in this, as Word of God states that he "refuses to read the atmopshere". In other words, he can literally choose whether to remain oblivious to an event or finally pay attention to it.
 * Russia seems to think that other nations actually want to live with him. When one of them rebels and he does have to face the fact that they all hate him except for Belarus, he doesn't seem to have a clue why.
 * More recently, Denmark has been hinted to do this as well, ignoring aggressive social behaviour and maintaining a cheery demeanour. He never gets it whenever Norway insults him, and during the 2011 Halloween event, when Belarus throws a hanger at him and declares that Russia's team will win, he simply wished her luck.
 * Then there's Japan's reaction after he and Greece had sex: "IT WAS ALL JUST A DREAM! I'M SO GLAD IT WAS JUST A DREAM!"
 * Sousuke from Full Metal Panic. In the beginning, it looked more like he sincerely never notices when characters are in love with him. However, as the series goes on, it starts becoming more and more obvious (as his suitors become more and more direct) that he's actively turning up his obliviousness. This is no doubt due to his atypical upbringing, he probably has no idea HOW to react to such affection. His relationship with Tessa comes to mind, in particular. Numerous times, she makes incredibly aggressive advances on him, which he actually notices enough to feel nervous and scared. However, when people are later referring to her feelings for him, he's shown to react in a very oblivious manner, many times completely dismissing it.
 * She's his commanding officer. That makes a relationship between them very complicated.
 * Yurika in Martian Successor Nadesico tends to do this, insisting that Akito is head-over-heels in love with her, even though he's never shown any signs of it and tends to get pretty annoyed when she tries to get close to him. But it's possible that her obliviousness is all part of a master plan to make Akito fall in love with her.
 * This is actually a pretty strong plot point in Umineko no Naku Koro ni. Battler refuses to believe that a witch murdered everyone. Straightforward enough. However, he also refuses to believe that any of the eighteen people trapped on the island murdered everyone. Not only does he refuse to believe it, he actively rules out the possibility based on the fact that he doesn't want that to be the outcome, even when he acknowledges that the evidence points in that direction. Can you say "cognitive dissonance"?
 * This being Umineko, the truth of what's going is a bit more... complicated.
 * In Monster, Eva manages to overlook the fact that she had mistreated Tenma in the worst way - and when he tells her, nine years after she had broken off their engagement, that he is flattered but uninterested in reconciling, she chooses to turn a deaf ear and threaten him with telling the police that he had killed her father should he really decide to continue his life without her.
 * In Moyashimon, Aoi Mutou used to work hard at part-time jobs so she and her boyfriend could afford a place together. But one day, she arrived at his apartment only to find he had moved out, taken the money they had saved, and left a note saying he had found someone else. Mutou preferred to believe that he had been abducted by aliens, which is how she fell in with the agricultural university's UFO Club. Any attempts to bring up the obvious truth simply drive her to drink.
 * Clannad: Upon learning that his daughter, Nagisa, Akio is torn between denial , joy and wanting to strangle Tomoya . He does eventually (grudgingly) accept it. This is a rather extreme case, as.
 * Yamamoto Takeshi is the poster boy for this trope. He has seen talking infants wield guns, come very close to dying at least three times, traveled forward in time to stop an Omnicidal Maniac from destroying the world, and still thinks the mafia is an role playing game Tsuna and Gokudera cooked up. After being specifically told this isn't a game multiple times.
 * He takes game seriously though, not selective obliviousness in his case... he is just plain oblivious and idiotic. He definitely no longer think this whole mafia business a game once they transported to future, maybe before that he already was depend on your opinion how serious he was in battle. Hard to say since he smiled in 80% of his fights...
 * Asuka from Neon Genesis Evangelion does it as part of her Belligerent Sexual Tension with Shinji: while she never misses an opportunity to berate his perceived weaknesses and constantly calls him an idiot, pervert, etc., whenever he demonstrates evidence to the contrary, she makes a pointed effort to ignore it due to her severe intimacy issues. This becomes even stronger as the series goes on, eventually contributing to her mental breakdown when she realizes it's not working anymore.
 * Ikuto in Nagasarete Airantou is this to anything supernatural, dismissing it as his imagination or putting it into logical reason, despite living on a daily basis with talking animals and a kappa.
 * In Skip Beat, Kyouka is completely oblivious to the fact that Ren is in love with her, even after his assistant blatantly told her.
 * Though she does have a Freudian Excuse, as after the guy she was in love with pretty much admitted he only saw her as free labor, her feelings of love died.
 * As a Running Gag in Eyeshield 21, Mamori continiously misses the signs that Sena is Eyeshield 21, despite Sena practically Clark Kenting. She knows Sena has the same build as Eyeshield 21, that Sena joined the football club, never saw Eyeshield 21 without his mask and Sena always seems to disappear when Eyeshield 21 shows up. She thinks "Everytime Eyeshield 21 shows up... Sena never seems to be around. Maybe they... don't get along well?" The justification is that since she still sees Sena as a little kid who cannot stand up for himself, she simply cannot think of him as a successful football player. It's even lampshaded by Hiruma: "Preconceptions are harsh..."

Comic Books

 * Can be seen in Western depictions of a Superhero with a secret identity, attempting to tell it to the loved one. (Example: Spider-Man's Aunt May.) One Superman story has Lois admonishing the Man of Steel for "that creepy Clark Kent impersonation." (Indeed, one might make a claim that the whole Superman mythos embodies this trope, as it would seem painfully obvious that Superman is just Clark Kent without glasses.)
 * In the 2000s, Aunt May found out Pete was Spider-Man, and called him out on not telling her, pointing out that she had survived the death of his parents and Uncle Ben. She also said that for a while, she had thought he was gay. Peter burst into laughter.
 * J. Jonah Jameson generally frowns upon "costumed vigilantes", considering them usurpers of law and order. But he is willing to give the devil his due when it comes to true acts of heroism and is considerably lighter on those he feels have "paid their due" - like Captain America. Of course, there is a big Spider-Man-shaped blind spot in this P.O.V. - which, Depending on the Writer, can range in severity from Running Gag (Robbie Robertson constantly having to talk Jonah down from some of his more libelous headlines and editorials) to outright insanity (the newly-elected mayor of NYC Jameson gleefully watching a S.W.A.T. team open fire on Spidey without provocation.)
 * It's implied that, if Commissioner Gordon wanted to, he could figure out Batman's identity, but he deliberately chooses not to, and has in fact refused to look when Batman offered to reveal who he really was.
 * In Batman Year One, he's standing two feet away from Batman who, out of costume, just saved his infant son's life and hands him the child. Gordon blames the loss of his glasses for his inability to recognize the man...even though it's blatantly obvious that Gordon knows it's Bruce Wayne, and his lame excuse is his way of allowing them both to walk away without acknowledging the fact.
 * It's painfully obvious that Doctor Doom, being a supergenius and all, should be able to realize that Reed Richards had crap-all to do with the malfunction that caused Doom's experiment to blow up in Doom's face, and was only trying to explain to Doom that the experiment was flawed. However, Doom apparently can't stand the idea of Reed being smarter than him, so he steadfastly refuses to see reason and continues to try to destroy Reed's life in "revenge". It's hinted he does know this full well deep down though, as whenever Reed calls him out on this bullshit, he tends to fly into a homicidal rage, and at least once started beating Reed into a bloody pulp while screaming at him to admit he sabotaged the experiment "or else!"
 * Like with Doom above, Loki has this problem, though some of it does depend on how sympathetically he's being portrayed. While many writers acknowledge that Loki was The Unfavorite, how much of the is his own fault varies/
 * Also, Loki often claims things like "everyone hated me" which may or may not be true. While most of Asgard does indeed dislike him, Thor himself foten references that he and Loki were happy together as children, and Loki just seems to block that time out so his Freudian Excuse is more credible.
 * Now Loki's back at that childhood age, with only those memories, and guess what? He's happy and knows that Thor loves him like the little brother he is and cares for Thor in return He also doesn't get why everyone seems to hate him since he doesn't remember all the things he did as an adult, which lends credence to the idea that Loki was editing his own self history to make it so he was "always hated" so his excuse held up.
 * Now he does know, since many people of Asgard were nice enough to point it out for him that his scheme led to The Sentry bringing Asgard crashing down. However, they are also unwilling to tell him almost anyuthing else (like who people are, what is happening at the moment, etc), since they still want to off him the second they think Thor won't care. The only exceptions so far seem to be the Warriors Three, who seem to do so very grudgingly (unless the story is funny or makes who Loki used to be look bad).

Fan Fiction

 * Kyon's mother in Kyon: Big Damn Hero refuses to acknowledge that Kyon had to get into a fight because of Tsuruya when she is told that Kyon had to replace Tsuruya's bodyguard, and instead decides to be full Shipper on Deck between them. And that was after scolding him for getting info fights at school (which happened because of Tsuruya too).

Film
"Daphne: Well ... in the first place, I'm not a natural blonde. Osgood: Doesn't matter. Daphne: I smoke! I smoke all the time! Osgood: I don't care. Daphne: I have a terrible past! For three years now, I've been living with a saxophone player! Osgood: I forgive you. Daphne: (tearfully) I can never have children. Osgood: We can adopt some. Daphne: You don't understand, Osgood ... (ripping off wig) I'm a man! Osgood: Well, nobody's perfect."
 * Mars Attacks!!. Art Land is so intent about selling the investors on building his casino that he ignores the all out alien attack going on outside.
 * A creepy example in Shutter Island. An asylum inmate subconsciously created an elaborate illusion of residing in her neighborhood, and treated other patients and staff as neighbors or delivery men, flatly refused to admit that she's been committed for murdering her children. Then the unfolding story reveals that  In fact,
 * In Some Like It Hot, Jack Lemmon, masquerading as "Daphne", gets a marriage proposal from Osgood, an elderly millionaire. Daphne tries to talk him out of it:


 * This is what the title of An Inconvenient Truth refers to (specifically, being unwilling to observe something because your job depends on you not observing it).

Literature
"The mind should develop a blind spot whenever a dangerous thought presented itself. The process should be automatic, instinctive. Crimestop, they called it in Newspeak."
 * In The Hitchhiker's Guide To The Galaxy (at least the novels), Zaphod is literally selectively aware of his own motives,
 * This is also in the movie. It's more of a Hand Wave of Zaphod's two heads because they don't go into specifics.
 * Mostly Harmless features a species of bird that is oblivious to every strange thing that happens, like ignoring a fiery spaceship crash. However, they are always shocked by perfectly mundane things. For example, "...And sunrise always took them completely by surprise."
 * Their train of logic is that an unusual thing only happens once, so it's not worth noticing, as it'll probably not affect them. On the other hand, something that happens every day will affect them, so it's worth noticing.
 * Clifford manages to be shocked when he finally learns that his wife has been having an affair with another man in Lady Chatterley's Lover. His maid recognizes that he subconsciously knew about his wife's infidelity from the start, but just didn't have the courage to face it.
 * In Discworld, Twoflower is besotted with the idea of Rincewind as a Great Wizzard (sic), and refuses to realize that he's completely incapable of doing magic. This is far more prominent in Interesting Times, though, as he does seem to exhibit something approaching realization in The Colour Of Magic.
 * Also in the same series, the Duck Man refuses to realize that he has a duck on his head, regardless of how many people tell him so in no uncertain terms. This is more Rule of Funny, though.
 * Lord Rust is also well known for, as the author puts it, "Erasing unwelcome sights and sounds from his personal universe". This causes problems for him when people like Detritus and the Dean of Unseen University are apparently too large to erase, and hilarity when Vimes takes advantage of it to swear at him without him noticing.
 * In Making Money, Mr Bent prides himself on his impeccable perception and eye for detail (he can spot a miscalculation with just a glance from across the room) but is oblivious to a female coworker's open infatuation with him. Presumably it's not so much self-denial as it is an inability to expect anyone to have those feelings for him.
 * In The Secret History, Julian knows every important part of the plot, except for the crucial fact that five of his students killed the sixth one. He wants to believe the best of them, but really, it's not a huge leap to make...
 * Early on in Quills Window, Courtney Thane's mother writes to him that she genuinely has no idea why his father cut him out of the will right before he died, and Courtney's sentiment seems to be the same. When we find out the reason for this later in the book, it becomes quite obvious that if either of them had engaged in serious self-reflection they would know the reason behind the father's I Have No Son moment.
 * This is the cornerstone of Nineteen Eighty-Four's Doublethink. Bonus points for the requirement that obliviousness must not only be selective but also instantly switchable -- you must completely and sincerely forget whatever you vehemently believed in a moment ago and, if necessary, switch back the next moment -- and recursive -- you must forget that you've just forgotten something, forget having forgotten that, et cetera.

"He set to work to exercise himself in crimestop. He presented himself with propositions -- 'the Party says the earth is flat', 'the party says that ice is heavier than water' -- and trained himself in not seeing or not understanding the arguments that contradicted them."

"Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity."


 * Johnnie Rico in Starship Troopers. While he tries hard to paint himself as "just another ape", reading between the lines shows he's pegged as leadership material almost from the start.
 * A short story (author, title forgotten) from the 1950s or 60s has a space traveler land on a planet. He encounters a village with two populations, where persons of one population are oblivious to anyone in the other. They dress very differently, so the main character can distinguish between the two. Representatives of both populations see him, because his dress is ambiguous. There is at least one hint that the obliviousness is pretended: The main character resolves the issue
 * The Ministry of Magic in Harry Potter choose not to believe that Voldemort is back in Harry Potter and The Order of The Phoenix despite the overwhelming evidence. They lead the public to believe that all is well and constantly berate Harry and Dumbledore as liars. It's explained that they have a contrived denial caused from how horrible Voldemort's previous reign of terror was. Despite this explanation, many fans interpreted them as Too Dumb to Live.
 * In Book 4 it's briefly mentioned that Petunia, who could spot the tiniest imperfections that could be used for gossip fodder, refused to see that Dudley's obesity had reached dangerous levels (in the book he's compared to a young killer whale). She only sees reason after the Dudley's school nurse sends her a letter about it since the school doesn't stock uniforms in Dudley's size.
 * Given that by the next book he has lost all the extra weight and is an accomplished boxer, they must have had a fairly limited selection (or he had an inhuman metabolism).
 * For the whole year, Dudley had been eating what essentially amounted to a couple of grapefruit a day, and with the exercise that came from boxing, he would've lost enough weight to make an anorexic proud.
 * In the Jin Yong novel Smiling Proud Wanderer Linghu Chong, despite usually being quite perceptive and it becoming glaringly obvious, cannot grasp that his master is a scheming coward who doesn't care one bit for either Linghu Chong or any other of his pupil.
 * The residents of Valdemar have a  blind spot when it comes to the existence of magic and the true nature of their Companions. For example, the scholars of Valdemar insist that the ballad of Kerowyn's ride, an account of more or less contemporary events, is meant to be interpreted metaphorically even after the real Kerowyn shows up in Valdemar and becomes one of the Queen's best-known advisors.
 * In The City and the City by China Miéville, two European cities, Besźel and Ul Qoma, exist on the same spot at the same time, interwoven with each other. Citizens of one city are trained from a young age to "unsee" the other city and its citizens, under dire penalty from a peacekeeping force known as the Breachers.

Live-Action TV
"Tobias: You know, Mother Lucille, there's a psychological concept known as 'denial' that I think you're evincing. It's when a thought is so hateful that the mind literally rejects it. Lucille: You are a worse psychiatrist than you are a son-in-law, and you will never get work as an actor because you have no talent. Tobias: Well, if she's not going to say anything, I certainly can't help her."
 * Sent up in (what else?) Arrested Development:

"Sgt Shultz: I see nothing. NOTHING!"
 * Rachel of Friends is in constant denial about her true feelings for Ross when she's not with him. On the day before Ross's wedding to Emily, she somehow finally figures it out: "Sure, I like Ross, but feelings are really complicated... maybe I am sexually attracted to him, but I do love him... oh my God." When she demands of Phoebe on why she didn't tell her about her own feelings before, Phoebe replies, "Well, it's so obvious to everybody. It's like saying, 'Gosh Monica, you sure like to clean.'"
 * Chandler asks for no strippers at his bachelor party, and after he leaves Joey immediately asks what kind of strippers they should get. Ross reminds him what just happened, and he replies "Huh. I chose not to hear that."
 * The Colbert Report: Stephen Colbert insists that he is completely straight. Evidence to the contrary is dismissed with convoluted excuses when possible, ignored when not (as with the diagram of his brain in which one area was labeled "Repressed Homosexual Urges").
 * Gul Dukat on Star Trek: Deep Space Nine. His imagined friendship with Captain Sisko escalates to ridiculous levels throughout the series, to the point where he chides Sisko for being so obtuse about his feelings while on the opposite sides of a battle line or in the middle of a no-holds-barred hand-to-hand fight. In fact, you could probably form a whole section on all the things Dukat pointedly ignores. (Although, from what little has been revealed of the Cardassians, that may be how they express friendship, or he may be doing it just to annoy Sisko.)
 * Hogan's Heroes:

"The Doctor: Oh! I know what it's like. It's like when you fancy someone and they don't even know you exist. That's what it's like. (runs off) Martha: (stares despairingly after him) Captain Jack: You too, huh?"
 * In Strangers with Candy, the homophobic Principal Blackman is the only one who doesn't know that Chuck and Geoffrey are lovers. At one point he catches them in the school basement and happily accepts the explanation that Chuck is showing Geoffrey the furnace system, even though Geoffrey has his trousers round his ankles.
 * In Lie to Me, Gillian readily accepts her husband's feeble excuses about having to work late, even though her job is based around the ability to tell instantly when someone is lying.
 * On Angel Wesley managed to be totally oblivious to Fred's feelings for him in Season Five. This came to a head in an episode when he lectured Angel about the latter's failure to notice Nina's interest, while himself remaining totally unaware of Fred's. She eventually resorted to a Forceful Kiss to get the message across.
 * In Season Three, Cordelia was this way about Angel's feelings for her. Fred seemed to be likewise re: Wesley's feelings for her, until Gunn later casually mentioned that she knew about them.
 * Barney Stinson from How I Met Your Mother is almost totally self deluded, not only is he a compulsive liar who believes his own lies, he constantly twists his perception of reality to paint himself and his life as "awesome", no matter how pathetic he actually is. For example, he will invent arbitrary social rules to justify his behaviour and claim historical precedents for them, and continualy insist they are true, despite their obvious falsehood.
 * This is apparently because, when he was a child, Barney's mother chose to lie to Barney and conceal from him anything that might damage his sense of self worth, for example, when no-one came to his birthday party, she forged a letter from the Postmaster General, claiming he had lost all the invitations. This made Barney unable to accept anything that might damage his overinflated ego, once, when he amiably broke up with the bar's waitress, he chose to believe she had gone crazy and was trying to murder him, rather than face the fact she simply didn't mind not being with him
 * Everything you need to know about Barney can be seen in an episode in the sixth season, Zoe sets Ted up with her attractive cousin "Honey", and Robin and Barney both relate their own versions of the date to Marshall; in Robin's presumably more truthful account, Honey is fascinated by Ted and blatantly flirts with him, while Batney desperately attempts to hit on her and she politely ignores him, while Barney does leave with her, it's only because Ted is much more interested in Zoe and lets him; in Barney's version, Ted bores Honey by droning endlessly aout architecture, and she is virtually ripping off Barney's clothes the whole time. When Marshall points out the difference in the accounts, Barney angrily insists his is true
 * Played with in Hannah Montana, Miley mentions that she's kissed, and quickly backpedals prompting Robbie Ray to say "I love our relationship, you pretend you don't kiss boys, and I pretend I believe you"
 * In The Mighty Boosh, whenever Vince says or does something suggestive towards Howard (which is quite often) Howard will either walk away or awkwardly change the subject, totally ignoring it
 * Doctor Who: The Doctor about Martha's feelings for him during Season Twenty-Nine. "It's right in front of me and I can't see it" indeed.
 * Martha and Captain Jack Harkness both, apparently:


 * Though, it wasn't as if Jack was ever unclear in his flirting with the Doctor; and Martha wasn't exactly subtle about her frustration either. The above quote was the moment when the Doctor finally admitted that he knows, but always ignored it, because he's too much of a coward to talk about it directly and tell Martha that he's not into her that way. This was him saying "Get a hint already!" It's all in the delivery of the line and the pointed look at Martha. Jack's commiseration wasn't about the Doctor being oblivious, but about them both crushing on the guy even though the Doctor doesn't feel the same way.
 * Guy of Gisborne from Robin Hood chooses to ignore the mounting evidence that Marian is in cahoots with Robin Hood. By the final episodes of season two, he's in complete denial.
 * A very common theme in Hoarders, where people don't seem to notice they're living in squalor. One episode featured a woman who had a lot of dolls. At one point she picks up a small doll that's the size of a soda can and declares that it doesn't take up any space, completely ignoring the 8-foot-tall mountain of toys in front of her.

Newspaper Comics

 * As demonstrated by the page quote, Calvin and Hobbes' Calvin.
 * Krazy Kat, convinced that the psychopathic mouse who throws bricks at his head every day does so only as a sign of undying love. When Officer Pupp arrives to nab Ignatz for his crimes and toss him in jail, Krazy just thinks they're playing tag, like the good friends that they are.

Tabletop Games

 * The beholders in D&D are like this by design. They have two brains. One is responsible for higher logic. The other hosts emotions and instincts, and is responsible for interpreting the data input from the senses. Thus, if something is against the beholder's beliefs, it will never get far enough to be considered on logical level. Too bad their genetic memory gives them the beliefs of rampant, murderous racists. The only reason they manage to survive at all with such a mindset is that their creator have also found it fitting to grant them innate massive firepower.

Theater

 * Cyrano De Bergerac:
 * At Act I Scene IV, Cyrano fails to notice that the buffet-girl is a Smitten Teenage Girl with him. He is so convinced he cannot be loved, that Le Bret must point out to him this fact (see Oblivious to Love).
 * At Act II Scene III to IV, it seems that Ragueneau fails to notice that his friends, the poets, are with him only to eat his pastries and that his wife is having an affair with a mousketter. He knows the truth about the poets (see Establishing Character Moment), but refuses to acknowledge Lisa’s infidelity.
 * At Act II, Scene V, Cyrano bribes Roxane’s Duenna to leave them both alone at Ragueneau’s bakery, and greets Roxane with a I Can't Believe a Guy Like You Would Notice Me Stock Phrase… that she doesn’t catch… at all, because Cyrano is a Unlucky Childhood Friend whom Roxane considers like a brother. And from here, It Got Worse: Roxana will never catch any clue for years.

Video Games

 * In Prototype soldiers will react at the display of the protagonist's Lovecraftian Superpowers or explicit hostility but super-fast runs, super-high jumps, running up a wall or falling from the sky and punching a crater in the pavement will be ignored.
 * Justified in a Fridge Brilliance manner because the protagonist can slaughter them without thinking about it, and most soldiers would rather keep on living.
 * And the game wouldn't be very fun if you couldn't move around without being attacked.
 * Role-players in City of Heroes (and presumably other games) almost require this trope for certain scenarios to take place. For example, there's certain to be more than one (or more than fifty) characters running around who all claim to be the same specific character from mythology (popular examples include Thor, the Devil, and even Santa Claus). If one accepted that all these characters' stories are true, even though they clearly contradict each other, they'd go insane.
 * Also tends to be a vital tactic in other areas of roleplay: text-based combat (rather than in-engine PVP) often times breaks down into "Bang bang! / OH I dodged! / No, I shot you / no you didn't!" levels of quarrels; Selective Obliviousness is oftentimes the only way to resolve a situation before ending up needing to get mods involved.
 * Arguably, Harvey Moiseiwitsch Volodarskii from No More Heroes suffers from this in his exit cutscene; he's blinded by Travis' beam katana... And he yells about it being dark.

Visual Novels

 * Masayuki refuses to see the bad in people in A Profile or to distrust his friends. He simply won't notice such things.
 * Reiji actually does realize how Kyoko feels in Kara no Shoujo. He just thinks it wouldn't be right to start a relationship with her.
 * Shirou in Fate/stay night seems to have a slight awareness of Sakura's interest in him, but considering he's in denial about his own attraction to her, she's made nearly no progress in over a year and a half of trying.
 * Junichi in Da Capo is actually perfectly aware that Nemu likes him and has for years. He wasn't just completely dense. On the other hand, she's his adopted sister, which makes things kind of awkward, so he simply did his best not to think about it.

Webcomics

 * In 8-Bit Theater, Thief constantly denies the existence of dragons. Despite the Light Warrior's direct interaction with several of the mythic lizards, Thief maintains that dragons are extinct. When Red Mage calls him out on it in a later strip while they are being confronted by more dragons, Thief explains that it's "wishful thinking". He just wishes the horrible lizard monsters trying to kill him don't really exist.
 * In El Goonish Shive, Melissa is so madly in love with Justin, she keeps asking him out even after it is revealed that he is gay. Justin, needless to say, finds this extremely irritating, especially since she is the one who (either directly or "indirectly") blew the secret.
 * In her case it might be worse than that: in a strip she even stated that "he's just going through a phase".
 * However, in a later strip (after Melissa started becoming a more prominent character), it's indicated that Melissa is fully aware that a romantic relationship with Justin is a lost cause, but can't seem to stop herself without a friend around to snap her out of it.
 * Earlier in the series (though chronologically after Justin was outed), Elliot pretended not to notice Sarah's feelings towards him, because he was afraid that a romantic relationship with her would destroy their friendship; he may have had Justin and Melissa's ruined friendship in mind, since he'd known Justin for some time at that point.
 * In Fans, club president Rikk is utterly oblivious to fellow member Rumy's painfully obvious attraction to him. When third member Katherine gets fed up with this and tries to inform him directly, he exhausts every other member in the club, Katherine included, as potentially having a crush on him. Not once does he even consider Rumy.
 * In Flipside, Blithe Spirit Maytag has a complete and utter lack of any sense of modesty . And an equally complete and utter lack of understanding it in other people. To the point where she's openly baffled when everyone else is upset when their carriage driver is caught using x-ray specs to peep through their clothes. Given the grasp of human nature she shows when she's in Manipulative Bitch mode, this is almost certainly self-justification for her own exhibitionist ways.
 * Van Von Hunter is sworn to destroy anything evil that he encounters. However, he "doesn't notice" that Ariana Rael, the Child Mage tagging along with him is ungodly evil. The fact that she could destroy him with a thought has nothing to do with why he's not picking a fight with her...
 * In Misfile, Doctor Upton can hardly have failed to have noticed that his "daughter" appears to have developed some rather severe identity problems, especially considering that it was shouted out at full volume at one point. Despite this, the issue is never raised.
 * Randy, the tame fox in Faux Pas, is so naive about sex that it's impossible to think this trope isn't going on. This alternately frustrates and amuses the wild vixen who wants to be his mate.
 * In Girls with Slingshots, a Running Gag has been made of Hazel's inability to grasp that lesbian sex isn't just "taking turns with a strap-on." Her lesbian friends have tried to clue her in, but it never seems to stick.

Web Original

 * In Red vs. Blue Reconstruction, Sarge is unable to understand that Grif is now the same rank as him. Grif actually suggests that he is physically incapable of comprehending that fact.
 * The Nostalgia Critic is extremely good at denial over things he doesn't want to admit are happening, only reacting when they're explicitly pointed out to him. His Distaff Counterpart, The Nostalgia Chick, is exactly the same.

Western Animation
"Peggy: Let's see there's the popular kids, the jocks, the nerds, and then there's us. Helga: Hey don't lump me in with you losers. I am accepted by all groups. Hi Debbie, hi Debbie, hi Debbie, hi Debbie, hi Debbie, hi Debbie.
 * In King of the Hill, despite his rampant paranoia and suspicion of everyone and everything, Dale Gribble is completely unaware that his wife is having an affair, although it's obvious to everyone else -- with the exceptions of Joseph, "his" son, and Peggy (who gets clue-by-four'd later on). Nobody has the heart to tell him about it.
 * That's because despite his paranoia, he trusts those closest to him -- his friends, family, and neighbors -- implicitly. And because of how he'd react if he ever found out two of his closest friends betrayed him. He's equally oblivious to his father's homosexuality for much the same reasons.
 * One episode reveals he thought John Redcorn was gay; he does eventually confront the fact that Joseph can't be his son, but comes up with a story involving aliens to explain how he really is.
 * Invader Zim has two cases: Zim, who refuses to acknowledge that his leaders would like nothing more than his swift and painful death, and Dib, who thinks that exposing Zim as an alien will change how his family and peers think of him, despite plenty of evidence to the contrary.
 * Panini from Chowder doesn't understand the meaning of the words "I'm not your boyfriend."
 * Mr. Herriman can spot the tiniest speck of dirt, but he couldn't tell a crudely made decoy of Eduardo from the real Eduardo.
 * On Total Drama World Tour, Cody. Courtney a bit too, though she was at least suspicious that Duncan was cheating with Gwen behind her back; when Cody found out he seemed completely shocked, despite the fact that in-universe it's been a common theory they liked each other going back to season two.
 * In The Oblongs, Helga Phugly thinks she is loved by all, especially the Debbies.

The Debbies: Ewww!"

"Helga: I’m sure my invitation got lost in the mail. Milo: You live in a fantasy world, don’t you Helga? Helga: What was that? I was thinking about my hundreds and hundreds of boyfriends."
 * Regarding a tea party with the Debbies:

"Teacher: Notice anything unusual in these pictures? Lois: You're right, his father isn't in any of them!"
 * SpongeBob SquarePants--in perhaps his greatest moment of stupidity--not only completly ignores the words of warning a gypsy woman gives him about the Gremlins-like creatures she sells, but also ignores when it turns into a massive killer eel in favour of chastising Gary for 'bullying the creature' even when he is in its mouth and about to be eaten.
 * In one episode of Family Guy, Lois' brother, Patrick, is revealed to be the fat man serial killer. Lois refuses to believe Patrick is the killer, despite the several glaring pieces of evidence that point to Patrick until Lois sees more and more damming evidence piling up and Brian screaming at her to wake up.
 * In the episode "The Courtship of Stewie's Father", Lois meets with Stewie's preschool teacher and she shows Lois several drawings Stewie made, which show Stewie killing Lois in horrible ways. The two women then have this exchange regarding the images:

Real Life

 * This is frighteningly true in real life. In research, this is called "confirmation bias", the tendency to only acknowledge the facts that prove you right, and it is THE NUMBER ONE ENEMY of the scientific method.
 * This is why both sides of highly polarized scientific debates tend to think that their opposition has to be crazy to ignore the big neon signs telling them exactly how wrong they are.
 * Climate Change is the best examples: there have been many, many wild accusations from both both sides that their opposition is willfully ignoring contradictory research to keep the cash flowing. In truth, both sides have set up such large strawmen concerning the others that true debate is now literally impossible, and anyone who attempts to bridge the gap, especially from the IPCC side, is seen as a traitor.
 * This is how conspiracy theories stay alive. Any child with a camera can blow apart the moon landing hoax arguments, but that does not stop people from believing that Neil Armstrong was an actor in Area 51.
