This is a particular instance where -- frequently during a discovery of great scientific or historical significance -- the resident MrExposition, whose TechnoBabble has been extremely convincing (and perhaps even accurate) thus far, suddenly makes some comment that is so JustForFun/{{egregious}}ly [[EpicFail off-the-scale of inaccuracy that anyone with a cursory knowledge of the subject realizes the writers]] made the whole thing up.

Many of these will be {{Disaster Movie}}s or Action Movies and will [[JustHereForGodzilla use state of the art computer effects to keep your interest]].

This can be PlayedForLaughs by having a BookDumb character make such an error so that a smarter character can spot and react to it. Compare InsaneTrollLogic.

Contrast the MST3KMantra, which tells us not to worry about these little details. Also see DidntThinkThisThrough, which is less about research failure and more about planning failure. Also contrast AccidentallyAccurate, which is when non-experts think the creators are wrong, but experts know the creators are right--[[RightForTheWrongReasons by complete accident]]. Also contrast LikeRealityUnlessNoted, where what appears to be a research failure can be written off as the result of an AlternateHistory or AlternateUniverse.

''Note: Like other pages related to factual inaccuracy, make sure that your example really is an example. This trope is about errors that are obvious to any grown individual with a high school education and/or a cursory knowledge of the subject. If you feel the need to explain why the person has made an error (and it's not some character getting an in-universe fact wrong) then it is not this trope.''

[[folder:Advertising]]
* A TV spot for the film ''Gamer'' became an Internet hit when it claimed that "the last time Creator/GerardButler kicked this much ass was 300 years ago." Yeah, we're pretty sure they missed a comma there.[[note]]Amusingly, Gerard Butler has done quite a few other historical epics and at least one time travel story... covering damn near every period ''but'' the early 18th century.[[/note]]
* A commercial for Oscar Meyer Franks has a father come home and see his three kids on those electronic gizmos kids use these days. Wanting to spend Quality Family Time, he trips the circuit breaker of his house, knocking the power out and shutting off the older brother's computer, the younger brother's game console, and the sister's '''cell phone'''.
* A 2014 American Family Insurance Teen Safe Driver radio advertisement features two characters that desire to go to "the mall" as their third friend just got her license. In 47 States and the District of Columbia, newly-licensed teen drivers are prohibited from carrying more than zero or one underage passengers for a specified amount of time, usually around six to twelve months. This is an error that would be obvious to young people, but probably not to the people who wrote the ads, who probably got their first licenses under a much less restrictive regime.

[[folder:Anime & Manga]]
* One scene in ''Manga/BakiTheGrappler'' involved a character who blinded people by pulling out their optic nerves... by sticking a finger into the side of his opponent's ''neck'' and pulling said nerve out. The optic nerve, which connects the eye and brain via a hole through the eye socket, really has no business being there.
[[/folder]]

[[folder:Comic Books]]
* ''Comicbook/{{Marville}}'' begins [[AuthorTract a descent into utter madness]] starting in the third issue that includes, among many, MANY other offenses, the protagonists scooping up some water with microbes in it to use as a "biological clock" for their time machine, under the logic that ''they'll know to stop when the microbes evolve into a dinosaur''. It just gets worse from there.
* Franchise/{{Superman}} once [[WritersCannotDoMath multiplied 10x20x16 and got 32,000]]. That wasn't just math, it was ''[[http://www.superdickery.com/index.php?option=com_content&view=article&id=676 Super Mathematics]]''.
* ''Franchise/{{Tintin}}'': Hergé was famous for his research, but made a serious error in ''Tintin and the Temple Of The Sun'': The Incas, with all their astronomical research, would have understood that a solar eclipse is not permanent. Hergé later regretted this scene and always wanted to correct it.
* The original authors of ''ComicBook/{{WITCH}}'' intended to set the series somewhere in America. This is obvious to an Italian, but they didn't bother to go and look on how an American city actually looks like, [[WhereTheHellIsSpringfield resulting in Americans and non-Europeans in general to wonder in which]] ''[[WhereTheHellIsSpringfield European]]'' [[WhereTheHellIsSpringfield country Heatherfield is]]. {{Subverted|Trope}} by the cartoon version: in spite of being made in France, the staff of the animated series ''did'' do the research, and Heatherfield is recognizable as an American town.
[[/folder]]

[[folder:Fan Works]]
* In ''Fanfic/MoonDaughter'', the author classifies dryads and satyrs as monsters. Also, [[MarySue Flavia]] claims that Literature/{{Percy Jackson|AndTheOlympians}} killed Luke.
* Occurs in-universe in ''Fanfic/QueenOfAllOni'' with Lung. Not only did his EvilPlan revolve around the stubborn as a mule Jade submitting to his will, he clearly has no idea about the curse that only allows her to summon her CoDragons.
* Dakari-King Mykan gets the most basic facts about ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' wrong in ''Fanfic/MyLittleUnicorn''. The author believes Rainbow Dash has magic, doesn't know who Derpy Hooves is.
* In the epic-length ''Buffy the Vampire Slayer'' fan fic ''[[http://fanfiction.tenhawkpresents.com/viewstory.php?sid=338 The Road Back]]'', al-Queda expands its September 11th attacks to include other locations around the country. One of the new locations is [[DisneyThemeParks Walt Disney World]] in Orlando. In the story, an al-Queda terrorist drives a truck loaded with explosives up to one of the Magic Kingdom's entrances and detonates it, killing hundreds of people and destroying millions of dollars in property. The problem is, it is physically impossible to drive to the entrance of the Magic Kingdom. Physically impossible. To get to the entrance of the Magic Kingdom, one needs to use a boat, one of the monorail trains, or walk. At most, the bomb would have destroyed part of a parking lot. Now, had the terrorists targeted one of the Magic Kingdon resort hotels, then things would have been different.
* In ''Fanfic/SakiAfterStory'', the mahjong games in the tournament are presented as one-on-one, rather than four-player games. Additionally, the last match of the tournament is Saki against Teru, while in canon, Saki is the captain and Teru is the vanguard, meaning that Teru would face Yuuki, while Saki would face Awai.
* The author of ''WebAnimation/{{RWBY}}'' fic ''[[https://www.fanfiction.net/s/10154960/1/She-couldn-t-understand She couldn't understand]]'' admits to never having watched the series. And it shows.
-->'''Fic!Blake:''' ''(to Adam, a mass murderer of civilians in canon)'' I've always been selfish, while you're selfless.
* From a ''Series/{{Supernatural}}'' fanfic: "At the next intersection, Dean turns left, [[http://community.livejournal.com/fanficrants/9652102.html heading south into the setting sun."]] (Which would only work if he were driving right on top of the north pole.)
* In ''FanFic/SylviaTheSylveon'', the main character is forcibly evolved with an item, but it's revealed in the games that Eevee evolve into Sylveon by Pokemon-Amie and knowing a fairy type more. This is justified in that the story started in February 2013, and Sylveon's actual means of evolution weren't revealed until the games came out in October of that year. The author acknowledges this mistake in the epilogue notes.

[[folder:Animated Film]]
* ''WesternAnimation/FreeBirds'' involves delivery [[ProductPlacement Chuck E Cheese pizza]] as a plot device. Anybody who knows the first thing about the restaurant is that they do not, and never have, delivered pizza, which is served exclusively for the restaurant.
[[/folder]]

[[folder:Live-Action Film]]
* ''Film/TheAmazingColossalMan'' features a ''scientist'' who claims that "the heart is made up of a single cell."
* The {{tagline}} of the film ''Film/{{Biggles}}'' is "Meet Jim Ferguson. He lived a daring double-life with one foot in the 20th century and the other in UsefulNotes/WorldWarI." World War I happened in the 20th century.
* The ''[=MST3K=]''-featured film ''Film/DevilFish'' has a rather infuriating example when a character who is supposed to be an expert is playing a slideshow of prehistoric marine life - mostly animals contemporaneous to, or even predating, the dinosaurs. We're then told they lived in the "Cetaceous" period (pronounced like 'cetacean'), which was two hundred years ago. Not two hundred million. Two hundred.
* A minor but rather jarring moment from the otherwise quite good ''Film/DrNo''. When the script reads, "That's a Smith & Wesson, and you've had your six!", it's probably a good idea to make sure the man Bond is saying this to is holding a ''revolver''. Not a Colt M1911, one of the most recognisable ''semi-automatic pistols'' ever made and which almost everyone knows has a ''seven'' round magazine.
* ''Flight Of The Living Dead'' has a zombie outbreak caused by a mutated malaria virus. This is the disease equivalent of mistaking a house plant for a jaguar: malaria is caused by a parasitic ''protozoan'' in the bloodstream.
* For all the good things we can say about the [[Film/{{Gojira}} Japanese cut]] of the first ''Franchise/{{Godzilla}}'', it's still got a pretty glaring one of these when Prof. Yamane says that dinosaurs lived 2 million years ago, when any child could tell you that they went extinct 65 million years ago.
* In ''Film/{{Hitman}}'', 47 meets with an arms dealer under a false identity. When his cover is secretly blown, the dealer attempts to intimidate 47 by showing off some of his weapons and even threatening to kill one of his prostitutes with a pistol. In so doing he misidentifies aspects of every gun he picks up (such as calling an [=M4A1=] Assault Rifle with an M203 Under Barrel Grenade Launcher as an "M203 with under barrel grenade launcher").
* In ''Film/TheMatrix'' Morpheus's exposition that people are kept in suspended animation because they were [[spoiler:needed as batteries for the machines]] is such an egregious violation of the Second Law of Thermodynamics that it makes everyone with just a cursory knowledge of physics groan. The original treatment had the brains of humans used as sub-processors, which is at least defensible, but thought to be [[ViewersAreMorons too complicated]] for moviegoers.
* Creator/TheAsylum movie ''Film/MegaFault''. The premise is that a giant earthquake opens a crack in the ground that stretches from the east coast of the US to the Grand Canyon. This one has a ''lot'' of cracks following people down roads.
* In ''Film/PatchAdams'', the title character is ranting at God after [[spoiler:love interest Carin dies]]. At one point, he laments that of all the creatures on Earth, humans are the only ones who kill their own kind. Really, Patch? Ever watch the Creator/DiscoveryChannel? It'd be more accurate to say that humans are the only ones who feel bad about it.
* ''Film/ThePhantomPlanet'' features a plot point where atmospheric changes cause the protagonist to first shrink in size, then grow back to normal. There's also a throwaway line in the movie stating that the planet's inhabitants have been shrinking for centuries due to the planet's gravity.
* In ''Film/Plan9FromOuterSpace'', [[HumanAliens Eros]] informs the heroes that "a ray of sunlight is made up of many atoms." For the {{art major|Physics}}s out there: light is made of photons.
* Speaking of MST fare, if you know anything at ''all'' about [[{{Mayincatec}} Aztecs]] or UsefulNotes/AztecMythology, you're doing better than the creators of ''Film/PumaMan''. To take but one example, Stonehenge is apparently an Aztec artifact according to this movie.
* ''Film/{{Reptilicus}}'' gives us this little gem: "It's impossible. The skin tissue of the lizard. The cells seem to multiply like bacteria." As opposed to what? Did you expect the skin cells to multiply by laying eggs?
* ''Film/ThisIslandEarth'' has this line: "It's only Neutron. We call him that because he's so positive."
* In ''Film/{{Unknown}}'' nurse Erfurt brings a pair of metal scissors into the room with the MRI machine - which enables the protagonist to cut himself free and flee. Maybe the writers should have read up on [[http://jerlab.psych.sc.edu/kidsMRIsite/mrisafety/ mri safety]] - or the scissors were made of a metallic substance that was MRI-compatible, like aluminum.
* The kids' movie ''[[Literature/FiveChildrenAndIt 5 Children & It]]'' features a scene in which an eccentric math teacher is about to discover that kid-related shenanigans have been going on, while one of the kids is desperately trying to distract him by finding the answer to a complicated sum. The kid eventually announces that the answer is "3,486,522." The teacher beams "Ah! A prime number of the Siemens series!" and is successfully distracted. Admittedly, the average person might not know that there's no such thing as the "Siemens series" in mathematics, but anyone who ''entered'' high school would notice that 3,486,522 is even, and ''2'' is the only even prime.
* Creator/RolandEmmerich's disaster movie ''Film/TwoThousandTwelve'':
** [[http://www.youtube.com/watch?v=Hz86TsGx3fc This trailer]] for the film refers to the Mayans as "mankind's earliest civilization" within the first ten seconds. The Chinese, Sumerians, Babylonians, Greeks, and Egyptians are some of the many who say otherwise—also the Olmecs, who came up with the Long Count calendar all the brouhaha comes from in the first place.
** The film also attributes the apocalypse to mutating neutrinos. Neutrinos cannot mutate. Dara O'Briain was able to spin this into a very successful comedy routine, also noting that for all the explanation's value they might as well have said 'The Latinos have mutated'.
* In ''Film/{{Eraser}}'', Dr. Cullen (played by Vanessa Williams), apparently a physicist, explains that a rail gun fires "caseless aluminum shells ''at nearly the speed of light''."
* In ''Film/EnemyAtTheGates'', Commissar Danilov (Joseph Fiennes) is trying to win the affection of Tania (Rachel Weisz) by offering her leftovers from a party for apparatchiki, including a sturgeon, which was a very rare luxury in the Soviet Union, especially in the middle of the battle of Stalingrad. When she is reluctant to accept, he points out that there is nothing in their religion (they are both Jewish) that forbids them from eating sturgeon. Except for the fact that [[http://www.kashrut.com/articles/fish/ Judaism forbids eating sturgeon]].
[[/folder]]

[[folder:Literature]]
* ''Literature/AngelsAndDemons'', while famed for [[DanBrowned a sister trope]], has an example. The book claims that the Catholic Church copied communion (eating God) from the Aztecs. Even young children know that Europeans and natives of the more southerly regions of the Americas didn't meet until UsefulNotes/ChristopherColumbus' famous voyage of 1492... and that Christianity predates that voyage by about one thousand four hundred and sixty years. Also, the liturgies used by Orthodox Christians include communion, and some of them were composed by St. John Chrysostom, who ''died'' in 407 AD—four centuries before the beginnings of the Toltecs, the earliest civilization with any direct ties to the people we call Aztecs.
* In ''Literature/TheBFG'', the eponymous Big Friendly Giant [[WriterOnBoard goes on a rant]] about how HumansAreBastards because they're the only [[ApeShallNeverKillApe species that kill members of the same species]]. In reality, intraspecies killing (and cannibalism) has been common in many animals other than humans. [[spoiler:He gets proven wrong when the other giants try to kill him.]]
* * Robert E. Howard's Literature/BranMakMorn series contains an absolute howler, when the main character leads the barbarian tribes of England to a crushing victory against the Romans through use of the alien tactic of the shield-wall:
-->This was the first time the Roman legions had met with that unbreakable formation - that oldest of all Aryan battle-lines - the ancestor of the Spartan regiment - the Theban phalanx - the Macedonian formation - the English square.
:: A cursory look in a history-book at a Roman legionnaire, with his big, rectangular shield ''explicitly designed for shield-wall tactics'', will tell you exactly what is wrong with this picture.
* Creator/DanBrown's ''Literature/DigitalFortress'':
** The novel portrays the entire NSA, the world's preeminent codebreaking organization, scrambling around trying to figure out the answer to a simple riddle that anyone who took high school chemistry could easily figure out. On top of that, the answer to said riddle printed in the book is ''wrong''.
** The novel depicts Spain (and, specifically, Seville) as something resembling a Third World hellhole with, among other things, Spaniards unable to have normal wounds treated in hospitals.
* Jacqueline Rayner's ''Series/DoctorWho'' novel, ''The Last Dodo'', features "Mervin, the missing link between fish and mammals", which is just what it sounds like it should be. The thing is, we already ''know'' the steps between fish and mammals -- they're best known as ''amphibians and reptiles''.
** The back cover for ''Doctor Who and the Silurians'' describes ''TyrannosaurusRex'' as a 40-foot-tall ''mammal''. [[note]]And, of course, the character is [[IAmNotShazam not named Doctor Who]], but this error came from the title of the original serial.[[/note]]
* ''Literature/EndersGame'':
** In ''Ender's Game'', Col. Graff says that they're looking for the generation-changing human like those who invented "the wheel. And light. And flight." Except nobody invented ''light''. If he had said "the lightbulb" or "lights", then his statement would hold. Guess Graff just wanted to rhyme.
** In ''Ender's Shadow'', Graff claims one different gene is all it takes to make the genetically-modified [[spoiler:Julian "Bean" Delphiki]] a different species, since humans and chimps differ by 4% of DNA and it must have been a smaller percentage with Neanderthals. Except that 4% still contains ''35 million'' differences. People with Down Syndrome have an entire extra chromosome with 250 surplus genes and yet they aren't a different species. One could chalk it up as Graff simply being bad at science, except that the doctors responsible for the condition agree with the statement, even after it's confirmed that their subject ''doesn't'' have any genes different from humans; he has just an inert one turned on and an active one turned off.
* In ''[[Literature/TheHeroesOfOlympus The Son of Neptune]]'', Octavian claims that 'sea travel has never been the Roman way'. This could just be written off as Octavian being a dickhead and wanting to screw up the quest, but the sum total of the Roman navy turns out to be exactly one very shoddy boat. While sea travel wasn't wholly embraced, saying that it was never 'the Roman way' is a ''massive'' error, and it begs the question of exactly how the Romans conquered places like Britain without ships.
* In ''Literature/MobyDick'', Creator/HermanMelville[=/=]Ishmael consistently asserts that whales are fish. There's a whole chapter on it. He even goes on to warn of those who might lead the reader astray through talk of mammals and the like, which he essentially counters with "Come on guys, they're totally fish." Although he does acknowledge that they breathe air and give birth to live young, he still insists that they are, somehow, fish. Possibly a deliberate example of UnreliableNarrator, with Ishmael making the error, not Melville. Blurs with ScienceMarchesOn.
* In ''Literature/NightOfTheWolf'' by Alice Borchardt (sister of Creator/AnneRice), the claim is made that ''wolves do not mate for life''. This has been proven repeatedly to be false - they do.
* Creator/LarryNiven is famous as an author of "hard" science fiction, but even he isn't immune to the occasional whopper. In ''Literature/RingWorld'', he gets the rotation of the Earth wrong in the first chapter, by having the hero teleport eastward around the Earth in order to extend his birthday. Eastward, as in ''toward sunrise''. This is fixed in later editions.
* In Creator/ChristopherPike's book ''The Secret of Ka'', basic errors abound in the first thirty pages alone:
** There is no desert outside of Istanbul. Indeed, the city is right on the water, lying on the rather famous Bosporus Strait, in fact.
** Istanbul is likewise portrayed as an extremely violent city, similar to popular portrayals of places like the Gaza Strip, which it isn't. It's also portrayed as the capital of Turkey, which it also isn't.
** The narrator is scolded for saying "Hell" and "Christ," because she's in an Arab country. Turkey is a Muslim country, but not Arab.
* In the '70s horror novel ''Literature/TheSentinel'', author Jeffrey Konvitz talks about translating ''Literature/ParadiseLost'' from the "original Latin".
* In the Literature/SisterhoodSeries by Creator/FernMichaels, ''Free Fall'' depicts ''Japan'' as a Third World country that sells kids to Americans for 100 American dollars. Again, that's ''Japan'', as in the country that was widely believed to be [[JapanTakesOverTheWorld taking over the world]] only a decade or two before the novel was written.
* ''Literature/TheSongOfRoland'' is both a classic piece of literature and proof that this trope is OlderThanPrint. It claims within the first few pages that Muslims worship "Apollin" (who is either [[ClassicalMythology Apollo]] or [[BigRedDevil Apollyon]] (or both)), "Mahomet" (Muhammad, a statement equivalent to claiming that Christians worship the saints or the Jews Abraham or Moses) and, perhaps most bafflingly of all, "Termagant" (a figure who seems to appear only as one of the "Moslem gods"). Early medieval troubadours didn't have access to Wikipedia, or even Wiki/TVTropes. All they had was garbled traveler's tales, accounts written by classical travelers, and the knowledge of what makes a good story. They worked with what they had, which wasn't extensive. It is also claimed that Charlemagne is 200 years old, and the ''The Song of Roland'' got major details about the story's historical battle wrong (such as who the two armies were).
* Literature/TheSookieStackhouseMysteries briefly mentions Hepatitis D as a disease that affects only vampires. Not only is it a [[http://en.wikipedia.org/wiki/Hepatitis_D real illness]], it'd been known about for 24 years before the first book came out. [[Series/TrueBlood The TV show]] dealt with this by changing the disease to Hepatitis V.
* There's a ''Franchise/StarTrek'' book in which the author tried to convert from Fahrenheit to Celsius merely by subtracting 32, without dividing by 1.8 afterwards. As a result, a supposedly perfect paradise planet is said to have a mean surface temperature of a "pleasant 50 degrees centigrade". That's actually 122 degrees Fahrenheit.
** Another Trek book, the otherwise excellent ''The Romulan Way'', discusses the constructed language that the Romulans came up with when they left Vulcan by going back to an older version of the Vulcan language and "aging" it in another direction. The result is said to be as different from modern Vulcan "as Basque is from Spanish and their parent, Latin." Spanish is an Indo-European language descended from Latin...but Basque, famously, is one of the few languages of Europe that's ''not related'' to the I-E family in any way.
* In ''Literature/ToLightACandle'', a magically-made snow rose bush is grown, and the book mentions it has broad, flat leaves to catch as much light as possible. By the time you get into high school, it's pretty well known that coniferous trees, trees found in cold climates, have narrow leaves to conserve as much water as possible; a tree with broad leaves in a cold climate would die in months.
* Examples from the ''Literature/{{Twilight}}'' series, whose author, Creator/StephenieMeyer, has infamously bragged about doing as little research as possible. Garbled half-remembrances from high school abound:
** There's no way in ''HELL'' that a teacher would be allowed to administer a blood test without sending home permission slips informing parents ahead of time. Had Bella enrolled in school after the permission forms had been sent out and returned, chances are she would have been excluded from the experiment. And even failing that, no teacher who didn't want his pants sued off would ''grab a kid's finger and jab it with a needle''.
** Rosalie says that, as her father was a banker, her family wasn't hit at all by the Great Depression and still retained their wealth. Except anyone who stayed awake during history knows that bankers were among the hardest hit by the Depression, because most of the banks failed.
** The fourth book refers to giving Alice "free reign" over the wedding preparations. The correct term is free ''rein'', derived from the technique of loosening a horse's reins so it can go where it likes - i.e. you give someone free rein, you give them the freedom to do whatever they want.
* In Richard Lewis's 1980 eco-horror novel ''The Spiders'', the author is constantly referring to the title creatures as "insects."
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/AllyMcBeal'', another Creator/DavidEKelley show, makes many legal errors, but the law firm is shown to be "functionally corrupt" and ethically questionable in many ways. Why every single other person in the entire bloody legal system plays by the same rules, on the other hand, is an open question.
* The British "historical" drama miniseries ''Series/{{Bonekickers}}'' was so rife with simple factual errors, WebVideo/DiamandaHagan deliberately avoided doing research herself when reviewing it, reasoning that she could get more than enough material to criticize just from what she passively knew was wrong. She was correct.
* ''Series/BostonLegal'' frequently makes errors obvious to even non-lawyers. Lawyers routinely meet with judges without the presence of opposing counsel, evidence that has nothing to do with the case is introduced at the last minute, and the same firm occasionally represents ''both'' sides in a case.
* In the 2012 episode of ''[[Series/BradMeltzersDecoded Brad Meltzer's Decoded]]'', Brad brings up the prophecy of the "Blue Star Kachina" and mentions how NASA has recently discovered an actual blue star. They go on as if it's possible for an actual honest-to-goodness ''star'' to hit the Earth come December 21st 2012 - ''and ask a NASA guy about it.''
* ''Series/BuffyTheVampireSlayer'': In "Bewitched, Bothered & Bewildered" Amy casts a love spell by invoking Diana whom she describes as "goddess of love and the hunt". While Diana was indeed the Roman goddess of the hunt, anyone could tell you that Venus was the goddess of love. What's more is that Diana was one of three goddesses who swore never to marry. The closest she comes to being associated with love is becoming a goddess of childbirth in other myths. Of course, this could be why the spell goes so badly wrong.
* In ''Series/{{CSI}}'', Grissom goes to great lengths to say that the team are investigators, not policemen. Their job is to collect evidence at the scene and analyze it. But that doesn't stop [=CSIs=] from interrogating suspects, a practice that would normally be conducted by detectives, not crime scene investigators.
* In the "killer gamers" episode of ''Series/CSIMiami'', the bad guys are basing their crimes on the plot of [[UltraSuperDeathGoreFestChainsawer3000 a video game]]. [[PacManFever The only way the team can find out what happens next is to play the game.]] Anyone who has ever set foot in a video game store has seen shelves full of [[StrategyGuide Official Strategy Guides]] proclaiming "All Secrets Revealed!" on their covers. And Website/GameFAQs and other online sites, which will reveal those secrets for free! Failing that, you could probably find a [[LetsPlay playthrough]] on Website/YouTube.
* An episode of ''Series/{{CSINY}}'' had a corrupt ex-coroner who'd been stealing organs and tissues for a reason other than organ theft -to process them for the drugs they contained; the victims were all dead drug addicts from cases that came through his morgue. There wouldn't be enough of the drug left to get out, and it would be difficult to do so.
* ''{{Series/Dexter}}'' would sometimes look up potential victims of his prey, as well as their victims, on his ''police computer at the police station.'' Even if the computer's search history itself wasn't monitored, the police databases he would pull this info from had to be protected enough to keep tabs on who keeps asking for information...
* DoctorWho can get away with a fair bit; but sometimes the only reaction to something has to be "no it isn't". In "The Impossible Planet", the Doctor and Rose find themselves on the eponymous planet, which apparently is so-called because it's in orbit about a black hole. Which is ''perfectly'' possible; a planet can orbit a black hole as easily as it can orbit any other massive body. What would be much more difficult would be to remain ''hovering'' over the hole, while material in the hole's accretion disk (which is in orbit) continually blows over it. That's actually the situation in the story, but somewhere along the way the exposition fell over and sprained an ankle.
* ''Series/{{Elementary}}'': Holmes, during a SherlockScan, states that the weapon with which a detective was attacked had the "high-end modification" of ''rifling''. That's been a standard for the past 200 years for any gun that isn't a shotgun.
* On January 18, 2012, the commercials for ''Series/EntertainmentTonight'' previewed a story about the Concordia cruise ship capsizing disaster, which they called "The RealLife Film/{{Titanic}}". [[AluminumChristmasTrees One would think the real-life Titanic]] would be, well, ''[[UsefulNotes/RMSTitanic the Titanic]]''.
* ''Series/{{Heroes}}'':
** Almost any time someone mentions evolution, you can bet it will be entirely wrong. The book of a biology professor claims that the right combination of genes could do things that blatantly break the laws of ''physics''. The son of said professor seems to believe natural selection works by ''destiny'', randomly selecting an individual to be awesome, instead of gradually weeding out unfavorable mutations and allowing better mutations a better chance to survive.
** The son also states that individuals with beneficial mutations have to fight harder than other people to survive. Which not only fails biology, but also inverts the definition of "beneficial".
** And those ever-so-convenient eclipses, which somehow occur all over the planet. Even in Japan and the United States simultaneously, never mind how it'd be ''the middle of the night'' in one when it's mid-day in the other. Season 3 even has a two-parter where an eclipse lasts for several hours (which is... unlikely, to say the least).
* In one episode of ''Series/HowIMetYourMother'' Barney states that the wait three days to call a girl rule was started by Jesus since he waited three days to come back to life. Except Jesus waited two days not three. He was crucified on Good Friday and came back on Easter Sunday. The confusion likely comes from the fact that Easter is often referred to as the third day after his death, but this would mean that in order to wait three days he would have had to wait all the way through Sunday and then come back on Monday.
* In the 2000 TV series ''Series/TheInvisibleMan'', Darien's surface temperature drops below freezing when he turns invisible. The reason given is that no light is hitting him, but this isn't a plausible one as his body is still generating heat. Not to mention that people's skins generally don't start freezing if they turn the lights out.
* In ''{{Series/Jeremiah}}'' there is a flashback scene where Ezekiel's father gives him a long-winded speech in which he states that the Big Death was really just a case of life overcoming adversity and flourishing; therefore even though it killed off a significant portion of the human race, it's actually sort of beautiful. This ignores the fact that it had been established that the Big Death was caused by a virus, which are not alive. This isn't just an academic point, since a perfectly virulent virus would end up destroying both the host species and itself; without any more cells to incubate it, the virus itself would become extinct.
* ''Series/MightyMorphinPowerRangers'', in "Return of the Green Ranger," features the Rangers going back in time to the late 1700s, where Angel Grove is a colonial town filled with British soldiers. Angel Grove is in California, which was originally ruled by Spain, and wasn't inhabited by Americans until the mid-1800s. [[MST3KMantra Then again, this is the same show that has giant animal robots form into a giant humanoid robot with a sword piloted by teenagers who fight an evil sorceress and a skinless emperor, so maybe we shouldn't try to apply logic to Power Rangers..]]
* The Taiwanese adaptation of ''[[Series/MillionDollarMoneyDrop The Million Pound Drop]]'' does this often enough to lead to suspicions that the show is rigged. Frequently, a blatantly false "correct" answer is given for an answer that happens to be one that the contestants left empty. One particularly obvious incident was when they claimed the correct answer to "Which of these animals is warm-blooded?" was ''salmon''.
* ''Series/{{NCIS}}'' plays it pretty loose with science and technology, but a few examples are glaring enough to qualify for this trope:
** During one episode, the NCIS computer network is being hacked by someone. Abby madly taps at her keyboard to try and counter this but isn't fast enough. So [=McGee=] jumps on the other side of the keyboard and they madly tap away at ''the same time, on the same keyboard!'' Unless anti-hacking software somehow involves a mini-game with a two player mode then they aren't going to accomplish anything.
** And again, on the premiere episode of the ninth season, [=McGee=] suggests a fun gaming lounge that the team can go to, saying it has "3D, {{P|layStation2}}S2 and a 60" plasma." The [=PS2=] rarely ran high-definition, let alone 3D.
** The team routinely drives up and down Virginia multiple times an episode, which ''may'' be possible for a state Virginia's size, but is a bit of a stretch.
* ''Series/TheOReillyFactor'', in an example that produced no less than two [[MemeticMutation memes]], had O'Reilly claiming that there was no scientific explanation for tides, notoriously claiming "You can't explain that!"[[note]]meme one[[/note]] while the guest he was interviewing, David Silverman, stared at him with a face that just ''screamed'' "you can't be serious"[[note]]meme two[[/note]]. For bonus points, when the mechanics behind tides were later explained to him, he showed his lack of understanding of the scientific method by claiming that tidal forces are "[[GravityIsOnlyATheory just a theory.]]"
* In ''Series/RedDwarf'', the usually very well-informed Kryten thinks that Virgil's ''Aeneid'' is about the rescue of Helen of Troy. Nope: that was Homer's ''Iliad''.
* Reviews On The Run's 2010 Blu-Ray award special gave the best voice actor to Creator/KevinConroy for his performance in ''WesternAnimation/BatmanUnderTheRedHood''. While Conroy voiced Batman in the Franchise/{{DCAU}} and for some other projects, he wasn't in ''Under The Red Hood''. That was Bruce Greenwood.
* In one episode of ''Series/StarTrekTheNextGeneration'', a character describes Picard as being "two meters tall". Given that he isn't even close to that height (equivalent to about 6 foot 7 inches), the writer clearly didn't know the metric system. Joked about in Picard's last appearance, ''Film/StarTrekNemesis'' -- Picard and his clone both lament not having reached two meters in height.
* In the ''{{Supernatural}}'' episode "It's the Great Pumpkin, Sam Winchester", everyone in the episode, from the Winchesters to the angels, pronounces the name Samhain as "Sam Hane", when it's actually pronounced "Sawin".
** In the episode "I Believe the Children Are Our Future", Castiel tells Sam and Dean that, despite what (he says) the Bible says, the Antichrist is not the son of Lucifer but just the spawn of a demon. In actuality, the Bible doesn't say that the Antichrist is the child of the devil at all, just that he's an evil human leader who rises up.
* ''Series/TheUniverse'' had an episode on Mercury and Venus, calling them the two most hostile terrestrial planets in the solar system. So far, so good. The problem was that when the narrator said "Mercury" in the opening, Venus was shown, and vice versa. The two planets look nothing alike: Mercury looks like our moon, while Venus's surface is completely hidden by its clouds.
* ''Series/TheWeakestLink'' research team has proved itself to be the weakest link on occasion:
** When the question "UsefulNotes/{{Montreal}} is the capital city of which Canadian province?" was asked to a contestant, the show claimed the answer was Quebec, while in fact the correct answer is ''none'': Quebec City is the capital of Quebec.
** The question "In which century did the First World War take place, the 19th or the 20th?" gave the right answer as "the 19th".
* ''Series/ZeroHour'', which centers around a conspiracy related to Jesus' apostles, seems to think that Luke was one of the twelve. Ten seconds on Google would have confirmed that he wasn't.
* The ''[=AwesomenessTV=]'' sketch "Terry the Tomboy" got the "tomboy" part completely wrong. Apparently the showrunners think "tomboy" means "redneck stereotype".
[[/folder]]

[[folder:Music]]
* Meg and Dia's song "Fighting for Nothing" has this line, "But I know that/I was put here/To fight Vikings in The Cold War". Given that it's eight or nine centuries off, it was probably intentional.
* Music/MichaelJackson's "Liberian Girl" not only opens with Swahili, but with a South African singer singing it. They speak Swahili in East Africa, Liberia is in West Africa.
* Music/NeilYoung has a song called "Cortez the Killer", in which he praises the pacifist and egalitarian... ''Aztecs!?'' Seriously, he comes right out and says "Hate was just a legend, / And war was never known" while he's talking about [[http://www.cracked.com/article_16972_5-most-terrifying-civilizations-in-history-world.html one of the bloodiest civilizations in human history]]. He also says they "lifted many stones" and "built up with their bare hands / What we still can't do today." So, which early 16th century Aztec stone buildings were unmatchable by 1970s technology exactly?
* There is a Dutch DJ who, as of October 2011, claims to get phone calls from Madonna and Frank Sinatra on a regular basis. His phone bill must be through the roof, because Sinatra died in May ''1998''. (Maybe he's talking about Frank Sinatra, Junior?)
* The liner notes for the 2003 edition of Music/{{Yes}}' ''Going For The One'' claimed that "Not one punk band topped the U.K. album charts during its Year Zero of 1977...". Either the writer is driving a BiasSteamroller or has probably never heard of a little punk band called Music/TheSexPistols, whose album, ''Never Mind The Bollocks, Here's The Sex Pistols'', topped the charts in the U.K. in November of 1977 and stayed there for two weeks.
* There was a period in the 2000s when the media ([[http://www.dailymail.co.uk/femail/article-566481/Why-child-safe-sinister-cult-emo.html The Daily Mail, at least]]) tried to convince people that "emo" was a "cult" and that the "[[Music/MyChemicalRomance Black Parade]]" was a Valhalla-type place where emos go after they die.
[[/folder]]

[[folder:Newspaper Comics]]
* An early ''ComicStrip/{{Garfield}}'' strip featured Garfield reciting a short poem about spiders. Problem is, he refers to them as insects, when they are actually arachnids. This was pointed out in the author's notes for [[http://www.mezzacotta.net/garfield/?comic=204 this]] Webcomic/SquareRootOfMinusGarfield.
[[/folder]]

[[folder:Radio]]
* An episode of ''[[Radio/FagsMagsAndBags Fags, Mags and Bags]]'' centering around the local rabbi, imam and priest all [[ItMakesSenseInContext sitting in the same bath of baked beans for charity]] includes the priest's disappointment that as the representative of the newest Abrahamic religion, he has to take the traditional youngest sibling place at the tap end. This line should really have gone to the imam.
[[/folder]]

[[folder:Tabletop Games]]
* The entire firearms section of ''TabletopGame/CallOfCthulhu'' is full of errors obvious to anyone with a cursory knowledge of the history of firearms. For example, silencers are depicted as having been invented about a century before they actually were.
* The first ''TabletopGame/{{Rifts}}'' sourcebook, printed in the 1990s, had an animal/monster race called the Ostrosaurus. In the description, they note that despite the name, it's not a lizard like a dinosaur, but closer to a featherless bird. The irony kicks in with the realization that [[ScienceMarchesOn Theropods, which the Ostrosaurus resembles, essentially were featherless birds]]. Or more accurately, [[SomewhereAPaleontologistIsCrying birds are feathered dinosaurs]].
* The TabletopGame/TopTrumps card game has FlavorText that attempts to be informative and educational, but the creators don't seem to have done very much research. There's a particularly monstrous error on the "Life" card in the "Wonders of the World" pack:
-->The first known animals to roam the Earth were dinosaurs, over 65 million years ago.
[[/folder]]

[[folder:Theatre]]
* Creator/WilliamShakespeare, as the son of a glove-maker whose schooling mostly included Latin and classic literature (written in Latin), was prone to making these when discussing geography. His plays also include a healthy dose of AnachronismStew - allusions to Christian themes are frequent even in stories that took place before Christ was born, there are references to contemporary English clothing and culture regardless of setting, etc., so how much of those errors are just stylistic choices is debatable.
** In ''Theatre/TheWintersTale'', Shakespeare committed a Critical Research Failure and was called out on it by his contemporary, Ben Jonson. Shakespeare had his characters shipwrecked on the coast of Bohemia (which is now the Czech Republic) "where there is no sea near by one hundred miles." Shakespeare's mistake was likely [[TheArtifact an artifact]] from his original source, which took place in Sicily, not Bohemia.
** In ''Theatre/AntonyAndCleopatra'', Cleopatra suggests playing a game of billiards, a game which wouldn't exist until about 1000 years later.
** ''Theatre/TwoGentlemenOfVerona'' has a plot point often regarded as a Critical Research Failure, but it's actually an aversion. While the gentlemen and their servants take a ship to get from Verona to Padua (or Milan, the script says both at different times), and all three cities do not have access to the sea, the three cities ''did'' have access to an extensive network of canals linking Verona to Padua and Milan, as well as to various points within each city. Some of these canals [[http://www.gwu.edu/~ieresgwu/assets/docs/CanalsofMilan.pdf are still around today]], though their transportation uses have been replaced by modern transportation methods.
** ''Theatre/TheTempest'' has a similar aversion in Act I Scene 2, where we are told that Prospero and Miranda were taken from Milan by "bark" (i.e., "barque," a type of ship) "some leagues to the sea," where they were put aboard "a rotten carcass of a boat". Again, while Milan lacks direct access to the ocean, it did have access to an extensive network of canals, and the Grand Canal (''Naviglio Grande'') [[http://www.gwu.edu/~ieresgwu/assets/docs/CanalsofMilan.pdf is still around today]].
** In ''Theatre/JuliusCaesar'', Caesar proclaims himself to be "constant as the Northern Star". As was well-known to educated people by Shakespeare's time, the Northern Star isn't a constant (which it currently is is affected by the precession of the equinoxes) and there are even long periods when there isn't a Northern Star -- such as Caesar's time. Creator/IsaacAsimov called out Shakespeare on this in his essay "Constant as the Northern Star" -- partly as evidence that the plays (or at least ''Julius Caesar'') couldn't (as some people suppose) have been written by Francis Bacon, as Bacon was well-educated and would have known this.
*** Brutus is spooked by the ghost of Caesar in the middle of reading a book centuries before bookbinding was created.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/BatmanArkhamCity'' features the Penguin bragging about how the machine guns he makes available to mooks can fire over 100 rounds per minute. While this is technically true, the line probably should have been "per second" instead.
* In the PSP game ''{{Def Jam| Series}}: Fight for NY: Takeover'', there is plenty of cringe-inducing trash-talk that gets tossed back and forth before almost every fight in the main storyline. One of the opponents you can fight for money in the Dragon House is Prodigy. All trash talk pertaining to this opponent makes reference to him claiming to be a prophet. Prodigy, prophecy, what's the difference?
* The StrategyGuide for ''VideoGame/PokemonRedAndBlue'' that was published by Versus Books is considered SnarkBait by people even moderately good at the games, because of [[EightPointEight how badly underrated many of the Pokémon were]], but the MostTriumphantExample of research failure is the claim that several Pokémon which do not learn any moves of their type through leveling up would have just been better off being Normal-type, so that they are unaffected by ElementalRockPaperScissors (which isn't true either; Normal is weak to Fighting but mutually immune to Ghost). Because apparently [=TMs=] don't exist or something.
* In ''VideoGame/RiseOfNations'', the "Kremlin" wonder looks nothing at all like the Kremlin. It does look very much like a large cathedral (St. Basil's) that is next to the Kremlin.
* In ''Koudelka'', the first part of the ''VideoGame/ShadowHearts'' series, the action takes place in an old abbey in Wales, which the manual says is a "small country in the north of England." Wales is southwest of England, but calling it a country is a stretch - it's part of the UK. It's a fairly common error in Japan (and other parts of the world as well) [[BritainVersusTheUK to think England, Britain, and the United Kingdom are synonymous]].
* PETA's video game parodies tend to fall into this. ''VideoGame/SuperTanookiSkin2D''[='=]s entire "fur is murder" message is undermined by the fact that ''the titular [[VideoGame/SuperMario3DLand Tanooki Suits]] aren't made from actual tanuki''. Then there's ''Franchise/{{Pokemon}} Black and Blue'', which completely omits the whole "trainer-Pokemon trust" part of the franchise.
* Sony's embarrassing slip-up at E3 2006: "The stages of the game will also be based on famous battles that actually took place in Ancient Japan. ''[Demonstrating the game]'' So here's this GiantEnemyCrab..."

[[/folder]]

[[folder:Web Original]]
* ''WebVideo/TheAngryVideoGameNerd'' ranted, among other things, about being killed by a frog in ''Super Pitfall''. [[http://en.wikipedia.org/wiki/Granular_poison_frog The Granular Poison Frog]] has killed more than a few people, and yes, it lives in the jungle. That's also not counting people killed by weapons dipped in their poison, or various other kinds of frogs from the jungle that are also deadly to the touch.
--> '''AVGN:''' Has anyone ever died by being attacked by a fucking frog?![[note]]Yes.[[/note]]
* ''Website/GaiaOnline'' made a terrible mistake whilst describing a new item called Lala the Koala Plushie.
-->"Lala the Koala Plushie pays tribute to the noble koala bear, which is now just returning from hibernation to resume it's [sic] voracious consumption of eucalyptus".
** While regular bears hibernate, koalas (which are not bears, or even placentals) live in Australia, which even in its temperate zones doesn't get cold enough to necessitate hibernation.
* In the ''[[Creator/RedLetterMedia Half in the Bag]]'' [[http://www.youtube.com/watch?v=-x1YuvUQFJ0 preview]] for their ''{{Film/Prometheus}}'' review, Mike claim that there were 65 million years of dinosaurs before humans. Unfortunately, he has that backwards: dinosaurs have been ''extinct'' for 65 million years.
* The [[MemeticMutation now-memetic]] "Jimmy [=McPerson=]" essay includes, among others:
** Having Jimmy grow up in Illinois while living in Harlem.
** Having the Japanese attack Jimmy's town, when neither NY nor Chicago was attacked.
** Alleging blacks couldn't join the military in UsefulNotes/WorldWarII because Martin Luther King Jr. wasn't born yet. Yes, they could, and MLK was born in 1929.
** Jimmy meets with the president of Japan. [[FridgeLogic President of the Japanese Empire?]]
** There's also the rather hilarious image of Jimmy fighting off "[[AnachronismStew countless samurai and ninjas]]" in his quest for revenge.
** Jimmy battles with both said president/emperor/whatever AND Hitler.
** Jimmy kills Hitler in a suicidal charge. [[DrivenToSuicide Which is not how Hitler died.]]
* ''Creator/TheMysteriousMrEnter'' claimed in his [[http://www.youtube.com/watch?v=q0XawmU9zn4 Animated Atrocities review]] of the ''WesternAnimation/SpongebobSquarepants'' episode "One Coarse Meal" that whales only eat krill, ignoring that some whales in RealLife actually ''do'' [[http://www.whalefacts.org/what-do-whales-eat/ eat plankton]].
** He actually does bring up this point in his "Top 11 Worst Episodes Reviewed" video, admitting he did some research and yes, some whales do eat plankton...and then points out that some whales also eat crabs, fish, and squid.
** In the same video, he mentioned that Pearl was a Sperm Whale, which doesn't eat plankton.
* ''WebVideo/TheNostalgiaCritic''
** In a satirical skit (so the character's stupidity isn't an excuse), he once called ''Literature/TheLittleMermaid'' "English". What's weird is that back in Disneycember, Doug knew all about the book and compared it to the Disney movie.
** In his review of ''Film/PearlHarbor'', he embarked on a [[TheReasonYouSuckSpeech Reason You Suck Speech]] about how Michael Bay had disrespected the sailors who were at Pearl Harbor by, among other things, having a sailor shout, "I can't swim!" before falling into the water. Not only was it common for sailors to not know how at the time (swim tests in the Navy weren't introduced until years later), but Doug's father is a Navy veteran, so he had easy access to the correct information.
* In Quality Control's review of ''Anime/{{Interstella 5555}}'', he claims that ''Discovery'' was Music/DaftPunk's first album. ''Discovery'' is their second album. ''Homework'' was their first.
* Website/SFDebris has a couple minor examples. Chuck says in his ''Batman Beyond'' review that the movie was censored because it was judged too violent. While that helped, the real catalyst was the Columbine Shooting that occurred before the film came out. Another small error is in his review of ''Series/TheXFiles'' episode "Aubrey", where Chuck says Harry Cokley (a suspect in unsolved serial murders from the 1940s) did only 8 years for attempted murder and rape. In the dialogue, however, it's said he was convicted in 1945 and released December 5th, 1993, meaning he must have served 4''8'' years at least.
* In spite of ''DeathBattle'' being known for [[ShownTheirWork showing their work, even they have their moments.]]
** "Kunoichi" is a term for female ninja, not DistractedByTheSexy as Wizard claimed, but this is understandable since the latter was a major tactic employed by the former.
** In the TeenageMutantNinjaTurtles Battle Royale, Michelangelo is often stated to have the most potential as his overcomplicated weapons prove he's Brilliant, but Lazy instead of Too Dumb to Live, and he's also Battle Nexus champion, but neither of these facts are brought up in analysis. Interestingly, the ''character'' Wizard hates Michelangelo but the annotations of the first Q and A video reveal that Ben and Chad actually ''prefer'' Mikey over the other turtles.
** The hosts claim that Shao Kahn is immortal because of all the souls he keeps stealing. While he can and does steal souls [[spoiler:and likely would have defeated M. Bison regardless]], nothing in the canon suggests that this is the source of his immortality.
* In the short EC Gunge story, [[http://www.ecgunge.net/stories/ "Curry" On Louise]], the Islamic men tell off Louise for adding 'Halal' meat in their curry, and punish her by [[CoveredInGunge covering her in curry.]] The problem is that 'Halal' means 'permissible', as in, they are allowed to eat the curry. The correct term would be 'Haraam'. Instead, it comes off as the Muslims at the restaurant behaving like [[JerkAss Jerkasses,]] for serving them legal food.
* Creator/BobChipman once did an episode about how ''Franchise/{{Halo}}'' was racist because the UNSC was composed of white people, while the Covenant were ethnically diverse. However, both of these are quite false. Sergeant Johnson, one of the biggest badasses in the series and a fan favorite, is black, the Elites leave the Covenant to assist humanity in ''Halo 2'', and in ''Halo: Reach'', the majority of the place names are Hungarian, while Emile is black and Jun is Chinese, making it clear that the UNSC is composed of ''all'' of humanity. As for the Covenant, while they do have a wide range of alien races, they're segregated in a strict caste system and most of them are enslaved; hardly a shining example of ethnic diversity.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'':
** Jimmy does a report on Thomas Edison. Why? Because Edison ''invented electricity''.
** Another particularly glaring example was that Jimmy in one episode refers to the Cretaceous period as the Cretaceous ''era'' (the era was the Mesozoic), and that it ended 200 million years ago. Any dinosaur-crazed eight-year-old could tell you that it ended 65 million years ago.
** The series has a surprising tendency to do this. Other examples include claiming that Chinese ginseng is a muscle relaxant, Australia isn't a continent, and that ''people can never change because their personality is imprinted on their brain at birth''.[[note]]The latter two examples are argued against in-series, however.[[/note]]
* In Yakko Warner's otherwise wonderful song from ''WesternAnimation/{{Animaniacs}}'' where he lists [[http://www.youtube.com/watch?v=x88Z5txBc7w all the nations of the world]], Ireland isn't noted as being ''two'' countries (Northern Ireland and the Republic of Ireland, although the animators actually include the divide!) and Wales is the only country in the United Kingdom not mentioned at all.
** Also, the Korean peninsula is made up of two separate countries: The Republic of Korea and the Democratic People's Republic of Korea.
* An episode of ''WesternAnimation/ArchiesWeirdMysteries'' had a mummy haunting the museum it was kept in. It turns out the mummy was vengeful because his fiancée left him because he kept putting off their wedding until after his pyramid was built. One, pyramids tended to take a pharaoh's whole life to build and sometimes weren't completed until after their death; two, pharaohs were married as children; and three, a pharaoh's marriage was arranged for them between them and one of their siblings, so no one could just decide to leave a marriage they were fed up with.
* ''WesternAnimation/{{Ben 10}}'' claimed in one episode that the mysterious "[[{{Unobtainium}} Bicenthium alloy]]" was extremely rare on any planet except Earth... except the "alloy" was ''iron'', the sixth most common element in the galaxy. And iron ''isn't an alloy''.
* ''WesternAnimation/DanVS'' gives us "Sergeant Saskatchewan", an overly patriotic Canadian CaptainErsatz of Comicbook/CaptainAmerica... who wears the ''American sergeant emblem on his sleeve.'' Then seconds later Dan encounters a man asking for donations to save the Canadian geese. You'd think this guy would know it's "''Canada''" geese, not "Canadian" geese.
* ''WesternAnimation/TheFairlyOddParents'':
** One episode treats the giant squid as a mythological creature. [[EskimosArentReal It's a real species.]]
** "Fairy Idol" shows penguins living at the North Pole. Not just a few, but a whole rookery (though a lot of American cartoons show [[PolarBearsAndPenguins penguins as North Pole animals rather than South Pole/Antarctic animals]], so it's not that much of a surprise).
* A terrible offender is ''WesternAnimation/TheMummyTheAnimatedSeries'' in the episode "The Cloud People". Lake Titicaca is described as both puma-head shaped and as being found below the ruins of Macchu Picchu. A ''portion'' of the lake's southern bank [[http://en.wikipedia.org/wiki/File:Lake_titicaca.jpg vaguely resembles a cat's had in profile]], but only if viewed from the air while flying north-to-south. The whole thing, not so much, and it's still southeast of Machu Picchu, not below it.
* Two of the ''Franchise/ScoobyDoo'' movies hit this particularly hard, mainly because the two movies between them got their respective monsters BACKWARDS. {{Chupacabra}} is a reptilian [[OurVampiresAreDifferent hematophage]] that preys on goats. The Australian {{Yowie|sAndBunyipsAndDropBearsOhMy}} is supposedly a large humanoid creature, along the lines of [[BigfootSasquatchAndYeti Bigfoot and the Yeti]]. ''Monster of Mexico'' says that Chupie is Bigfoot, and ''Legend of the Vampire'' that the Yowie is a vampire. It's easy to think that they picked monsters that [[ViewersAreMorons they thought nobody knew]], but Chupacabra at least is rather well-known.
* In the ''WesternAnimation/XMen'' episode "Days of Future Past, Part 2", Gambit travels to UsefulNotes/WashingtonDC. But the monitor shows the ''state'' of Washington (with Washington, D.C. captioned right below).
* When ''WesternAnimation/FamilyGuy'' makes one of its many, many {{Take That}}s at religion, you can bet that the writer will get every one of their facts wrong. For example, when Stewie mentions about how there was no war before Jesus' birth, a cutaway shows friendly men fighting each other immediately because Jesus was born, even though there were wars ''before'' Jesus was born.

!!In-Universe examples

[[folder:Comic Books]]
* The ordinarily GenreSavvy ComicBook/AmbushBug once made a huge error InUniverse. Seeing a young blonde woman in a familiar costume flying by, Ambush Bug immediately realized that some malevolent magic or Red Kryptonite [[GenderBender had turned his "pal" Superman into a girl]], and that Superman desperately needed the Bug's help. Somehow, Ambush Bug was completely ignorant of the existence of Comicbook/{{Supergirl}}, who was naturally mystified by the encounter. (Supergirl, InUniverse, was publicly known and quite famous in her own right at the time.)[[note]]Supergirl #16 (1984)[[/note]]
* In the ''SupplementalMaterial/TeamFortress2'' comic ''Ring of Fired #1''. When the Demoman and his sentient sword the Eyelander are watching the show ''Ghost D.A.'', the title ghost character disappears with a "doodily-doodily-doot" noise. The Eyelander, which is possessed by a ghost, points out that ''it'' never does that and questions whether the writers are actually ghosts. It has more to complain about when the TV ghost puns "the defense rests... in peace."
-->'''Eyelander''': Ugh. "The defense rests"? He's the @$%ing prosecution! Ghost D.A.! "District Attorney!" It's in the title of the @$%ing show!
** Turns out the entire town of Teufort suffers from a major case of this in ''Unhappy Returns''. The Mayor is apparently completely oblivious to what he can and can't do in his position, apparently thinking he's allowed to force someone to become a fake-italian, and hang people without a trial. No one else in the town finds a problem with this. [[spoiler: This is due to them having drunk toxin-contaminated water for over a generation.]]
[[/folder]]

[[folder:Fan Works]]
* In an in-universe example, the LemonyNarrator of [[Fanfic/EquestriaAHistoryRevealed Equestria: A History Revealed]] seems to fulfill this trope in spades. To her credit, she does do research, but she blatantly ignores what is stated in favor of her own opinions, going as far as to cross out sections of quotes that [[BiasSteamroller don't agree with her view]].
* ''FanFic/ABriefHistoryOfEquestria'': Apparently it's common -- due to their rivalry prior to and during the [[MeleeATrois Lake Trot Crisis]] -- to portray Viscount Arsenic as Lady Cripps' father, who abandoned her mother after a brief affair. This despite the fact that at the time of said affair, Arsenic was ''two years old.''
* The fictional authors' works in ''Fanfic/BleachFanWorks'' have several of varying severity. For example, Christina doesn't realize who Oshima[[note]]an extremely minor character who tries to threaten Ichigo, only to get taken down by Chad[[/note]], while Jolene Myer has Ichigo's father called "Barnubus" rather than Isshin, and claims that Masaki divorced him when the twins were born (instead of getting killed by Grand Fisher [[spoiler:and Yhwach, although they most likely couldn't have known that when this installment was uploaded]]).
* In ''WebAnimation/TurnaboutStorm'': [[Franchise/AceAttorney Phoenix]] makes a loud objection during the trial when it's revealed that the decisive evidence against the defendant is a storm cloud, mocking the prosecution for suggesting that his client could move that cloud around and make it shoot lightning at will. Too bad he happens to be in [[WesternAnimation/MyLittlePonyFriendshipIsMagic Equestria]], a world where [[PaintingTheFrostOnWindows controlling the weather]] is a common sense fact.
-->'''Phoenix''': Oh... Hehe... Sorry! My mistake...
-->'''Twilight''': Maybe you should have... Oh, I don't know, ''studied!?''
-->'''Phoenix''': I said I was sorry!
** Shortly after he makes another mistake in trying to contradict a statement, pointing out that the thunder is heard after the lightning strike, not at the same time. Not in Equestria, though.
[[/folder]]

[[folder:Live-Action Film]]
* Bluto's speech in ''Film/AnimalHouse'' gives us this gem:
-->"Over? Did you say "over"? Nothing is over until we decide it is! [[ArtisticLicenseHistory Was it over when the Germans bombed Pearl Harbor?]] Hell no!"\\
"Germans?"\\
"Forget it, he's rollin'."
* S.H.I.E.L.D of all people have this at the end of ''Film/CaptainAmericaTheFirstAvenger''. After Steve Rogers is [[HumanPopsicle unfrozen]] after crashing the HYDRA Valkyrie in 1945, they try to ease him into the present day by building a fake 1940's hospital room, complete with a 1940's baseball game broadcast "live" on the radio and a woman in period-appropriate attire entering to greet him. However, Steve immediately notices something is wrong - [[SpottingTheThread because the "live" baseball game is from 1941]], he knows ''because he was there''. Cue him breaking out and experiencing massive culture-shock at 21st Century Times Square. [[SarcasmMode Nice going, S.H.I.E.L.D.]]
* In ''Film/DrStrangelove'', the Russian ambassador explains that the Soviets built their world-ending machine because they feared a "Doomsday-gap" when they "discovered" that the Americans were building one. When the US President truthfully rebukes that as a ludicrous fantasy, the ambassador replies : "[[EpicFail our source was the ''The New York Times'']]"
* ''Film/TradingPlaces'' has this example from the heroes' MassiveMultiPlayerScam:
-->'''Coleman:''' Let me see, you would be from Austria. Am I right?\\
'''Ophelia:''' No, I am Inga from Sweden.\\

* The title character in ''Film/TheFortyYearOldVirgin'' displays his complete lack of sexual experience when he mentions that breasts feel like bags of sand.

* The villains of ''[[Literature/ASeriesOfUnfortunateEvents The Slippery Slope]]'' proudly boast about how they control "two of the greatest mammals: the lions and the eagles!" [[TheSmartGuy Klaus]] calls them out on their error, but they don't care.
* ''Literature/TheCatcherInTheRye'':
** Holden Caulfield writes a paper about ancient Egypt, which reads thus: "The Egyptians were an ancient race of Caucasians residing in one of the northern sections of Africa. The latter as we all know is the largest continent in the Eastern Hemisphere. The Egyptians are extremely interesting to us today for various reasons. Modern science would still like to know what the secret ingredients were that the Egyptians used when they wrapped up dead people so that their faces would not rot for innumerable centuries. This interesting riddle is still quite a challenge to modern science in the twentieth century." That is the paper, in its entirety.
** The title of the book comes from Holden mistaking a line from the song "Comin' Through the Rye". He thinks it's "If a body catch a body comin' through the rye", but it's really "If a body '''meet''' a body comin' through the rye."
* ''[[Literature/EndersGame Ender's Shadow]]'': Bean's nemesis Achilles thinks that UsefulNotes/JosefStalin was promoted by UsefulNotes/VladimirLenin then imprisoned and killed him, when in reality Lenin died of a stroke while urging his followers to not put Stalin in charge. His mistaken belief may be due to his own lack of schooling coupled with his desire to become a dictator twisting his memory of history.
* An in-universe example from ''Literature/FearAndLoathingInLasVegas'', when the police drug 'expert' tries to explain why a marijuana cigarette is colloquially referred to as a "roach".
-->''"What the fuck are these people talking about?" my attorney whispered. "You'd have to be crazy on acid to think a joint looked like a goddamn cockroach!"''
* From Creator/GordonKorman's ''Son of the Mob 2'': Vince is heading off to film school in California with his girlfriend and best friend and decides to chronicle their road trip in script form. His girlfriend immediately points out one minor problem: he has them driving ''west'' into the ''rising'' sun.
* ''Franchise/HarryPotter'': ''Literature/FantasticBeastsAndWhereToFindThem'' mentions a {{Kappa}}, and states it's Japanese. One of Harry's notes next to it says "Snape hasn't read this book either", since Snape identifies Kappa as Mongolian in ''Literature/HarryPotterAndThePrisonerOfAzkaban''.
* ''Literature/TheHitchhikersGuideToTheGalaxy'':
** Ford Prefect chooses his name - the name of a rather mediocre British car - apparently on the assumption that cars were the dominant species on the planet. The movie adaptation extrapolates from this the scene of Ford and Arthur's first meeting - Arthur saving Ford from attempting to shake hands with a car.
** The CutawayGag sequence about the [[LawOfAlienNames Vl'Hurg-G'Gugvuntt]] fleet that attempted to invade the Earth, only to be accidentally swallowed by a small dog in its entirety 'due to a terrible miscalculation of scale'.
* ''Literature/TheHungerGames'': Delivered by none other than [[FeigningIntelligence Effie Trinket]]: "Well, if you put enough pressure on coal it turns to pearls."

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'': Whenever [[AmbiguouslyGay Andrew]] flexes his [[TheStoryteller storyteller]] [[FlexingThoseNonBiceps muscles]]. He'll usually include events of which he has no first-hand knowledge (i.e. [[ContinuityNod previous seasons]]) in his spiel and is thus occasionally widely off the mark. For example, when he talks to the Potential Slayers about Faith he claims that she killed a [[Franchise/StarTrek Vulcan]], "the most pacifist and logical of races". Flashback to Faith locked in deadly hand-to-hand combat with a Vulcan (she killed a volcanologist). When one of the Potentials tries to correct him, he says "Why would she kill someone who studies Vulcans?"
* Creator/StephenColbert of ''Series/TheColbertReport'' uses this intentionally and mixes it with InsaneTrollLogic [[PlayedForLaughs for laughs]]. This is really the entire premise of the show.
* ''Series/DowntonAbbey'': Cora (mother of three girls) grumbles about having daughters: "you think it's going to be like ''Literature/LittleWomen'' but instead they're at each other's throats." It must have been a while since she read the book, since at least two of the little women (Jo and Amy) were ''constantly'' at each other's throats.
* ''Series/HowIMetYourMother'': Barney's "Platinum Rule" was based off his belief that the Golden Rule was "Love your neighbor." The other characters were quick to point out that it's actually "Treat others as you yourself would want to be treated."
* ''Series/MysteryScienceTheater3000'':
** Crow doing this trope is a RunningGag. Crow makes a documentary about UsefulNotes/TheAmericanCivilWar. Titled ''[[InCaseYouForgotWhoWroteIt Crow T. Robot's Bram Stoker's The Civil War]]'', it opens with this line... which is actually pretty much the film's ''high'' point when it comes to historical accuracy:
--->'''Crow''': The Civil War was a war that took place during a certain period in our nation's history. When, exactly? No one can say.
** He's also done reports about Rutherford B. Hayes ("Serving heroically in the Civil War, Hayes later admitted that it was in the army he first tasted human flesh.") and a [=PSA=] about how to treat women that mostly asserts that women are a cryptozoological phenomenon, like Bigfoot, except for the very, ''very'' end:
--->'''Crow:''' Ah. ... Oh, um, yes. So anyway Mike, in conclusion, in the off chance that you do run into a woman, uh, you know, treat her with respect and stuff.\\\
'''Mike:''' You know, Crow, you do know women. Now what about Pearl?\\\
'''Crow:''' Ok, so one woman exists. That means all women exist?
** Tom Servo is also guilty of this, in the episode ''The Skydivers''. During the prologue he puts on a planetarium show, giving us such gems as referring to the speed of light as "well over 500 miles an hour" (which is true, but in the same way it's true to say the Pacific Ocean is more than a gallon of water: the speed of light is well over 600 ''million'' miles per hour) and calling Mars "the brightest star in our galaxy."
* ''Series/NewsRadio'': Bill, while trying to stage an office rebellion, shouts, "Do you think the Pilgrims really cared about all the tea they dumped into Baltimore Harbor?" It may well be a shout-out to Bluto's speech in Film/AnimalHouse.
* ''Series/StarTrekTheOriginalSeries'': PlayedForLaughs with Pavel Chekov, who sometimes gets his Russian history wrong, claiming just about everything to be a Russian invention. That was probably what he was taught, though, as this was before TheGreatPoliticsMessUp, and the USSR in the 1960s really did have this attitude in its education.
** According to Creator/DianeDuane's novels, he's joking, as when he claims that the roller coaster is a Russian invention and is not believed he protests that this time it's true.
* [[http://www.youtube.com/watch?v=CUyK_J_W4BI This sketch]] from ''Series/ThatMitchellAndWebbLook''. Many faults are pure and simple GretzkyHasTheBall issues, but not all:
** "West Germany, famously a bunch of cheats" references ''East'' Germany's history with performance-enhancing drugs. And "Cricket? 'Ere in Yorkshire?" makes no sense as cricket is really popular in Yorkshire.
** The Ashes isn't a tournament with "second rounds" and "semi-finals". It's a revered test cricket series between the national teams of England and Australia. [[http://en.wikipedia.org/wiki/West_Indies_cricket_team The West Indies]], the Dallas Cowboys (an American football team), West Germany (a country that ceased existing for 17 years at the time of airing and in which most people have no idea what cricket actually is) and Pisswiddle Steel Batters are ineligible. Manchester United is an [[TheBeautifulGame association football]] team.
** Mitchell and Webb have a whole series of skits based on two screenwriters who never, ever, do any research. The medical drama in particular is hilarious.
-->"Now he's poorly from too much electric."
** There's also the archaeologist who makes the incredible find of an ancient Roman...videotape. It appears to show several people having a toga party, but he and other researchers talk about the incredible discoveries they're making, while [[OnlySaneMan one]] stares at them in disbelief, and eventually brings up the obvious. He's then guilt-tripped into going along with it.
* ''Series/TheYoungOnes'':
** When Rick is trying desperately to recall his history lessons, he finishes the statement "Crop rotation in the 14th century was considerably more widespread after..." with "1172". Which isn't even ''in'' the 14th century.
** Neil never sleeps because he thinks sleep causes cancer.
* Characters on ''TheWestWing'' are consistently getting called out for this; it's most always PlayedForLaughs. Perhaps the best example occurs in the pilot episode, where Sam Seaborn is asked to speak to Mallory's fourth-grade class about the history of the White House, on which subject he's clueless. Meeting them in the Roosevelt Room, he fakes it, saying the room is named after "our 18th president, Franklin Delano Roosevelt." After listening to Sam spew out factoids for a few moments, Mallory asks to speak to him outside the room:
--> '''Mallory:''' I'm sorry to be rude, but are you a moron?
--> '''Sam:''' In this particular area, yes.
--> '''Mallory:''' The 18th president was Ulysses S. Grant and the Roosevelt Room was named for Theodore.
--> '''Sam:''' Really?
--> '''Mallory:''' There's like a six-foot painting on the wall of Teddy Roosevelt.[[note]]When Sam says "our 18th president, Franklin Delano Roosevelt," the camera shows him standing ''right in front'' of that painting.[[/note]]
--> '''Sam:''' I should have put two and two together.
--> '''Mallory:''' Yes.
--> '''Sam:''' The thing is, while there really are a great many things on which I can speak with authority, I'm not good at talking about the White House.
--> '''Mallory:''' You're the White House Deputy Communications Director and you're not good at talking about the White House?
--> '''Sam:''' Ironic, isn't it?

* ''ComicStrip/CalvinAndHobbes'':
** Calvin's report on bats consists only of fluff, and one "fact" ([[ArtisticLicenseBiology bats are bugs]]) that Calvin himself made up. He's called out on it by everyone and his tiger. Bill Watterson said in a commentary that one of the nice things about writing this strip is that he didn't need to know more than a lazy 6-year-old, and after writing the story got sent more information on bats than he ever wanted to know.
** Calvin and Susie are assigned to be partners on a project about the planet Mercury. The following is Calvin's only contribution:
-->'''Calvin''': The planet Mercury was named after a Roman god with winged feet. Mercury was the god of flowers and bouquets, which is why today he is a registered trademark of FTD florists. Why they named a planet after this guy, I can't imagine. [[OhCrap ...Um, back to you, Susie.]]

[[folder:Radio]]
* A Radjo/BobAndRay sketch has Bob interviewing the author of a ''History of the United States''. It turns out that the 1,100-page tome contains numerous glaring errors, including Abraham Lincoln driving to his inauguration in an automobile, the Civil War breaking out in 1911, and the nation's original capital being located in Bailey's Mistake, Maine. The author readily admits it's "a shabby piece of work", but quickly adds that it's leather-bound.

[[folder:Tabletop Games]]
* ''Warhammer40K'': The Imperial Guardman's Uplifting Primer is hilariously filled with these, presenting the enemies of man as easy to defeat by the common soldiery. Features gems such as "ork tusks can easily be pulled out of their jaws", "the Tau are evolved from cattle and will spook at loud noises", and a magnificent illustration of a Guardsman looking around a corner like a guy who showed up early for a ScoobyStack.

[[folder:Video Games]]
* ''VideoGame/TeamFortress2'':
** Played for laughs in ''Meet the Soldier''. The Soldier starts with a (correct) quote from Sun Tzu and ''Literature/TheArtOfWar'', but then goes on to say that Sun Tzu invented fighting, perfected it, and used his fight money to herd two of every animal onto a boat and beat the crap out of them.
-->And from that day forward, anytime a bunch of animals are together in one place, it's called a '''ZOO'''! Unless it's a farm!
** In ''Meet the Director'', it's shown that the Soldier went on even more about Sun Tzu. The director had to point out that Sun Tzu never wrote books on how to punch out someone's ribcage.

[[folder: Webcomics]]
* [[http://www.closetgamers.com/comic.php?id=6 This episode]] of ''Webcomic/ClosetGamers'' contains a literal example, when a ''TabletopGame/DungeonsAndDragons'' character informs the party that a "Purple Worm" is a tiny creature eaten by harmless, flightless birds, as opposed to the giant, nasty SandWorm monster it actually is.
* From ''[[http://lolilovesvenom.livejournal.com/ Loli Loves Venom #32]]'' -- why you should not ask ComicBook/{{Venom}} for homework help:
-->''"In nature, Franchise/{{spider|man}}s have many natural enemies. There is one main predator they always have to watch out for. The mighty octopus. Their tentacles of sheer fury are fierce opponents. Only through agility, resolution, and quick banter can the amazing spider atone for the danger he faces."''

[[folder:Western Animation]]
* In one episode of ''WesternAnimation/Ben10Omniverse'', [[AnimalWrongsGroup Pax]] unleashes a tiny alien called the Screegit around Bellwood. The Screegit turns into a rampaging monster when exposed to nitrogen, but Pax thinks it'll be okay, since humans breath oxygen. Ben angrily points out that Earth's atmosphere has nitrogen in it as well.
* In the ''WesternAnimation/HomeMovies'' episode "History", Brendon makes a movie with George Washington, Annie Oakley, and Pablo Picasso as the primary villains, with very obvious inaccuracies for their backstories (such as Washington freeing the slaves, Picasso cutting off his ear, etc.). It's later revealed that he's been receiving tutoring from Coach [=McGuirk=], and he's flunking history.
* In a likely nod to the ''Film/AnimalHouse'' example above, TJ from ''WesternAnimation/{{Recess}}'' once made a speech to convince Gretchen to not give up on the "space travel training" the gang was putting her through:
-->"Did ''Albert Edison'' give up when they stole his Theory of Regularity? Did ''Ben Franklin'' give up when the Germans shot down his kite?"
* ''[[WesternAnimation/TotalDrama Total Drama World Tour]]'':
** The intern responsible for doing the research comes up with [[AncientGrome Rome, rather than Greece]], as the birthplace of the Olympic Games. He is [[YouHaveFailedMe fired by Chris, the host of the show]], when the mistake is pointed out... by being shoved out of the plane.
** [[BrainyBrunette Courtney]] tried correcting Chris when the contestants were in China, and he told them the Great Wall was built eight million years ago. The kicker? Even though Courtney realized the Great Wall couldn't have been built until much more recently, she explained there were ''dinosaurs'' in 8,000,000 B.C. Probably joking?
* In ''WesternAnimation/TheSimpsons'', Bart calls a bunch of countries in the Southern Hemisphere to see which way the water flows in their toilets and drains. Among them is apparently Burkina Faso. This might actually be justified since Bart isn't exactly the brightest tool in the shed.
