Twilight Sparkle: How did you find that?
Pinkie Pie: It was under EEEEE!
This would seem to derive from Cervantes' Don Quixote, where the archetypically "simple" Sancho Panza occasionally produces statements of great wisdom (although in that case the main character, Don Quixote, often fails to notice or credit that wisdom).
See also: Achievements in Ignorance, Too Dumb to Fool, Whoopi Epiphany Speech, Infallible Babble, Hanlon's Razor. Contrast Ditzy Genius, which is in many ways the diametric opposite of this trope, and Seemingly Profound Fool, in which other characters erroneously read wisdom into the genuinely banal observations of a bona fide fool.
- Misaki Yata from K has moments of this. Particularly, late in season 2, to Saruhiko: "You're not a traitor! If you'd go this far for him, the Blue King was your King all along!" Saruhiko lampshades this when he's thinking about it just after Misaki leaves.
- Nijimura Okuyasu from JoJo's Bizarre Adventure: Diamond is Unbreakable is often like this. For example, he convinces himself that Yoshihiro Kira, the ghost Stand user, doesn't actually need to breathe because if he did, in his words, "all the dead people would suck up the air and we'd all suffocate". Well, he's technically correct, right?
- Not a perfect example, but the Rhino in Spider-Man does this occasionally, much to the surprise of other villains.
- Obelix in Asterix. He's a bit socially awkward and only seems to have a vague idea what's going on most of the time, but because of this is able to see contradictions and strangeness in cultural behavior everyone else sees as being normal. His Catch-Phrase — "these Romans are crazy" — represents this about half of the time (the other half of the time, he is just mistaken about what the Romans are thinking).
- In Twisted Toyfare Theatre, Mego Spider-Man seems to totally lack his signature super-powers, but also happens to be the only person in Megoville apart from maybe Dr. Doom who has a single lick of common sense.
- In Frozen, the child-like living snowman Olaf is surprisingly insightful about the nature of love, despite only having been "alive" for a day or two, and gives Anna some advice on the subject.
Anna: I don't even know what love is...
Olaf: That's okay, I do. Love is... putting someone else's needs before yours, like, you know, how Kristoff brought you back here to Hans and left you forever.
Anna: Kristoff... loves me?
Olaf: Wow, you really don't know anything about love, do you?
- Cyril The Zombie proved himself to be one in Wreck-It Ralph.
Cyril: Ralph, Zangief saying, labels not make you happy. Good! Bad! Errgh! You must love you.
- The Scarecrow from The Wonderful Wizard of Oz, both the book and movie. He wishes for a brain, yet neither he nor anyone else he's traveling with notices the discrepancy.
- Older Than Steam: The Beast in the original literary fairy tale "Beauty and the Beast" is described as speaking with much common sense, but "never what the world calls wit." (And yes, at the end of the story, the Prince is transformed to be witty and eloquent in addition to handsome.)
- In Alexander Pope's The Rape of the Lock, right before the incredibly epic battle over an involuntary haircut, Clarissa, probably a lower-status lady than most of the players, rebukes everyone on how it's silly to waste energy over such a trivial matter, and how good humor is a better tool than beauty or tantrums to weather the storms of life. Of course, no one listens to her.
- Witches sometimes provide this, since they're often quite intelligent about human nature while not being very well-educated. Sometimes, they even do it to other witches. In Wyrd Sisters, after an attempt at some complicated mental magic by Granny Weatherwax fails to work on the Duchess, Nanny Ogg deals with her by hitting her over the head with a cauldron so the guards can arrest her. Maskerade has an example from someone who's not a witch; Walter Plinge is asked "if your house was on fire what would you take out?" and answers "The fire!"
- This is one of Captain Carrot's defining traits. At the start of the Watch sequence, he really is naive to the ways of the city, arresting the head of the thieves' guild for thievery and not recognizing that his boarding house is actually a brothel, but he also takes literally Vimes' order to "throw the book at [Wonse]", while Wonse is at the edge of a three-story drop. As the books progress he wises up, but continues to act in a very simple matter. To free a golem, he puts its receipt of sale in its head, to stop a war, he suggests arresting the armies for breach of the peace. And it all works.
- Samwise Gamgee of The Lord of the Rings has plain good hobbit-sense, even more than the other three hobbits because he's a simple gardener and not in the gentry. When forced to carry the Ring himself for a time, it naturally tempts him and chooses to do so with visions of Mordor as a beautiful garden. Sam considers it and then shakes his head because he could never manage a garden that vast on his own. And when the Ring tries to tempt him with the idea of having hordes of servants to manage the garden for him, Sam shrugs that off because if other people are doing the actual gardening, then it wouldn't be his garden.
- This trope shows up in The Hobbit as well. As Thorin Oakenshield is dying from wounds he received during the Battle of the Five Armies, he remarks that Bilbo has "some wisdom and some courage, in equal measure." Thorin goes on to say this about hobbits and their Arcadian lifestyle as a whole, remarking that "if more of us valued food and cheer and song over hoarded gold, this world would be a merrier place."
- Horace Altman of Ranger's Apprentice has a fair bit of this. While not a Guile Hero or The Strategist like his Ranger friends, he's intelligent and sensible in his own way, and methodically thinks through problems while Will jumps from one idea to another.
- Sheriff Carter, from Eureka. It's the whole point of having him as the sheriff in a town of full geniuses with too much brains and not enough sense.
- Jack O'Neill of Stargate SG-1 often falls into this. Although he's also smarter than he lets it show.
- Merlin from Merlin is a subversion. Everyone thinks this of him, but he's actually The Smart Guy.
- Edith Bunker, of All in the Family, might be the patron saint of this trope. She lived with her blue-collar, bigoted husband Archie, feminist daughter Gloria, and liberal, atheist son-in-law Mike, and often seemed uninformed or unaware of the major political and sociocultural debates that the other three had. However, Edith was often the only person who was able to apply practical, plain-spoken solutions to issues, whether it was solving a riddle about a female doctor, not allowing racism to tint her opinions while she served on a jury, or defusing a potentially catastrophic argument by rhapsodizing about maple syrup. She also embodied the principles of kindness and embracing those different from her (without being condescending, as Mike tended to do) that the rest of her family could get too caught up arguing about to practice. For example, Edith happily called the African-American Louise Jefferson her best friend while their respective husbands refused to even speak to each other, "adopted" the gay drag performer Beverly Leslie as a member of her family, and immediately accepted her lesbian cousin Liz's longtime relationship with her "roommate" Veronica as completely legitimate. It's not for nothing that critics considered Edith, who spoke plainly but wisely, the "anti-Richard Nixon," who was very intelligent but widely perceived to lack honesty and common sense.
- The Golden Girls often did this with both Rose and Sophia. Rose's common sense usually helped her play peacemaker between Dorothy and Blanche (whose polar opposite personalities could lead to trouble) and perceive other people's lies. Sophia, meanwhile, was unafraid to frankly state what was going on rather than being tactful; while this occasionally rubbed people the wrong way, her approach was far more effective than any Zany Scheme the others cooked up.
- Much of the humor of The Big Bang Theory stems from this trope. Sheldon, Leonard, Howard, and Raj are all geniuses in various scientific fields and uber-nerds, but they lack social skills and awareness of anything outside their spheres (Sheldon, for instance, has no idea who Radiohead is), and generally get so caught up in their own projects and brains that they run into countless issues. In contrast is Penny, Sheldon and Leonard's extremely attractive neighbor and a waitress/would-be actress who didn't even finish community college in Nebraska—but what she lacks in formal education, she more than makes up for in wit and practical knowledge. In one instance, she is able to recover all of Sheldon's hacked World of Warcraft items by kicking the guy who stole it in the crotch (after the guys failed to do so using nerdy threats); in another, the guys turn to her when they need some help learning how to fish.
- The later seasons play this up even further with Amy Farrah Fowler, who starts out as a female version of Sheldon. She and Penny are polar opposites in every way, but the two gradually become best friends, with Penny's "girly" personality and more traditionally feminine wisdom contrasting with Amy's dour demeanor and purely cerebral worldview (the latter has to look up how to have a slumber party, for instance). In just one example, Amy doesn't know how to settle an argument she's having with Sheldon, so Penny teaches her the valuable art of making a scene in public (which she's apparently mastered to the point of being banned from three separate Chili's restaurants).
- Even Sheldon and Leonard's mothers get in on this trope. Beverly Hofsteader, Leonard's mother, is a genius sociologist/anthropologist, as well as an extremely frigid person who's almost robotic in her complete lack of affection for anyone and anything (her advice to Leonard when he's going through a tough time? Telling him to "buck up, sissypants" and buy her books on Amazon). Sheldon's mother Mary, by contrast, is a sweet-natured and cheerfully bigoted Baptist Christian from the "Bible Belt" of Texas, and rarely understands anything her son and his friends are doing. Needless to say, Mary is far more adept at solving problems than Beverly; for starters, she actually considers other people as human beings rather than test subjects.
- Mary has this relationship with Sheldon, too. Her son may be a genius, but Mrs. Cooper is able to easily sort out Sheldon's overthinking, neurotic behavior with some plain wisdom and occasional trickery. In one instance, Sheldon and Amy break up, prompting the former to adopt dozens of cats to make up for the void, all while denying any problem. Mary comes at Leonard's request and, after assessing the situation, invites Amy for dinner, then tells the pair that it's a good thing they've separated, as they're clearly a terrible match for each other. A stunned Sheldon disagrees and promptly makes up with Amy to prove Mary wrong—which is naturally just what she expected her son to do.
- The West Wing features a downplayed example with Donna Moss, Josh's assistant. She's quite intelligent and not "simple" at all, but she's also extremely new to the world of government as opposed to the rest of the main cast, who are longtime political players. As such, she often ends up asking questions about particular procedures or policies in the White House (which in turn helps the audience make sense of them, too). However, Donna's non-political perspective often allows her to see things more clearly than her colleagues, who can get too caught up in their own agendas to see easier solutions or the views of the people they supposedly represent. For instance, in "20 Hours in America," Donna, Josh, and Toby miss their flight back to D.C. and have to travel across the Midwest via trains and cars; along the way, they meet various individuals who are being affected by the White House's policies. Donna is the only one who actually listens to what those people are saying and the problems they've faced, whereas Josh and Toby are too busy arguing about the "big picture" and abstract theory to notice. Toward the end of the episode, she calls the guys out for their insensitivity, and they take the lessons to heart, as shown when Toby sits down for a drink with a local man and has a genuinely compassionate chat about the difficulties he and his children are having.
- Donna was also able to occasionally come up with simple solutions to knotty political problems by pointing out easy but overlooked tactics. In "The Stackhouse Filibuster," for example, she finds a way to help the titular Senator continue his speech by pointing out the rule that he's able to take questions as part of the filibuster, and further that there's nothing that states how long those questions need to be. Sure enough, the White House staff is able to get other Democratic Senators to ask Stackhouse twenty-plus part questions, saving the day.
- As mentioned above, Dungeons & Dragons can invoke this when a character with low Intelligence has a high Wisdom score. The closest analogue for these stats are IQ vs. EQ, with Intelligence representing things like knowledge, education, and problem-solving while Wisdom is more about empathy, introspection, and the ability to read motivations in others.
- In the first Knights of the Old Republic, you get questions to see what kind of Jedi you'll be. None are "wrong", but guess which answer here leads you to become the wisdom-seeking, magelike Jedi Consular:
There is a locked door, and you need to get to the other side. What do you do?
1. Blast it open.
2. Hack into the lock to get it open.
- Final Fantasy V's protagonist, Bartz, is described in the manual as a "simple wanderer." He has some Book Dumb traits, but he also has a very uncomplicated and un-angsty outlook on saving the world. For instance, when Krile's wind drake will die if not treated with a plant that only grows in a place so dangerous no one has ever returned from it, it sends the party into a brief despair, until Bartz breaks it with these words:
"Guess that means we'll be the first who do!"
- Sera from Dragon Age: Inquisition occasionally makes surprisingly profound statements based on straightforward observations, stumping even the more book-smart party members. For example, when Solas badgers her one conversation too many about organizing the Red Jennies to dispose of the nobility for good:
Sera: What, just lop off the top? What does that do, except make a new top to frig it all up?
Solas: I... forgive me. You are right.
- This exchange becomes even more tragic in hindsight after you learn Solas's backstory; it turns out that his actions against the elven "gods" in the distant past resulted in pretty much this.
Twisted Metal:Head-On Cousin Eddy, a mentally deficient Hillbilly, wins Twisted Metal. Typically this is where Calypso Would grant a wish that he would oh so horribly corrupt in various ways (Most endings in the series, outside of the First game Twisted Metal 1 and the malevolent wishes in Twisted Metal: Black, are not granted as the wisher intended, and even fewer actually outsmarting Calypso at his own game.). Cousin Eddy points at his Vehicle and simply asks 'Make it better.', This after Calypso initially refusing to grant his wish due to not having been invited to the tournament (As far as this troper is aware, he is the only example of this in the ENTIRE SERIES.), and after being 'Persuaded' (And by this I mean Cousin Eddy threatens to break his neck.), he does so reluctantly. Unfortunately for Calypso, and ABSURDLY LUCKILY for Cousin Eddy, Despite the even higher than usual motivation Calypso probably had to screw him over, there's not alot of leeway in terms of alternate interpretations for "Make it better." Which forces Calypso to grant him his wish without his usual dickery. Calypso laments the turn of events in this ending.
- In The Inexplicable Adventures of Bob!, this is very nearly Bob's most prominent personality trait.
- Patrick Star from SpongeBob SquarePants. Before Flanderization kicked in, anyway.
- Pinky, from Pinky and the Brain, on those rare times when he is pondering what Brain is pondering.
- While usually the Cloudcuckoolander, Pinkie Pie sometimes has shades of this in My Little Pony: Friendship Is Magic (see above quote). This is actually a recurring element of her character, where her friends (and others around her) write off a lot of what she does as simply being goofy and silly, only to be surprised when they see the stroke of genius in her madness (such as when she lead the Parasprites out of town by using the Pied Piper routine on them that the rest of the cast didn't think to or wrote off as being too outlandish).
- Stan Marsh from South Park, although he's not an idiot like most examples.
- Butters Stotch is a straighter example in recent episodes.
- Darwin of The Amazing World of Gumball, though still very dippy, sometimes shows more awareness and concern of the dumb antics he and his brother Gumball get caught into. On rarer occasions Gumball himself can apply.
- Nug of the Urpney squad in The Dreamstone. He's rather vacuous, but he usually can point out the simplest (and often correct) solution to problems, which Blob usually steals credit for. He also has a slightly more unnerving savviness for potential morbid fates they can suffer.
