* Several of the "heroes" in ''Literature/ASongOfIceAndFire''. Unfortunately, they live in a CrapsackWorld, so [[AnyoneCanDie they tend to die a lot]].
** This is usually a matter of HonorBeforeReason.
** Four books and several thousand pages in, and most of the surviving "good guys" seem to be getting better: Jon and Dany have both gained a measure of pragmatism after attaining positions of power; Arya has had to live entirely by her wits since [[spoiler:her father's death]]; and former WideEyedIdealist Sansa is even taking lessons in {{Magnificent Bastard}}ry from none other than [[TheChessmaster Littlefinger]] himself. In many ways, this can be seen as the younger generation overcoming the flaws that killed their parents and older siblings.
* The {{Dragaera}}n House of the Dzur, a.k.a. the House of Heroes. Not all Dzurlords fit the stereotype (i.e. near-suicidal bravery and a shortage of little grey cells), but many seem to.
* Mentioned in an author's note that Eragon of the Literature/InheritanceCycle is not too bright. Obvious from reading the text.
* ''Literature/HarryPotter''. He may not be ditzy or absent-minded per se, but he suffers from a terminal lack of self-preservation and trust into his peers, especially adults, as well as total and persistent inability to foresee the consequences of his actions. At least OnceAnEpisode he rushes heads forward into a situation he has no feasible way of mastering, usually without any planning or preparation. Only [[TheSpock Hermione]], [[DeusExMachina Dumbledore]], and the fact that all the villains [[IdiotBall suddenly become stupid]] at the crucial moments keep him from killing himself.
* ''Literature/TwentyThousandLeaguesUnderTheSea'': Verne’s writing constantly informs us (and Counseil and Aronnax repeatedly lampshade) that Ned Land is a HotBlooded, GreatWhiteHunter, BigEater RealMenEatMeat BookDumb BadAss [[ArsonMurderAndJaywalking who is from ]] [[CanadaEh Canada]]. FridgeBrilliance when you realize that Land ''needs to be'' an Idiot Hero: [[spoiler: Ned Land's personality permits him being the OnlySaneMan capable of resisting Captain Nemo’s charisma]].
* HarryHarrison's ''BillTheGalacticHero'' books involve the titular character being a dumb farmboy on a backwater planet being tricked into enlisting into the fleet. He makes one stupid decision after another, mostly related to drinking, women, and money. In one of the novels it's revealed that his stupidity is directly caused by excessive drinking. When he's put on a prison ship for a few years without a drop of alcohol, his IQ jumps to genius-level, and he figures out several important things, such as the meaning of life (which, in LaymansTerms, can be phrased as "Life = Crap"). Then, at the end of the novel, he shares a toast with his friends, and promptly forgets everything he has learned. Most other characters aren't much smarter, at least the human ones. TheEmperor is an inbred who can barely string two sentences together, and the admiral in charge of the fleet in the first book is a ''baby'' in diapers. Is it any wonder TheEmpire is losing the war with the [[LizardFolk Chingers]] (which it started in the first place)?
* Michael in the ''KnightAndRogueSeries''. Luckily, his squire Fisk was blessed with all the common sense Michael lacks.
* One of the running questions of the ''HalfPrince'' novels is whether the protagonist is one of these. Her narration always has ''some'' explanation for whatever stupid thing she's just done, but other characters tend to think she gets by on luck, attractiveness, and/or being so stupid that [[AchievementsInIgnorance she doesn't "know" she can't do something everyone else falsely thinks nobody can do]].
* Deconstructed in ''Literature/WarriorCats'' with Foxleap, whose stupidity inadvertently causes the death of another cat and causes him to start feeling immense pain.
* Matteo in ''Literature/SomeoneElsesWar'' is an interesting example of one of these. He is actually rather tactical and ''tries'' to plan ahead, but when the situation calls for a snap decision, [[IdiotBall he always makes a stupid one]]. (Why yes, Matteo, jumping on the tail of a tank after you've thrown a grenade at it ''will'' give you [[BodyHorror first degree burns]].)
* Percy Jackson in ''Literature/PercyJacksonAndTheOlympians'' is, not, er, the sharpest blade on the weapon rack, and a whole list of his idiotic moments could get its own page. One such example is that, in his ''first book'', no less, he tried to get his friends to take a photo with [[spoiler: Medusa.]]
