This is a particular instance where a story or character has something - a statement, the depiction of something - that is so egregiously off-the-scale in terms of inaccuracy that anyone with a high school education and/or 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.

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

!!Unintentional Examples

* A TV spot for the film ''Film/{{Gamer}}'' became an Internet hit when it claimed that "the last time Creator/GerardButler kicked this much ass was Film/ThreeHundred years ago." [[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'''.

[[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.
* A ''Anime/LupinIII'' episode had a sign marking the Kansas/Washington D.C. border. Was it that hard for the writers to get a map of the United States?

[[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 Prisoners 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.
** Also, Tintin's surprise that Incas still exist. The Incan ''empire'' fell centuries ago, but they still exist as a distinct people.
* 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 check on what 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]]. {{Averted|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:Fan Works]]
* ''FanFic/DumbledoresArmyAndTheYearOfDarkness'': If Thanfiction knew enough about Demiguises to include them in DAYD, he should have known enough about them to not portray them as invisible ''goats'' when they're invisible ''apes''.
* In ''Fanfic/MoonDaughter'', the author classifies dryads and satyrs as monsters. Also, [[MarySue Flavia]] claims that Literature/{{Percy Jackson|AndTheOlympians}} killed Luke.
* ''Fanfic/MyLittleUnicorn'': Dakari-King Mykan gets the most basic facts about ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' wrong. The author believes Rainbow Dash has magic and doesn't know who Derpy Hooves is.
* 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, [[EstablishingCharacterMoment 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.)
* SupperSmashBrosMishonhFromGod shows various examples in relation to the games that Smash Bros are based upon. The most egregious examples are in 'The REEL Sekwel', where she believes VideoGame/{{Pacman}} is a Franchise/{{Pokemon}} and [[VideoGame/FZero Captain Falcon]] is a villain in FireEmblem.
* [[https://tellygunge.wordpress.com/archives/story-archive/by-tellygunge/ Tellygunge's]] [[RealPersonFic celebrity fics]] will often involve a scene where a character getting [[CoveredInGunge gunged]] suffers a WardrobeMalfunction (or a PantyShot) at some point, and the narrative [[ShowDontTell making a remark about how it would become a YouTube hit.]] Except that it wouldn't because nudity is banned on [=YouTube=].[[note]]While it is true that the rules are often ignored by users, they would still be enforced for a viral hit because the large amount of views would cause [=YouTube=] to take notice of it.[[/note]] From the policy centre:
-->''Videos containing fetish content will be removed or age-restricted depending on the severity of the act in question. In most cases, violent, graphic, or humiliating fetishes are not allowed to be shown on [=YouTube=].''
-->''A video that contains nudity or other sexual content may be allowed if the primary purpose is educational, documentary, scientific, or artistic, and it isn’t gratuitously graphic. For example, a documentary on breast cancer would be appropriate, but posting clips out of context from the same documentary might not be.''

[[folder:Films -- Animation]]
* The film ''WesternAnimation/{{Foodfight}}'' features main character Dex Dogtective, an [[PettingZooPeople anthropomorphic dog]] whose TrademarkFavoriteFood is raisins. It's a good thing that ''Foodfight!'' [[BoxOfficeBomb was seen by about six people]], because raisins are poisonous to dogs.


[[folder:Films -- Live-Action]]
* ''Film/TheAmazingColossalMan'' features a ''scientist'' who claims that "the heart is made up of a single cell."[[note]]They probably got the "single cell" thing from the fact that heart muscle is ''syncytial'', which means that its cells are not separated by membranes.[[/note]]
* 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 writer of ''Film/CourageUnderFire'' admits that when he wrote the script, which involves a female military officer who died in the first Gulf War becoming "the first female Medal of Honor recipient", he didn't even bother to check whether or not there already was a woman who had that honor. Turns out that Captain Mary Edwards Walker, a US Army doctor, won the award during the Civil War, some 130+ years before ''Film/CourageUnderFire'' was set, when she refused to leave patients she was treating despite the fact that her field hospital was being actively shelled by the confederate army.
* 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.
* 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.
** Any and all films in the ''Franchise/{{Godzilla}}'' franchise can be expected to turn out half a dozen examples of this trope when trying to explain how Godzilla can exist. [[ILoveNuclearPower Nuclear bombs]] inevitably play a large role in his presence.
* In ''Film/TheMatrix'' Morpheus's exposition that people are kept in suspended animation because they were 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. Then again, ''batteries'' are used for ''storing'' energy, which makes more sense than the common interpretation of Morpheus' line (that humans were used to ''generate'' energy).
** Agent Smith mentions his contempt for humans, claiming that humans are the only creatures that don't instinctively seek an equilibrium to stop population growth, saying they are more like parasites than animals. Many animals have gone extinct through overpopulation, when something happens to the population of their predators.
* 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 a slightly more esoteric Critical Research Failure, ''Film/NumbersStation'' has the transmissions being read live by a real person, who's also the one doing the encoding--in her head, for all that she has a perfectly good computer on her desk. Modern NumbersStations only use live readers if their voice synthesizers break, and it would be a critical ''security'' failure to allow anyone who's ever seen leaving the bunker to see the clear-text versions of the messages. Plus, a computer can do the encoding much faster, and with no possibility of error.
* 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." 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." (Then again, considering cats, it may have been humor on Ruth's part.)
* 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'.
* Another Emmerich film, ''{{Film/Anonymous}}'', has Edward de Vere show off his garden bush of Tudor roses... [[http://en.wikipedia.org/wiki/Tudor_rose a flower that has never existed as a real plant, only a figurative symbol]]. It's an error that must have been impossible for the director to ignore, since if the plant does not exist, a faked one must have been put onscreen. If they had to make a fake one, then why are they claiming it's a real flower in a film that claims to be based on history?!
* In ''Film/{{Eraser}}'', Dr. Cullen (played by Vanessa Williams), apparently a physicist, explains that a railgun fires "caseless aluminum shells ''at nearly the speed of light''." Railguns are magnetic, so the slugs need to be a ferrous metal, and approaching the speed of light with one is ... well, it's exactly as hard as with everything else.
* ''Film/JupiterAscending'': At one point Jupiter uses a maxi pad as a makeshift band-aid for Caine's wound. That in and of itself is not a bad idea. Problem is, she applies ''the sticky side'' to the wound, not the other side actually designed for absorbing blood. One would think her actress Creator/MilaKunis would know herself which side does which.
* ''Film/{{Chocolate}}'': Zen, the autistic protagonist, becomes a competent fighter by watching martial-arts movies. But autism tends to impair motor skills. So even if Zen ''wanted'' to be a fighter, she'd have a hard time with it, and she'd be nowhere near as talented as she appears to be.

* ''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. He actually got something backwards here: it was Aztec religious leaders who jumped on board with communion. They would occasionally cannibalize sacrifice victims to obtain the dead person's powers, so a ceremony eating a god appealed to them.
* 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.[[note]]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. [[/note]]
* 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/{{Doctor Who|Expanded Universe}}'' 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'': Col. Graff says 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.
* ''Literature/TheFaultInOurStars'':
** Gus whines about how there are no paintings of people who die of diseases. Paintings depicting exactly that are very common, in fact the bubonic plague (one of the diseases Gus specifically mentions) was one of the most common motifs during the 14th through 18th centuries.
** Gus claims to feel kinship with [[Literature/TheDiaryOfAYoungGirl Anne Frank]] because he's ill from cancer and she died of illness. While ''technically'' he's not wrong (Anne died of tuberculosis), ignoring the [[UsefulNotes/TheHolocaust pretty major awful state-sponsored-genocide part]] that was the cause of it and treating it like another death by bad luck (which is what the title refers to) comes off as incredibly ignorant. It'd be like claiming Abraham Lincoln died of a brain haemorrhage and ignoring the "shot by an assassin" part.
* The ''[[Literature/FiftyShadesOfGrey Fifty Shades of Grey]]'' series could be the poster child for this trope. In addition to James' incorrect depiction of BDSM (she doesn't seem to grasp that the sub's consent every step of the way matters, that Christian Grey's constant state of rage does not indicate self-control at all, or that any alleged dom who lashes out at his partner in anger as he so often does would be blacklisted by those in the Lifestyle), she also gets numerous other things wrong, such as:
** Ana driving south from Vancouver, Washington to Portland, Oregon to get to Seattle, Washington (which is ''north'' of Vancouver, Washington).
** In ''Fifty Shades Darker'', Grey's personal private investigator tells him that [[PsychoExGirlfriend Leila]] [[BrokenBird Williams]] has obtained a concealed-carry permit for a gun. Ana concludes (and Grey agrees) that this means that Leila can simply buy a gun. A concealed-carry permit has nothing to do with whether someone can buy a gun. Second, when it comes to concealed weapons—and by the way, there are states where having pepper spray in your purse is considered "carrying a concealed weapon"—Washington state is what is known as a "shall-issue" jurisdiction. That means that yes, you can get a concealed weapons license—but you have to meet very strict criteria. [[http://www.dol.wa.gov/business/firearms/faconcealreq.html Leila does not qualify for five reasons]]: she is on record as Christian's stalker, and has been for a year; he has a restraining order against her and she's not supposed to come anywhere near him; she has been involuntarily committed to a mental institution; she is a fugitive from ''two'' mental institutions; and she's been on suicide watch since Grey broke off the relationship with her.
*** Also, in Washington state, Leila needs the following just to ''apply'' for a concealed-carry permit: a valid, government-issued photo identification (for example, Washington driver license or ID card). If you don’t have a Washington State driver license or ID card, you must provide proof you have lived in the state for at least the last 90 days. Well, Leila has neither a Washington driver's license nor a state ID, and not only hasn't she lived in the state for ninety days, she's a fugitive.
*** That's leaving out the problem of her buying the gun legally in the first place.
*** And just to apply for a concealed-carry permit, Leila the Fugitive would have to walk into a county sheriff's office or a town/city police department. The sheriff or cops would fingerprint her and and do a background check. For a non-resident of Washington, that would take about sixty days. Yet she is supposed to have obtained the concealed-carry permit the day before...despite having first been confirmed to have been in the state the previous Thursday. The timeline just doesn't fit.
** And then there are Grey's technological failures. For example, Ana says in ''Fifty Shades Darker'' that Grey is "intent on being first to market with a wind-up mobile phone." Well, he's not going to succeed. Know why? [[http://www.gizmag.com/ulysse-nardin-mechanical-mobile-phone/11228/ Because Swiss watchmakers Ulysse Nardin teamed up with European company SCI Innovations to develop the world’s first mechanical mobile phone...in 2009]]. It's 2011, in-universe. He's trying to develop something that's already in ''existence''.
** Mia Grey, Christian's sister, tells Ana in ''Fifty Shades Darker'' that he was expelled from two different schools for beating up other students. There would have to be a hearing before expulsion, and his parents would have to specifically waive the hearing—which it's unlikely his lawyer father would do. And if there was a hearing, [[http://apps.leg.wa.gov/wac/default.aspx?cite=392-400-285 here are all the rights Christian would have had]]. Expulsion's not casual and it doesn't happen instantly. [[http://apps.leg.wa.gov/wac/default.aspx?cite=392-400-310 There's also an appeals process]].
*** And then...here's the reason for keeping a kid out of school in Washington state while he's appealing his expulsion. The kid is "[[http://app.leg.wa.gov/WAC/default.aspx?cite=72-120-210 an immediate and continuing danger to the student, other students, or school personnel or an immediate and continuing threat of substantial disruption of the educational process of the student's school]]." So Grey being expelled isn't a matter of "Aww, poor sad disturbed boy." It's a question of "too dangerous to have in school." That says a lot about Christian Grey that James probably didn't intend to say.
** And there's this quote from Chapter 19 of ''Fifty Shades Darker''. For the record, Christian Grey is speaking. "Ros had never seen Mount St. Helens, so on the way back [from Portland, Oregon] as a celebration, we took a quick detour. I heard the TFR was lifted a while back and I wanted to take a look. Well, it’s fortunate that we did. We were flying low, about two hundred feet AGL, when the instrument panel lit up. We had a fire in the tail—I had no choice but to cut all the electronics and land.” He shakes his head. “I set her down by Silver Lake, got Ros out, and managed to put the fire out."
*** A TFR is a Temporary Flight Restriction. There were no Temporary Flight Restrictions on Mount St. Helens for all of 2011, when this book is set. There were none for all of 2009, either, when E.L. James wrote the fanfic ''Master of the Universe'' on which the Fifty Shades trilogy is based. The most recent TFR in effect around Mount St. Helens--that Christian Grey would remember, anyway--was in 2008...three ''years'' before the timeline of the book.
*** Also, wouldn't a responsible pilot who didn't know if there was a flight restriction on an area call a local airport and ask?
*** AGL. The acronym stands for Altitude Above Ground Level. And you need to know the MSL—Mean Sea Level—in order to figure it out. [[http://answers.yahoo.com/question/index?qid=20070419160759AA16nE3 To find out your approx AGL you would take the elevation of your closest airport and subtract it from the altitude on your altimeter (MSL)]]. AGL = Mean Sea Level - Elevation. The closest airport to Silver Lake, Washington is Southwest Washington Regional Airport, also known as Kelso-Longview Airport; it's 57 miles (or 92 kilometers) away. Kelso-Longview's elevation is 20 feet. According to Christian, the AGL was 200 feet. So the equation would look like this: 200 = Mean Sea Level – 20. Therefore, Mean Sea Level must be 220 feet. That's about as high as a twenty-five-story building. Not really a problem, right? Well...
**** [[http://www.ecfr.gov/cgi-bin/text-idx?c=ecfr&sid=82a3ff470c98b92227cdd83d35adffc9&rgn=div8&view=text&node=14: According to the FAA, the minimum safe altitude for helicopters in a congested area—cities, towns, settlements, or open air gathering places like campgrounds, bandshells, arenas, stadiums, etc.— is an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft]]. There are three cities within fifty-one miles of Mount St. Helens (Longview, Washington, Vancouver, Washington, and Portland, Oregon), two of which have populations of 150K or more, making Mount St. Helens a congested area. Which means he should have been a thousand feet higher than the highest obstacle. That would be Mount Adams, which is about thirty-four miles east of Mount St. Helens. [[http://www.dartmouth.edu/~volcano/texts/DekMtStHelen.html Mount St. Helens is 8,365 feet high]]. [[http://volcanoes.usgs.gov/volcanoes/adams/ Mount Adams is ''12,277'' feet high]]. And it's a volcano as well. If Christian Grey didn't want to smash into ''the largest active volcano in Washington'', he should have been at least ''13,277'' feet up.
* 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.
* 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.
* 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 Chapter 19 of ''New Moon'', we get this passage about St. Marcus Day in Volterra, Italy: ''[Alice Cullen] chuckled darkly. "The city holds a celebration every year. As the legend goes, a Christian missionary, a Father Marcus — Marcus of the Volturi, in fact — drove all the vampires from Volterra fifteen hundred years ago. The story claims he was martyred in Romania, still trying to drive away the vampire scourge. Of course that's nonsense — he's never left the city. But that's where some of the superstitions about things like crosses and garlic come from. Father Marcus used them so successfully. And vampires don't trouble Volterra, so they must work."''
*** First, there was no 'Christian missionary to Volterra' in the fifth century A.D. ''There was no need for one.'' Catholicism--it hadn't split into Roman Catholicism and the Greek Orthodox Church yet--was legalized by the Emperor Constantine in 313 A.D. (or Common Era, if you prefer). And it became the state religion of the Roman Empire in 382 A.D. As a matter of fact, [[http://www.turismo.intoscana.it/intoscana2/export/TurismoRTen/sito-TurismoRTen/Contenuti/province/PI/volterra/visualizza_asset.html_198747442.html during the fifth century CE, Volterra was the residence of a bishop]], and [[http://toscana.indettaglio.it/eng/comuni/pi/volterra/volterra.html the bishops kept that power in Volterra until the twelfth century]].
*** Second, Volterra ''does'' have a celebration every year in honor of their patron saint--[[http://www.tuscantour.com/tours/events.php San Giusto]]. St. Justus, it would be in English.
*** Third, the celebration isn't centered on the cathedral. There's a parade, a tug-of-war, and a city-wide foot race where participants hold lit candles while they run.
*** Fourth, it doesn't happen on March 19th, either--which is [[http://www.calendar-updates.com/info/holidays/us/stjoseph.aspx Saint Joseph's Day]], by the way. It takes place on June 5th, probably because the weather is nicer on that day than on Saint Justus's ''real'' feast day--[[http://saints.sqpn.com/saint-justus-of-trieste/ November 2nd]].
*** Fifth, Volterra's actual patron saint doesn't have a thing to do with vampires--not in his life, and not as a patron saint invoked against them. This is significant, because some saints are enemies of vampires. [[http://en.wikipedia.org/wiki/Saint_Roch St. Roch is prayed to in Poland to keep vampires at bay]]. And [[http://en.wikipedia.org/wiki/Gello#Gello_and_her_adversaries St. Sisinnius, the Virgin Mary and the Archangel Michael are invoked against the gello (a special kind of vampire-demon that steals and eats children)]].
*** Sixth, St. Marcus could not have been martyred in Romania in the fifth century CE, because Romania didn't EXIST then. Romania was formed from the provinces of Moldovia and Wallachia in 1859 and was named Romania in 1866. In the fifth century, the area would have been divided into two regions: Dacia Ripensis (a military province) and Dacia Mediterranea (a civil one). Dacia Ripensis flourished particularly well, becoming the birthplace of a noted fourth-century Christian theologican. Then it was captured in the 440s--the fifth century, in other words--by the Huns.

[[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 ''Awesomeness TV'' sketch "Terry the Tomboy" got the "tomboy" part completely wrong. Apparently the showrunners think "tomboy" means "redneck stereotype".
* One episode of [[Series/TheBigBangTheory The Big Bang Theory]] has Sheldon wanting to become friends with his [[SitcomArchNemesis rival]] Kripke because Kripke could grant him access to special equipment. He goes to a book store and asks for books about making friends, and is told that all those books are in the children's section. Apparently the writers have never heard of the world famous book "How to Win Friends and Influence People," or the concept of self help books in general.
* 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...
* ''Series/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.
* 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/TheFlash'' episode "The Sound and the Fury" is full of chess metaphors, but the actual game between Harrison and Hartley disregards the rules. Harrison, in check, moves his rook in front of Hartley's king, which is illegal because it doesn't remove the threat to his own king. Even if it were legal, it would only put Harley in check because Hartley could have taken Harrison's rook with his knight.
* ''{{Series/Forever}}'': In "Hitler on the Half-Shell", we see Henry's flashback to 1812, where he learned his father was involved with the slave trade. However, it had been abolished in 1807, and there's no indication this is illegal trading.
** This builds on the error in the pilot episode, in which Henry is shown on a ship carrying a black man described as "property" some time after 1814 (Henry narrates his first death as "almost two centuries ago" speaking from 2014). To add insult to injury, the ship is flying an out of date British merchant ensign - the ensign clearly lacks the cross of St Patrick, which was added to the flag in 1801 after the Act of Union with Ireland.
** In "The Man in the Killer Suit" the fake aristocrat claims that he's not a Lord, he's a Viscount. Despite the fact that a Viscount is ''by definition'' a Lord. His fake passport also, incorrectly, contains the title "Viscount". Given the amount of research the woman training him did to help him with his role, you'd have thought she'd spend five minutes checking Debrett's, which would have prevented these errors. Then again, they were trying to fool Americans, who are not known for their detailed understanding of the British aristocracy, as the episode does acknowledge, so this could just be Truth in Television.
* ''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 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.
* 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 fewer 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.]]"
** A viewer wrote that the average life expectancy in Canada is higher than in the US. Bill replies that this is only natural... then makes a statement that would fit right in as a "spot the flaw in the logic" problem in an elementary school math class: 'The [=USA=] has ten times as many people as Canada, leading to ten times as many violent crimes and accidents, leading to a lower average life expectancy.'
* 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''.
** Though in fairness, the ''Aeneid'' does at least feature the rescue of Helen (as part of the flashback in book 2) whereas the ''Iliad'' ends before the rescue of Helen. And the ''Iliad'' is specifically stated from its opening line to be about the Wrath of Achilles.
* ''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 (They might have mistook meters for yards)[[note]] Although, in RealLife, Creator/PatrickStewart isn't even that tall [[/note]]. Joked about in Picard's last appearance, ''Film/StarTrekNemesis'' -- Picard and his clone both lament not having reached two meters in height.
* ''Series/{{Supernatural}}'': In an early second-season episode, John Winchester's blood type is shown on his dogtags as AB (though no Rh factor is given). Early in Season Ten, Dean's blood type is established as O...which is the one type it ''can't'' be if he's John's son, because A and B are both dominant and he has to have inherited one or the other. Either it's Critical Research Failure or [[YoureNotMyFather Dean is not John's biological son]]. Which makes you wonder what would've happened if he'd ever [[spoiler: said yes to Michael]].
* ''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.
* In ''Series/AgentCarter'', the title character immediately decrypts an encoded message after realizing it uses a "one-time pad system." The thing about one-time pads is that, if done properly, they are ''absolutely impossible'' to decipher without the key, period. Even assuming that the message Carter decrypted wasn't generated properly, it still should have taken some time to decrypt it.

* 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 most bloodthirsty 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?)
* [[UsefulNotes/ArabIsraeliConflict Hamas]] released a video clip in late 2014 for a propaganda song in Hebrew meant to scare Israelis titled ‘[[https://www.youtube.com/watch?v=DSvGbYUIaaM We Shall Take the Zionists to the Gallows]]’. Aside from it being incredibly {{Narm}}y in general, the chorus mentions that resistance movements that existed prior to the foundation of the State of Israel have bitten the dust. The only problem is, not only were they mostly concerned with ending the British Mandate, not fighting the Arabs, they were disbanded by the State of Israel itself to form the IDF, making this about the most idiotic BadassBoast they could think of.

[[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 one strip of]] ''Webcomic/SquareRootOfMinusGarfield''.

[[folder:Pro Wrestling]]
* Wrestling Hockey Players, The Ballard Brothers, took up a valet to serve as their Wrestling/{{Cheerleader| Melissa}}, even though hockey doesn't make use of cheerleaders. This could be excusable but the Ballards are Canadian, so there really is none.
* Wrestling/VinceMcMahon, pleased with the success of Wrestling/ReyMysterioJr on Smackdown, decided he wanted another flippy luchador. So he hired Wrestling/UltimoDragon and then got upset when he discovered Ultimo Dragon really was not all that flippy. This is despite the fact Ultimo Dragon had wrestled under the WWF banner before and won a WWF championship, suggesting Vince did not even watch his own product.

* 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:Tabletop Games]]
* The ''TabletopGame/DarkSun'' setting was originally designed as taking place on an icy frozen world. During development, it was changed to a desert world because the developers thought that a warm climate would justify {{fanservice}}y art with {{Stripperific}}ally-dressed characters. Showing that much skin is just as dangerous in a desert as it is in the cold because it leaves the body open to sunstroke and allows for more water loss from perspiration, as evidenced by how actual desert-dwelling peoples traditionally dress in long, flowing robes that cover the entire body.
* 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]]. Or, even more more accurately, [[ScienceMarchesOn birds are dinosaurs with (perhaps) a few more feathers.]]
* 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.
** Particularly infamous is the ''Space Phenomena'' themed deck. Amongst other glaring errors, it states that the ''Moon'' was spotted in '''1651''', Ganymede was discovered before the Sun, and asserts that Halley's Comet has negative mass. Somehow.

* 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 star 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.

[[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.[[note]]Though this has its own problems; while there certainly are automatic weapons that can fire at this rate (the M134 minigun, for example), they're not hand-carried. An M134 goes through a couple of pounds of ammunition a second, meaning that unless you're so loaded down with ammo you can barely move, a few seconds into the fight you're going to have what basically amounts to a very expensive club. 100 rounds per minute is extremely unimpressive for a fully automatic weapon (it's only around twice as fast as a decent semi-automatic rifle), but at least you wouldn't run out of ammo so fast.[[/note]]
* In the PSP game ''VideoGame/{{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 [[note]]which isn't entirely true either; Normal is weak to Fighting but mutually immune to Ghost[[/note]]. The writers ignored the defensive benefits of those Pokémon's typings, and three of the six Pokémon they mentioned this on can learn moves of their type by TM [[note]]Sandslash and Rhydon get Earthquake/Dig, while Hitmonchan gets Submission[[/note]].
* 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, and 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) [[UsefulNotes/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..."

* ''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.

** In their video about sexuality, they talk about how tired the trope of a tough male with a feminine side is. As an example, they show ''VideoGame/FinalFantasyXIII'''s Lightning, who anyone looking at the character can tell you is ''female''.
** They also mention in their "Transgaming" episode that the Pokémon in the TV show function like the Pokémon in the game - except that the TV show on a regular basis ignores the rules of the games, and this happened as early as the Kanto season.
* ''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.]]
* In ''20 Reasons Why NOT to Be "In Da Club"'' by [[WebVideo/MatthewSantoro Matt Santoro]], Matt says that if you're at a club and you fall anywhere, you should just assume you have AIDS or herpes, because of all the broken glass lying around. In reality, falling on broken glass lying around is extremely unlikely to give you AIDS, as that has only happened a few times.
* ''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.
* 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 (and the reason the Elites jumped to humanity's side was because the Brutes and Prophets enacted ''genocide'' against them); hardly a shining example of ethnic diversity.
* The creature, the [[GratuitousJapanese Kiseichu]] [[http://legendaryeon.deviantart.com/art/Kiseichu-Ryu-482690667 Ryu]] is said to be a Carnivore at birth (after devouring from dead criminals), then a Herbivore for the rest of its life. Animals cannot switch diets at will; the stomach for both Carnivores and Herbivores, and their digestion system are not the same thing, meaning that they could most likely die of malnutrition.
* ''WebOriginal/GameTheory'' infamously claimed Wario was ten feet tall, a deduction based on an incorrect calculation from an earlier episode, a calculation that in itself relied on rather shaky evidence. Mat Pat would later make the statement a RunningGag for his other research mistakes.

[[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 that's not mentioned at all. South Africa, Singapore, Cote d'Ivoire, Central African Republic, San Marino, Vatican City, and various countries in Oceania (such as Samoa or Tonga) are also not mentioned, and Transylvania is mentioned as a separate country from Romania.
** Also, the Korean peninsula is made up of two separate countries: The Republic of Korea and the [[PeoplesRepublicOfTyranny 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.
** Dan freaks out when he unthinkingly drinks a milkshake, thinking he will die. In actuality intolerance to lactose isn't fatal (worst case scenario, he'll have a bit of gas and possibly [[BringMeMyBrownPants need a change of underwear]]--plus, a couple of swallows of dairy might not even do anything if one's lactose intolerance is fairly mild. Of course, Dan tends to be a drama queen.)
* ''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 Brian mentions about how there was no war before "religion", a cutaway shows friendly men fighting each other immediately because Jesus was born, even though of course wars happened ''before'' Jesus was born. Not to mention the fact that Brian apparently thinks there were no other religions before Christianity.
* Maybe it's a case of creative liberty, but the Al Brodax {{Popeye}} cartoon "I Yam Wot I Yamnesia" posits that if two people bump heads with each other, they switch personalities and voices. Wimpy diagnoses this as amnesia.
* In the ''WesternAnimation/JusticeLeague'' finale, Clark ask the Thanagarians about the machine they're building 'in the Gobi desert'. Later, the location shows up on the Watchtower's radars in northern Africa. That's the ''Sahara'' Desert - the Gobi is in eastern Asia.

!!In-Universe examples

[[folder:Anime & Manga]]
* Generally, ''Manga/DetectiveConan'' avoids these issues by Aoyama doing [[ShownTheirWork research]], off and on there are instances where the reasoning for even simple things in the series just don't make sense. One instance is when Ludger, a German character, appears and he speaks near-perfect Japanese. Conan deduces that his wife is British because Ludger referred to the restaurant being on the 2nd Floor, when it would be the 3rd Floor in Japanese, and that this is because the British refer to the 1st Floor of a building as the Ground Floor and then begin to count number-wise upward. Problem is that '''Germans''' do that, too, so his reasoning is faulty since Ludger, being German, automatically counts floors in the German fashion, making Conan's elaborate reason why his wife must be British obsolete.

[[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]]
* ''SupplementalMaterial/TeamFortress2'' comics:
** In ''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 lead-contaminated water for over a generation.]]

[[folder:Comic Strips]]
* ''ComicStrip/CalvinAndHobbes'':
** Calvin has to do a report on bats, but being the typical lazy six-year-old that he is, he does absolutely no research on them. He assumes bats are bugs because "they fly, right? They're ugly and hairy, right?" Despite literally everyone who hears this telling Calvin that bats aren't bugs, he refuses to listen. Predictably, he fails the assignment. 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, which he wrote the morning before class despite having a week to work on his report:
-->'''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:Fan Works]]
* 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.
* In an in-universe example, the LemonyNarrator of ''Fanfic/EquestriaAHistoryRevealed'' 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]]).
* ''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.
* Used intentionally and PlayedForLaughs in the ''Literature/{{Twilight}}'' fic ''[[https://www.fanfiction.net/s/5549437/5/Third-Wheel Third Wheel]]''. (The narrator is something of a ditz.)
-->''[Discussing Bella Swan's family]'' So the acorn didn't fall too far from the pine tree.
* In ''FanFic/WithThisRing'' InUniverse example with Senator Knight's proposal to ban magic after the ''''deaths of thousands of children'''' in '''Displaced'''. Senator Knight didn't know that literally anyone can learn magic and he could found this out by asking Zatara, a Justice League member with a public adress who is a magic specialist. His name became synomous with obliviousness and ignorance when Orange Lantern calls him out on it in a live interview.

[[folder:Films -- Live-Action]]
* 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!"\\
"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.]] Sharp-eyed fans have noted that's not the only thing wrong with the scene. The woman's hair is wrong, her attire isn't quite period-appropriate, and so on... and so they've theorized the many minor mistakes is that Nick Fury wanted to know how much sharpness Captain America lost during his long sleep.
* 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: "Our source was ''The New York Times''."
* 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"). 47, not the slightest bit intimidated, points it out to him.
* ''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.\\
'''Coleman:''' Sweden? ...But you're wearing ...Lederhosen.\\
'''Ophelia:''' [[RefugeInAudacity Ja, 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.

* ''Literature/ASeriesOfUnfortunateEvents'':
** The villains of ''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.
** Earlier in the same book, Esme defines "individual practitioner" as "a life of crime". Even baby Sunny knows that she's completely off the mark (and, funnily enough, provides the correct definition).
* ''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 the 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."
* In Creator/StephenKing's novella ''The Body'', the 12-year-old protagonist wrote a bunch of stories about Americans trying to take a French town from the Nazis... in 1942. Only two years later did he find out that the Allies didn't land in France until 1944.

[[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. In reality 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.
* One scene from ''Music/FlightOfTheConchords'''s HBO series has a racist fruit vendor mistake Australian stereotypes for New Zealander ones.
-->'''Jermaine:''' I'm a person. Bret's a person. You're a person. That person over there's a person. And each person deserves to be treated like a person.\\
'''Vendor:''' That's a great speech. Too bad New Zealanders are a bunch of cocky a-holes descended from criminals and retarded monkeys.\\
'''Jermaine:''' Hey you're thinking of Australians.\\
'''Vendor:''' No no no, New Zealanders, "throw another shrimp on the barbie", ride around on your kangaroos all day.\\
'''Jermaine:''' No, no no, that's Australians. You're thinking of Australians; that's not us.\\
'''Vendor:''' I've totally confused you with Australians, I feel terrible. It's just your accents are just kinda similar.\\
'''Jermaine:''' Our accents are completely different. They're like: "Where's the ''cahh''?" and we're like "where's the cahh?".
* ''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.
* Baroski correcting the ''Series/SonsOfAnarchy'' on the use of the term "Persian" is both intentional and unintentional. The country has officially been called Iran by the West since 1935 and by the East long before that. However, some of its people culturally self-identify as Persian. It would be acceptable to call the pornographers Persian if they identify as such, but it's never made clear if this is the case. If the Sons are also unaware, it would be better to refer to them as Iranian. Baroski's claim that "Persia hasn't been a country since 637 AD" is incorrect; the Persian Empire fell that year, but that doesn't mean it ceased to exist as a country.
* ''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 ArtisticLicenseSports, 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 ''Series/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. In fairness to Sam, there's also a painting of FDR in the room, although traditionally only one of those paintings is hanging at a time, depending on the current president's affiliation.[[/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?
::He has a point. He deals with political messaging. The person to ask for information about the White House as a building would be a tour guide, which means that whoever decided he needed to talk to the class about it had their own failure.

* MC Historical Inaccuracy's verse in Creator/JonLaJoie's [[https://www.youtube.com/watch?v=EbAJivTHPoQ WTF Collective 2]] is based on this trope. It's better heard than read, but here are the lyrics:
-->Yo, I'm MC Historical Inaccuracy
-->I drop lyrical bombs like Hiroshima in '73
-->I write rhymes like Shakespeare when he wrote Anne Frank's Diary
--> Which is about the Civil War of 1812 in Germany
-->I'm like the Spanish Inquisition when they killed Jesus

* 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.

* ''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. Those are actually partially true, though. Orks have shark-like teeth that are constantly being shed and could conceivably be pulled out fairly easily while the Tau are descended from grazing ruminants and display many vestiges of that past (spooking at [[MagneticWeapons loud noises]] NOT being one of them). Indeed, a common theory is that the Primer is lying to you on purpose ("[[TooDumbToLive Genestealers are slow and sluggish]]") in order to raise morale. Any company worth even half its salt has a few units of Veterans who know what fighting in a CosmicHorrorStory is ''really'' like.

* ''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.
--->'''Soldier:''' And from that day forward, anytime a bunch of animals are together in one place, it's called a '''TZU'''! ...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.

* [[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:Web Original]]
* In ''WebVideo/ThirdRateGamer'', the Third Rate Gamer gives us many examples, such as claiming that the ''Film/SuperMarioBros'' film is the original and the [[VideoGame/SuperMarioBros1 game]] is just a cheap licensed cash-in.
* Website/YouTube channel ''[[https://www.youtube.com/channel/UCpvtp7mH0Cdq8FQUxcjDq0Q My Life in Gaming]]'' occasionally invokes this in their {{Retraux}}-style "How to Beat" videos, such as by mispronouncing terms and by getting the backstory of ''VideoGame/SuperMario3DWorld'' wrong, to mirror the errors that often occurred in the '80s-era "how to beat" VHS tapes that the series is imitating.

[[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 breathe 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:
-->'''TJ:''' 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 solid with the book-learnin'.
* ''Series/{{Futurama}}'' refers to the ''[[Film/TheMatrix Matrix]]'' example given above, with Bender saying "Doesn't that violate the Second Law of Thermodynamics? Wouldn't just about anything make a better battery than a human? Like a potato? Or a ''battery''?" Leela explains that while everyone at the time it was made thought ''The Matrix'' was the worst movie ever because of this "mistake", it turns out the film actually got it right. Of course, this is a universe in which it's possible to travel between stars in hours or at most days because "scientists increased the speed of light in 2208," not to mention that in the real world, the original movie is still roundly considered very good by most people who have seen it.

[[folder:Fan Works]]
* ''FanFic/Gensokyo20XX'' almost has on a meta-level when it comes to Tosca, an opera she alluded to the author initially thinking it was by Shakespeare. Fret not, she later corrects her mistake both in RealLife and in-universe.
