Context IdiotBall / Literature

Go To

1* Literature/AesopsFables: In "Literature/TheTortoiseAndTheHare", the hare has a massive lead in the race against the tortoise, and could easily win. So what does he do? He ''takes a nap'' in the middle of the race, and as you'd expect, he wakes up just in time to see the slow and steady tortoise about to cross the finish line.
2* ''Literature/TheBriefWondrousLifeOfOscarWao'': Oscar is portrayed as fairly intelligent in most of the book, but his decisions in the last section (namely [[spoiler: returning to the Dominican Republic and continuing to pursue a woman with a cop boyfriend who had him ''beaten almost to death'' when he hung out with her before]]) are almost unfathomably stupid.
3* In ''Literature/ABrothersPrice'', Corelle. "My mothers and elder sisters are away, and told me to not leave the farm, not even to mend the fence ... guess what, I'll go and visit the neighbour boy, and take the other middle sisters with me ... after all, what could ''possibly'' go wrong?" Yeah. What could happen is that some bandits who have no qualms about [[MoralEventHorizon killing men]] pass by, and Corelle's innocent virgin brother has to go out, only guarded by a preteen sister, and carry a strange woman who was wounded by the bandits to safety.
4* If the kids in ''Literature/CharlieAndTheChocolateFactory'' were firmly holding on to a bunch of Idiot Balls, what with they messing with industrial contraptions and ignoring warnings despite having seen what happened to the kids before them, Charlie's grandparents (except for Grandpa Joe) in ''The Great Glass Elevator'' swallowed about a locker's worth. After being invited to tour the factory, Willy Wonka offers the three of them (who, by the way, are ''still in bed'', even after a wild space adventure) some age-reversing sweets, ''explicitly stating'' that each dose will make them 20 years younger. They decide to split ''all the pills they're offered'' between the three of them without even taking into account how many years they wanted (or ''could afford'') to regress, which results in two of the grandparents turning into babies and the third, the youngest, poofing out of existence forcing him and Willy to risk life and limb to save her from the Minus Land. At least the kids in the first book had the excuse of being, well, ''kids'' and having close to no parental control to keep them from getting into trouble. Here it's three adults, all of them around the age of eighty, ignoring Wonka, Grandpa Joe, Charlie, and their own children (Mr. and Mrs. Bucket), as well as their own common sense.
5* ''Literature/ACourtOfThornsAndRoses'':
6** The Archeron family are desperately poor and primarily rely on Feyre's hunting to get by. However, it's mentioned that Elain - who loves gardening - is able to maintain a small flower garden outside their cottage. Which begs the question: why didn't any of them think of trying to grow vegetables?
7** In the first book, Feyre's encounter with the shapeshifting puca in the manor garden, which she genuinely believes is her father. This is despite the fact that a) she knows some faeries can shapeshift and b) there's no logical explanation for her father getting there (he has a crippled leg and no wilderness survival skills - she even considers the possibility he came on a horse despite her family lacking the means to obtain horses - he has no idea where Feyre was taken in Prythian, and Feyre herself describes him as not the kind of man who would venture into faerie territory to save his captured daughter). In spite of all this, Feyre is immediately taken in by the illusion and isn't even a ''little'' suspicious.
8** At the end of ''A Court of Wings and Ruin'' Feyre and Rhys make a magical pact that if one of them dies so will the other. Besides the co-dependency issue, considering they're co-rulers of the Night Court it would leave the government leaderless and unstable, and possibly endanger the civilians. It only gets worse in ''A Court of Silver Flames'' after Feyre becomes pregnant, as if anything were to happen to one of them it would guarantee their child was orphaned, and it directly makes things even worse in the climax when Feyre nearly dies in childbirth. Several readers considered it stupid at best, selfish and irresponsible at worst.
9* In ''Literature/{{Masques}}'' a little girl goes outside, where she knows there are undead monsters, to fetch her ''doll''. Despite many people telling her that the undead don't eat dolls. Even for a five-year-old, that's implausibly stupid.
10* ''Talismans of Literature/{{Shannara}}'' does this to Wren, who just spent the last entire book learning how easy it is for trust to be betrayed, but who still falls for the trap of a character everyone (including her) suspected, just to get her kidnapped and in contact with the other good guys to tell them what she knows. When she gets back, nothing horrible seems to have happened to her army in her absence.
11* Grace in ''Literature/{{Vampirates}}'' takes forever to figure out that she's on a ship crewed by the titular creatures, despite knowing that they exist before they find her.
12* In the fourth ''Literature/MagicKingdomOfLandover'' novel, ''Literature/TheTangleBox'', Ben Holiday is informed by his long-time nemesis Nightshade that his newborn daughter will be the target of her next scam. In the fifth novel, ''Literature/WitchesBrew'', she goes through with this with a very obvious scam, and the one person who Ben refuses to believe could possibly be behind it... is Nightshade. He then spends the entire book stalwartly seeking the help of everybody in the world to identify who the real threat is and help him overcome it, only realizing that it's exactly who he should have known it was all along when he's told as much by his other long-time nemesis, Strabo.
13* ''Literature/TheDraka'' series of Alternate History novels, in which enemies of the Dominion outright ignore it until it's too late. Repeatedly. Knowing it's happened before. As one synopsis put it, the first 'alternate' in the setting's history must have been an 11th Commandment reading "Thou Shalt Not Attack the Dominion of Draka".
14** How much of Europe had Hitler taken before the Allies finally did something? All through history you will see people saying "Maybe if we just ignore it it will go away!"
15** This is actually directly addressed in the novels. The Europeans of the time viewed the Domination as a barbarian (nonwhite) nation with a thin veneer of civilized (white) rulers, certainly not a threat to the masters of the universe in Paris, Berlin, Rome, etc. And hey, who had they conquered up to that point? Some spear-chuckers in Africa, ragheads in the mideast, buncha Chinese out in the Orient, and the Turks? Nobody important or formidable, right? Racist and stupid, sure, but that's not even remotely unusual. Even in the real world, the Nazis and the Japanese military had convinced themselves that a 'mongrel' country like the USA could never be a real threat, despite the reality of the economic, industrial, and military situation.
16*** Interestingly enough, the Draka themselves begin to fall victim to this same attitude, referring to the Alliance as "feral humans" even before their genetic engineering programs really got going. [[spoiler: They still won the Final War, but it's clear they weren't expecting to take the casualties they did in the process.]]
17*** This [[http://web.archive.org/web/20120107141442/https://www.alternatehistory.com/gateway/analyses/Drakaproblems.html Alternate History page]] actually points out all the historical problems the canon timeline has and how illogical the entire idea is.
18*** For the Europeans to view the Draka as harmless requires them to ignore an empire which controls all of Africa and the Middle East, has the world's largest GDP, possesses the most technologically advanced military in the world (as demonstrated in multiple wars Europeans were involved in), and displays a tendency to kill hundreds of thousands of revolting slaves. Ignoring an entity like that when it's just across the Mediterranean is flat-out insane.
19* Herodotus tells of a king named Croesus who consults an oracle to determine whether or not he should attack an enemy's kingdom. The oracle says that if he attacks, "a great kingdom will be destroyed," at which point Croesus commits his army and ends up losing his capital city and being enslaved. He could've just asked which kingdom would be destroyed, but that's not nearly as fun, is it?
20** The Oracle was always intentionally vague, and there was even a quote upon the entrance to her temple saying, in effect, "Know thyself." In that respect Croesus held the idiot ball in that he overestimated his forces.
21** Also, asking just one question to the Oracle was a huge deal, as the questioner was expected to make an offering to the Oracle before asking. Croesus brought a HUGE load of loot all the way to Delphi, so asking "Which Empire?" would mean a trip back to Lydia, emptying more of his treasury, then another trip back to Delphi. Not the most economical way of divination, or maybe Croesus was just stingy.
22** To be fair, when the Persian King Cyrus allows him to send a message to the Oracle and he asks why he was told this, the Oracle tells him he should have asked what was meant and Croesus agrees.
23* In Literature/TheDresdenFiles, Our hero Harry learns that Nicodemus, an ancient evil warrior bound to the spirit of a FallenAngel, is immune to virtually all damage because of his ArtifactOfDoom, the noose Judas Iscariot hung himself with. Harry is the first person (as far as we know) in the roughly 2,000 years that Nicodemus has been active to realize that the noose (which must be worn around the neck to work) is also his AchillesHeel; it offers no protection from itself. After hearing on how an order of holy knights who wield a trio swords [[spoiler:made from the True Nails of the Cross, and are better known as Excalibur, Durendal, and Katsuragi]] have been fighting him ''for centuries'', and that they have precious little info on him as he routinely destroys their intel. Knowing all this, despite being close friends with one of them, and that he trusted said knight with his life on multiple occasions, ''Harry never mentions this weakness to anyone.''
24* In ''[[Literature/InheritanceCycle Eldest]]'', the Ra'zac show up in Carvahall looking for Roran. The townspeople recognize them as [[spoiler: the ones who tortured and killed Garrow,]] and tell them that Roran is out hunting and they don't know when he'll be back. Let's repeat that: the townspeople, in order to protect Roran, tell two [[spoiler: known arsonists/murderers]] that he's out and will be back later, apparently expecting them to turn around and go home.
25* ''Franchise/StarWarsLegends'':
26** ''Literature/TheThrawnTrilogy'': Despite all his military genius, Thrawn grabs hold of the idiot ball several times throughout the series which leads to his ultimate defeat.
27*** For one thing he lets Mara Jade live after he betrays her, which leads to her switching sides to aid the New Republic in taking out Mount Tantiss.
28*** He also grabs hold in dealing with the insane Jedi Master Joruus C'Baoth instead of eliminating him - which he had several chances to do.
29*** Thrawn also lets Niles Ferrier live even after one of Ferrier's colossal screw-ups results in the various smugglers uniting against the Empire. Thrawn tries to have Ferrier frame Talon Karrde as an Imperial agent, warning him that [[YouHaveFailedMe he better not fail]], but Ferrier screws that up as well. The only reason Thrawn doesn't kill Ferrier is that the other smugglers take care of Ferrier first.
30** ''Literature/NewJediOrder'':
31*** Mara Jade doesn't even find it a ''little'' suspicious that she can't sense Nom Anor with the Force. If she'd confronted him on it right off the bat, she'd have prevented about half the problems in the entire ''New Jedi Order'' series. [[FacePalm Way to go, Jade.]]
32*** After ten years of spying on them, Nom Anor doesn't even think it's a ''little'' dangerous to try and [[BerserkButton kill Luke's wife]].
33** ''Literature/XWingSeries'':
34*** Corran Horn is an ex-cop turned [[AcePilot fighter pilot]] for the Rebellion. He's given a cover identity and put on Coruscant (or [[InsistentTerminology Imperial Center]], as it's known), the capital city-world of the Empire, to gather information as part of an operation to take the planet. But one day, after one of his companions tries to have sex with him and he refuses, he decides to go walking while [[ContemplateOurNavels ruminating on his past]], and pays no attention to where he is going. At all. He finds himself at a WretchedHive and as it turns out the whole thing acts as a LuckBasedSearchTechnique, but really, wandering an enemy-held world and heading into the depths of its seedy underbelly while not paying attention to where he's going? The Force looks after fools.
35*** Corran is mostly distracted by Tycho being on the planet, and it's dumb luck on a planet of billions (maybe trillions) that the one criminal with a grudge finds him. The real ball comes from Corran, whose 'cop instinct' just won't let him stop believing Tycho was a traitor despite the fact if he was brainwashed Isard could have used him at any time in the countless missions to take Imperial Center.
36*** In ''Starfighters of Adumar'', Wedge Antilles's decision to confront [[spoiler:Tomer Darpen]] during a diplomatic event, letting the latter know ''exactly'' how much Wedge knows about their plans, is almost certainly a factor in the latter's attempt [[spoiler:to get Wedge killed in combat after Wedge declines to participate in Cartann's coming war of conquest]]. It's possible that person would have tried it even if Wedge hadn't said anything, but Wedge ''really'' should have known better than to let a person know [[HeKnowsTooMuch how much he's figured out]] while said person is still in a position to do something about it. Especially since in this case, [[spoiler:Darpen is supposed to be their ''ally'']].
37** In ''Literature/StarWarsKenobi'', [[spoiler:Orrin Gault]] is deliberately antagonistic to Binneed and his lackeys when they have him under guard, ignoring Binneed's attempts to be FauxAffablyEvil and insulting them until they finally decide to torture him for a bit.
38** ''Literature/LegacyOfTheForce'':
39*** Han is insistent on supporting Corellia in the insurrection, even though he knows full well what its leader, his cousin, [[JerkAss is like]].
40*** Mara Jade doesn't realize it's a bad idea to go off alone to confront a Sith. She thought it was Lumiya, but still, she might not have been [[spoiler:caught and killed by her Sith nephew]] if she'd have taken some backup with her.
41* ''Literature/{{Sylvester and the Magic Pebble}}'': Sylvester [[BeCarefulWhatYouWishFor wishing he was a rock]]. On the other hand, he ''was'' about to be eaten by a lion and just blurted out the first thing that came to mind.
42* Charles Todd's ''A False Mirror'' starts off with several characters playing "catch the Idiot Ball":
43** Stephen Mallory, confronted by local detective Bennett about the mysterious disappearance of Matthew Hamilton, husband of Mallory's former girlfriend Felicity, immediately charges off to see Felicity. This despite the fact that Mallory is automatically the ''prime suspect'', since he is still obviously obsessed with Felicity.
44** In the course of evading Bennett, Mallory [[spoiler: runs over Bennett's foot with his car.]] This does not make Mallory more popular with the local constabulary.
45** When the police catch up with Mallory at the Hamiltons' house, Felicity has the brilliant idea of [[spoiler: pretending that Mallory is holding her and her maid, Nan, hostage. At gunpoint.]] It belatedly occurs to her that this is the epitome of an Idiot Ball maneuver.
46** To make matters worse, Nan tells two different people, including Inspector Rutledge, that [[spoiler: Felicity set up the mock hostage situation.]] Nobody feels obligated to inquire further.
47* In "The Marching Morons" by Creator/CyrilMKornbluth, the population of Earth has literally "Bred for stupidity" by smart people choosing to have fewer children while idiots continue to breed indiscriminately. They have to resort to reviving a HumanPopsicle to solve the problem.
48* Victor Frankenstein, in Mary Shelley's original ''Literature/{{Frankenstein}}'', is warned that the monster will visit him on his wedding night. So he leaves his new bride alone while he goes outside to reconnoiter the area. And he's surprised when the monster [[spoiler: breaks into the bedroom and kills his wife]]? Not only that, Frankenstein could have avoided the whole problem if, instead of "aborting" the creation of a bride for the monster because he was worried about hordes of the creatures overrunning the world, he'd simply made her infertile. (As for the last, though, it has been argued that perhaps it wasn't obvious to the writer -- back in those days, their science being whatever it was -- that this should have ''been'' a possibility for someone who could create an approximation of a human being out of nothing much.) To be fair, the creature often watched Frankenstein work, so even rendering the bride infertile wouldn't have stopped the creature from making more like itself. No, Frankenstein's turn with the idiot ball comes when he doesn't talk to his creation, pointing out that while the creature had promised to go away and live quietly with its new bride, neither of them could assume that the bride would agree to the same arrangement. No, he just panics and destroys the bride while the creature watches, because PoorCommunicationKills.
49* Huge example in the ''Literature/MortalEngines'' series: The protagonist is just about to escape from a city under siege using an air balloon, which is about to fly to the place his love interest is staying. One idiot ball later, he jumps out of the balloon, while it's taking off, while everyone's shouting at him to stay in the basket, while the city's being destroyed, and runs off to fetch a letter from said love interest. A letter he's already read. Needless to say, the balloon's gone when he gets back.
50** In case you are referring to [[spoiler: Theo Ngoni]] in the final book, then it's more like this: A major character (not the protagonist) is about to escape from a military base which is attacked by traction cities. And it's about to be overrun. He is just about to board an airship along with his companions (which will take them not to his love interest, but simply to a safer place) when he remembers the letter and runs back to the base. His friends conclude that they are forced to leave him behind, the base being bombed and all. After finding the letter from his love interest, and also a photo of her, he runs back again, but [[spoiler: is hit by a grenade from the attacking cities. [[NoOneCouldSurviveThat He survives.]] ]] Still a strong case of IdiotBall.
51* In ''Literature/AConnecticutYankeeInKingArthursCourt'', said King and Yankee decide to do some legwork among the peasants. What gives away their disguises? The King babbling on about how turnips grow on trees and apples below ground.
52** Justified, as the King is shown to have no knowledge of anything outside his castle. In fact, the whole point of this trip is to educate the king.
53* Every named character in ''Literature/TheWheelOfTime''. Notable incidents:
54** Pedron Niall employing Padan Fain as an advisor.
55** Everything Eladia has done from book 5 onward, assuming she was actually smarter than that to begin with. She only got worse after being [[TheCorruption corrupted]].
56** Moiraine insisting on upholding the tradition of Aes Sedai superiority by withholding information (even from the ''[[TheChosenOne ta'veren]]'').
57*** Nearly all the characters seem to have this version of the Idiot Ball. Nobody ever tells anybody anything. It's justified occasionally, but you'd think there would be a little more truthfulness between the cadre of friends meant to save the world.
58** Suian Sanche sending untrained girls after a group of thirteen Black sisters. She didn't trust anyone else, but that's no excuse.
59*** Said untrained girls manage to carry the ball themselves. When Mat breaks into possibly the most heavily guarded fortress in the world to save them and rather reasonably objects to them assaulting a helpless woman they decide to handle this complaint by ''tossing him around with their powers''. Yes, the woman was blocking them from using their powers and they needed to punch her to stop that but they never bothered to explain that, simply deciding to threaten Mat. It isn't until many books later (with the prodding of one of the few intelligent characters) that they actually give a half-hearted thanks.
60** Even worse, they got captured in the first place by walking straight into an obvious trap, by claiming that "A trap isn't a trap if you know it's there". Despite knowing it was there, they at no point acted differently than they would have otherwise.
61* A moment in the first ''Literature/TheKingdomKeepers'' book. Finn and Philby, looking for clues, search ''[[Ride/DisneyThemeParks Splash Mountain]]''. Since the ride inactive, they don't take a car, facing HazardousWater. Philby waits until they are well into the ride before telling Finn that they can't get out on the sides without setting off alarms. Meaning they have no plans to survive a five-story drop.
62* Cergorn in the second ''Literature/{{Shadowleague}}'' book is definitely holding this when he [[CardboardPrison imprisons Veldan and Kazairl in their home, sets their good friends to guard them]] and expects them to stay put.
63* ''Franchise/DoctorWhoExpandedUniverse''
64** The ''Literature/EighthDoctorAdventures'' give [[Series/DoctorWho the Doctor]] a WorthyOpponent who is about twice his size and apparently has twice his brainpower, having to explain to the Doctor the Franchise/{{Whoniverse}}'s second-most-obvious explanation for someone becoming a bit slimmer than they were previously[[note]]Turns out the most obvious explanation, diet and exercise, doesn't apply, but probably continues to plague the Doctor with confusion to this day[[/note]]:
65--->"Your suit [[AttentionDeficitOohShiny distracted me]] for a while," [the Doctor] added. "I couldn't understand how you managed to squeeze your [[IShallTauntYou rather ample form]] inside it."\
66Sabbath was amused rather than angered by the comment. "Really, Doctor?" [[FascinatingEyebrow He raised an eyebrow.]] "I didn’t expect you to have any trouble understanding how something can be [[BiggerOnTheInside bigger inside than it appears from without]]."
67** An Eleventh Doctor book called "Hunter's Moon" has Rory, probably the most level-headed one between him, Eleven and Amy, gambling away the TARDIS and getting himself kidnapped to a place where humans are hunted.
68** In the Quick Reads novel ''Code of the Krillitanes'', the Tenth Doctor discovers Earth has been affected by a new product called Brainy Crisps that turn kids into geniuses for unknown ends. He has to take a packet to the TARDIS and run tests on it before he even ''begins'' to connect this with the alien race that was last seen boosting children's intelligence with fried potato products.
69* ''Literature/DigitalFortress'', where a half dozen computer scientists and mathematicians spend six pages scratching their heads before realizing that the word [[spoiler:PRIME]] in a password could refer to [[spoiler:Prime Numbers instead of Prime Ribs]].
70* Deliberately invoked and PlayedForLaughs: In ''Literature/AtlantaNights'' Bruce Lucent spends a chapter trying to find out if his parents were his bio-parents when it turns out he's [[spoiler: black]] when his parents aren't. Nobody else noticed either.
71* In ''The Temporal Void'', Troblum has software in his implants that can read other people's facial expressions and body language, since he's [[IDoNotSpeakNonverbal not so good at]] doing it himself. When he notices the people around him behaving oddly in one scene, instead of activating this software (which would be completely inconspicuous and take a split-second), he rationalizes that it's probably nothing [[spoiler:and blunders into a trap. Once the Big Bad springs her trap, ''then'' he activates the software and sees that, yep, everyone else is scared out of their minds because the Big Bad has been holding them at gunpoint and lying in wait for him.]]
72* Although she's by no means presented as being particularly intelligent any other time, Anne Steele (Lucy's sister) picks this up big time in Creator/JaneAusten's ''Literature/SenseAndSensibility''. She is well aware that Lucy's engagement to Edward Ferrars is a closely guarded secret. But as they're staying in the home of Edward's sister, she decides that she should go ahead and tell her hostess the truth because surely that will work out...
73* In Pseudonymous Bosch's ''Literature/SecretSeries'', {{Cass|andraTruth}} loudly remarks that a gourmet chef's cooking might be improved with the MacGuffin of the book. The only people who [[HeKnowsTooMuch know about its existence]] outside of her friends are part of [[AncientConspiracy the Midnight Sun]], and Cass knows firsthand that they're willing to abduct and murder people who expose their plans. When [[EvilChef Senor Hugo]] asks Cass if she knows exactly what the [[MacGuffin Tuning Fork]] ''is'', she tells him, which results in Hugo (an agent of the Midnight Sun) [[HostageForMacGuffin abducting her mother]]. Although this isn't the only time Cass slips up; in the first book, she decides to investigate the Midnight Sun's spa alone by posing as a celebrity, not stopping to think that they might have caller ID, and falls into a trap. Later, she and another character eat pieces of chocolate [[SchmuckBanquet laid out in the villain's hideout]] (especially glaring since they know that enchanted chocolate is Hugo's M.O.), getting them captured. Then Cass eats ANOTHER piece at the end of the book, which puts her into a coma.
74* The [[LizardFolk Race]] does this a lot in Creator/HarryTurtledove's ''Literature/WorldWar'' series. To be fair, though, human behavior is as alien to them as they are to us. However, they will mindlessly believe anything their superiors tell them, even when there is evidence to the contrary. Case in point, the Race medics have come up with a TruthSerum that works on humans and have claimed that it is 100% effective. It is then tested by a Race commander on a human, who is obviously lying, and the serum fails. While the commander is still suspicious of the man, he concludes that he must be telling the truth based solely on what he has been told by his superiors.
75* Actually justified (at least in one case) in Creator/DavidEddings' ''Literature/TheElenium''. The [[GodOfEvil Dark God]] Azash has no grasp of subtlety, and this quality creeps into those who serve him. Thus, formerly renowned {{Manipulative Bastard}}s are found concocting infantile plots which are undone with incredible ease. They seem to get over this, however, and serve a greater threat toward the end of the series.
76* Semi-example in the Dungeons and Dragons fourth edition novel The Mark of Nerath. A death knight gets his hands on a vial of mysterious liquid which compels him to do things that are... not in his best interest.
77* As Creator/NoahAntwiler points out, a great deal of agony and stress in ''Literature/{{Twilight}}'' could have been avoided if Edward just ''let Bella be on top when they have sex'', avoiding the problem of him being too strong and breaking her. Given his vampiric super-hearing, he should have known something unusual was going on inside Bella's body ''before'' she revealed to him [[spoiler:that she was pregnant]].
78** In spite of Carlisle's doctoral degrees, when Bella was starving to death, it took an unschooled haughty teenage boy to tell him that [[spoiler:a half-vampire fetus ''needs blood''.]]
79*** This is a ''special'' piece of idiocy in that a fetus gets their nutrition from their mother through the placenta, which transfers oxygen and nutrients from the mother's blood to the placenta where the fetus can use it, and, as the fetus develops more, through the umbilical cord. Two arteries in the umbilical cord [[http://www.livestrong.com/article/230923-how-does-nutrition-get-from-the-placenta-to-the-fetus/ carry blood pumped from the left ventricle of the fetal heart to the placenta to receive oxygen and nutrients from the mother. The vein returns the oxygenated blood from the placenta back to the right atrium of the fetal heart.]] In other words, from a biological standpoint, it doesn't ''matter'' if Bella consumes cheeseburgers, a vegetarian casserole, or a pint of O-negative--because all of the nutrition [[spoiler: the half-vampire fetus]] is receiving comes from the same source--Bella's own blood.
80** As well as the one Rosalie took on when she took over responsibility for the newborn baby and immediately let her guard down, despite knowing full well that there was a vampire-slaying werewolf in the house.
81* Literature/SisterhoodSeries by Creator/FernMichaels: In the book ''Lethal Justice'', Charles Martin uses powerful connections to force reporters Maggie Spritzer and Ted Robinson to relocate to New York and stay there, where they can be constantly watched. That's fine. What's not fine is how the next book ''Free Fall'' has Maggie and Ted move back to Washington, D.C., without Charles and the men with presidential gold shields being aware of this development at all! Maybe Charles and those men were not as smart as they believed they were!
82* ''Literature/SeptimusHeap'':
83** A lot of trouble in ''Magyk'' could have been avoided if Queen Cerys hadn't taken the Custodians as her bodyguards.
84** Without Silas Heap opening the Sealed room in the Palace and unwittingly releasing Queen Etheldredda in the process in ''Physik'', the whole plot wouldn't have occurred.
85* In ''Literature/WorldWarZ'', a good deal of the entire world (except Israel) seems to have become complete idiots for large portions of the book, by burying their heads in the sand and trying to ignore/suppress the zombie problem until it was too late. Most notably the Battle of Yonkers. The galling part is that many of the same people responsible for that had a SmartBall before that and later on. The US military suddenly became absolutely incompetent for that one sequence to happen.
86* The characters in ''{{Literature/Redshirts}}'' are well aware of the Idiot Ball, as the Narrative passes it from character to character for dramatic effect. Lampshaded in that most of the characters realize their actions are completely stupid, if not at the time, then after, yet are unable to help themselves.
87* ''[[Literature/TheHungerGames The Hunger Games]]''
88** Katniss doesn't realize [[spoiler: Peeta genuinely had a crush on her]] and Peeta assumed [[spoiler: Katniss's reciprocation was real]]. Katniss is simply terrible at reading people and when Peeta declares his love for her on national television, most people would have used it to their advantage to get more sponsors.
89** Plutarch Heavensbee goes out of his way to show Katniss his watch [[spoiler: which is a clue for surviving the arena]] and it doesn't occur to Katniss that the [[spoiler: Mockingjay hologram in his watch hints that he is an ally.]] In fact, even after Katniss does realize it [[spoiler:was a clue]] later on, it never once dawns on her that was the point - [[spoiler:even after she hears Plutarch with Haymitch and Finnick on the airship that saves her. It takes Haymitch restraining her, then sitting her down to explain for her to get it.]]
90* ''TabletopGame/{{Warhammer 40000}}'':
91** In the Literature/HorusHeresy books, the Emperor of Mankind plays the Idiot Ball big time causing his own near death and the downfall of his empire through mistake, misjudgment and a total failure to comprehend basic human behavior much less the emotional needs of his 'sons'.
92** 40K is an idiot ''setting''. Pretty much every major event is driven by people, often on both sides, making terrible, short-sighted decisions that blow up in their faces.
93* ''Literature/TheMortalInstruments'':
94** At the end of ''City Of Glass'', Clary decides to [[spoiler:wish Jace back to life. Which is great except she seems to have forgotten about all the other shadowhunters that died.]] Real considerate there, Clary. Though considering what happens [[spoiler: it causes Jonathan to come back to life and create an anti-nephilium group]], this might not be a bad thing.\
95\
96She usually grabs the IdiotBall and runs with it whenever Jace is involved, [[spoiler:like when possessed!Jace is able to trick her into mind-control just by batting his eyelashes at her and playing on her hormones]].
97** Jace grabs it with a bloody deathgrip when he refuses to tell anyone about the possible [[spoiler:prophetic dreams he's having about murdering Clary until it's almost too late, nearly starves himself to death, doesn't sleep... oh, and ends up getting himself possessed by Sebastian. What an IDIOT.]]
98
99** Simon holds this ball himself a few times too. In ''City of Fallen Angels'', While it's not entirely his fault that he ends up in an unhappy dual relationship with Isabelle and Maia, he should've chosen Isabelle over Maia, since he really liked her over Maia, but it takes Jordan's meddling for the two to know about each other. (not that Jordan is getting off easy too, but he'll be touched on later)

101** Earlier in the novel, Simon tells Luke that he doesn't constantly acknowledge himself as a vampire and why he doesn't use his Mark of Cain power when he needs to, believing that if he ignores it, it'll go away...only for Luke to say how idiotic this is, as his power is so unique and powerful that it'll draw the attention of those who want to use it, and Simon, for their own purposes; ignoring it is much more idiotic than Simon thinks it is. Also, earlier in the novel, Simon throws out much of his blood supply after his mom learns about him as a vampire and he's forced to leave home, which causes him to run low and plays a part in him biting Maureen.

103** Isabelle hold this ball too with a tight fisted grip. Following the end of Clary's faux relationship with Simon in ''City of Ashes'' she believes Simon to be a bad guy (She likes bad guys) and this plays a part in her getting Simon into a 'fake' relationship with her in ''City of Fallen Angels''. After she tells Clary about the fallout of the revelation of her and Maia both dating Simon, Clary berates her for thinking her plan could work without hurting Simon and herself, which makes Isabelle feel like an idiot and realize that she truly likes Simon and practically threw away her chance to be with him. (Though this is only temporary, as they become a permanent couple later on in the series) She feels like more of an idiot later on when Simon reveals what truly happened when Clary got with him and how they weren't truly a couple, meaning he wasn't a bad guy at all.
104** Jordan holds this ball as well even before the series begun. After becoming a werewolf, he lost control of himself and bit Maia, which made her turn, and in her eyes, was the moment he ruined her life. In ''City of Fallen Angels'', Simon is angered to learn that he mainly got close to Simon and used his connections in the Praetor Lupus to get himself assigned to Simon to get close to Maia and try to win her back. Although he does win her back in the back, it was still idiotic of him to use Simon like he did, though he tells Simon he didn't mean to abuse their friendship like he did and truly calls him a friend.
105** Clary's mother, Jocelyn, often holds this ball with almost the same grip as Clary. Her first, and arguably most boneheaded move, was gaslighting Clary into believing she was a mundane, all because how ashamed she was of marrying Valentine and giving birth to Clary's evil older brother, Jonathan (Sebastian). Even worse, her efforts to hide crucial details about Clary's life from her not only amplify Clary's curiosity and determination to find out for herself, but it also makes Clary lose faith and trust in her. In "City of Lost Souls" Isabelle tells Jocelyn all this to her face in a Reason you Suck speech. Also, her only real reason for disliking Jace is the fact that Valentine briefly raised him when he was an infant before dumping him on the steps of the New York Institute. In short, Jocelyn might be trying to make amends for being Valentine's wife, but in this case, Mother doesn't always know best.
106* ''Creator/SimonaAhrnstedt'' gives us a really painful example of this in her debut novel, ''Literature/{{Overenskommelser}}''. It's the story about young Beatrice, who's bullied and pressured by her abusive and tyrannical uncle into an engagement with a man. A man who's not only like forty years older than her, but he also treats women like they're dirt under his shoes. So what does she do? Of course, she tells nobody the truth about why she agreed to marry this man (he would get her beautiful but weak cousin instead, if she didn't sacrifice herself). To be fair, she really is in a crappy situation, but still, yikes... And unfortunately, her love interest Seth is no better. Since he thinks that she willingly rejected him to marry an old disgusting aristocrat, stupid pride keeps him from admitting that he loves her. Several misunderstandings between them (sigh...) leads to much misery for them both (including that Beatrice gets [[spoiler: brutally raped and battered on her wedding night]]).
107** Not to mention that while Beatrice is a very intelligent young woman, when it comes to academical and intellectual pursuits, she can still make some very [[DitzyGenius dumb decisions]].
108* Beka's journaling in ''Literature/BekaCooper'' is explicitly a memory aid, to the point where her watch commander orders her to start doing it again after her reports get sloppy. However, there are a few points where Beka struggles to remember some key detail crucial to the case. Does she go back over her old journal entries where she has already written about that precise thing? No, she just tries to remember it on her own. Okay.
109* The comedic fantasy ''[[Literature/ZeusIsDead Zeus Is Dead: A Monstrously Inconvenient Adventure]]'', in which the Greek gods (including the nine Muses) return to the modern world, has an ''actual'' Idiot Ball. It's usually kept safely in conceptual form in the Muses's Hall of Creative Abstract Concepts on Olympus. [[spoiler: Thalia has the other muses coalesce it into physical form for her as part of a plan to free Leif and Tracy from Dionysus's casino. Then she loses track of it.]] Problems occur.
110-->'''Dionysus:''' It's a little golden ball!
111* Several of the Bloody Jack books require Jacky to hold the Idiot ball. Especially in Boston Jacky where she suddenly can't spot the kind of trouble she's been dealing with repeatedly in the past.
112* ''Literature/TheAdventuresOfArchieReynolds'' works entirely on this. It gets passed from character to character.
113** Why do a bunch of jewel thieves decide to hide the tunnel they'd dug underneath a very obvious stone slate in the backyard of an abandoned house? They lock their box of jewels with a combination lock, then put a piece of paper on the back of the box telling where to find the combination. Why not just memorize it or write it somewhere people wouldn't see?
114** Our heroes, meanwhile, decide to take an inflatable raft across a river on a day that's heavily overcast, and are shocked when it starts raining heavily.
115** Archie hears "mmph mmmph" coming from a crate on the day that he'd just heard his neighbor got kidnapped, but takes 3 pages to realize what's going on.
116** For that matter, the kidnap victim was kidnapped by the jewel thieves and put in the crate because they noticed that someone had stolen their jewels. Why put the kidnap victim in the same place when you just noticed that people have discovered your hideout? Why not hide her somewhere else? The entire story is full of stuff like this.
117* In ''Literature/TheChemicalGardenTrilogy'', despite the looming threat of humanity's extinction, Gathers run around killing hundreds of girls for not being pretty enough for marriage or prostitution.
118* The villains in ''Literature/SchoolsOutForever''. [[spoiler:They replace Max with a clone and have her infiltrate the flock. Apparently they forgot that Angel (whom they gave the power to) can read minds]].
119* Notably [[AvertedTrope Averted]] midway through Geoph Essex's ''Lovely Assistant'': after yet ''another'' weird moment with some [[StepfordSmiler very weird]] [[TheBeautifulElite acquaintances]], protagonist Jenny suddenly chucks the IdiotBall so hard you can almost hear the RecordNeedleScratch.
120--> '''Jenny:''' Okay, you know what? I'm not going to be stupid anymore. There's enough crazy shit going on in our lives that I should really stop ignoring something just because it's a 'coincidence.'
121* In the ''Literature/NowhereIslandUniversity'', the titular university's only frat has seemingly grabbed this before the story even begins. For instance, despite having somewhere between a hundred and fifty and two hundred people, most of them armed, they somehow manage to lose to eight people who started off the fight without weapons.
122* ''Literature/TheMazeRunner'': According to ''The Death Cure'', the Coalition government that [[spoiler:released the Flare didn't seem to realize that sometimes viruses ''mutate.'' Weren't these supposed to be the world's top scientists and biologists? Did they just forget that this happens? '''Especially''' considering radiation is a prime source of viral mutation, such as the intense solar radiation that the Earth was being subjected to? What did they think was going to happen?]]
123* Attorney Benjamin Arcinas carries this for much of ''Literature/SmallerAndSmallerCircles'', particularly during the early half when he tries to shoo off the priests' attempts to help and ignores their advice when he takes charge of the investigation.
124* Lampshaded and then immediately double-subverted in the ''Literature/TheLaundryFiles''-novel ''The Jennifer Morgue''. Bob Howard, whom the villain knows is a world-class computer security guy, is captured by the villains and placed in a room on their flagship... that has a PC Entertainment Center. Bob immediately namedrops the trope, since one of those is more than powerful enough to do serious damage to a computer network in the hands of a sufficiently motivated hacker. However, when Bob examines the machine, he realizes the villains were smarter than he gave them credit for; they've removed all input devices except the remote control, locked all functions except the media players for everyone without an admin account, and very purposefully plugged up the Ethernet port. However, since Bob has, secreted about his person, a collapsible keyboard, a USB-stick containing about a quarter of a million worth of hacking tools and a vial of the villain's magical mascara, which connects what it is applied to to the villain's surveillance network (originally developed to let the villain use peoples' eyes as cameras, good for corporate espionage and security), their efforts were moot anyway.
125* Risevim in ''Literature/HighSchoolDXD'' is completely immune to Sacred Gears. After this is revealed for the first time, you'd expect the people fighting him to either use non-Sacred Gear-based attacks or let people who don't have Sacred Gears handle him (the second option is even lampshaded by Sirzechs' peerage, which doesn't have any Sacred Gear possessors in it for this reason). However, Issei and Vali (both Sacred Gear possessors) are the ones who mainly fight him, and they charge him head-on! Particularly egregious in Vali's case, as he's also a powerful magician.
126* ''Literature/VillainsDontDateHeroes'': Night Terror, who knows [[spoiler:that mind control exists, repeatedly sees Selena demonstrating strange behavior when talking to her boyfriend over the phone, and yet never considers that she might be mind controlled]]. Night Terror implies near the end that [[spoiler:she had assumed that Fialux was immune to mind control just like everything else, so the possibility never crossed her mind]].
127* ''The Clifton Chronicles: Mightier than the Sword'': Harry Clifton is a smart and successful detective novel writer. He very publicly wants to free a man who's a political prisoner in the USSR because he wrote a memoir of Stalin, and knows the KGB is monitoring him and trying to sabotage him, at least while he's in Russia. Eventually, the prisoner's wife tells him where the one surviving copy is. [[spoiler:So he goes to Russia, goes ''directly to the book's location'', takes it, and heads directly back to the airport. The Russians stop him at Customs. And point out how incredibly blatant he was, from the second he talked to the wife.]]
128* ''Literature/UnderHeaven'': As later in-universe historians points out, first minister Wen Zhou ordering the army of Xu Bihai to march out of the safety of the impregnable Teng Pass fortresses to engage Roshan's forces (which, as has been pointed out earlier by the general, was already crumbling with the strain of maintaining the siege) in open battle was probably an [[{{Understatement}} unwise]] thing to do. Funnily enough, Roshan's forces are so blindsided by the stupidity of Xu's attack that Xu almost managed to win the battle from sheer RefugeInAudacity -- unfortunately, that was not enough, the battle was lost and the capital was lost to the rebels by the end of the week. The incident was based on the real life Battle of Tongguan.
129** Another in-universe example pointed out directly by Shinzu: Wen Zhou sending An Li/Roshan away from the capital in the first place, when his rebellious instincts could have been dampened by [[BreadAndCircuses keeping him at court, lavishing honors on him]], and waiting for him to die from a galloping case of diabetes.
130* ''Literature/TheStand'':
131** Stu and Frankie get it at the end. Stu gets uneasy around the growing Free Zone population and wants to find a more private place to live. But instead of just finding a quiet place somewhere near Boulder where they’d still be close enough to get medical help if needed, they set out to go across the country. Frankie’s pregnant again and they think they can find drugs and learn from books. Medicine doesn’t work that way, guys, seriously. Drugs expire fast and if there are birth complications or someone has a heart attack or gets an infection, they’ll be in big trouble.
132** Stupidity is a common reason for deaths after the plague because there were no emergency services left to deal with people’s stupid actions. Like the guy who injected himself with a heroin overdose. And the lady who didn’t prop her walk in freezer open and got trapped.
133* Hank Rearden in ''Literature/AtlasShrugged'' has been explicitly told and shown by Fransisco D'Anconia that the latter is sabotaging his own company to screw with all the politicians and businessmen that are hoping to profit from him. Fransisco has been friendly to Hank, while being insulting to just about everyone else, but says he doesn't want to do business with him. Hank then decides it's a good idea to make a crucial order with Fransisco's company under a fake name. He somehow manages to be shocked and angry when the delivery ends up sabotaged.
