A jock isn't always a jerk. Sometimes he is instead (or as well) Book Dumb (at best) or is Too Dumb to Live at worst. Much like his girlfriend, The Cheerleader of the Brainless Beauty variety, he's more concerned with his image than school work. If he's not a jerk it might be because he's too dumb to realize he's supposed to be (though the Jerk Jock can also be incredibly stupid like the caveman mentality of the Dumb Muscle). Often times the better he is at his respective sport, the dumber the jock is like a Genius Ditz and the more valued he is by his team and the facility who will make sure that he maintains his position regardless of his apparent mental incompetence.
While The Cheerleader can easily be dumb, the word jock refers to a player of rather aggressive sports, primarily football.
This belief likely stems from the idea that high school and college athletes are too busy training to do homework and that talented athletes are given special treatment by the school system so they don't need to study. Or perhaps because the physically-intimidating bully is more likely to turn to sports than the stereotypical nerd. Or it could simply be the concept of Competitive Balance being applied to real life. This trope is almost completely restricted to team sports and boxing or wrestling. Individual sports practitioners are likely to fall on its inversion: Academic Athlete.
Can overlap with Jerk Jock and Dumb Muscle, if he's part of the 'cool kids' crowd. Also the spear counterpart to the Brainless Beauty and The Ditz when applied to a cheerleader (who's usually his girlfriend). Always Male because a girl is more likely to be somewhere between the Girl Next Door or a Lesbian Jock who, while tough, is mentally competent.
Anime and Manga
- Eyeshield 21:
- Otawara is the embodiment of this trope. The guy's so dumb he forgets to wear pants on a daily basis, but got a sports scholarship at Ojou by being one of the fastest and strongest nose guards in high school football.
- To a (slightly) lesser extent there's Taki of Deimon, Kamagaruma of Taiyou, Homer of Nasa, and Achilles of Teikoku.
- Slam Dunk: Four of the five starting players for Shohoku are of the Book Dumb variety. Ironic, considering that until that year Shohoku's basketball players were known for their respectable grades (of course until that year they had been a rather terrible team).
- Discussed in Yo-Kai Watch when Whisper mentions he believes in the phrase "The bigger the muscle, the smaller the brain".
- Moose from Archie Comics fits this trope to a T. And he knows it.
- In Tintin, one of Captain Haddock's many, many technically-insults is "complete athlete!", meaning someone who practices many different sports suffers in his intellectual development.
- In the Jonni Thunder AKA Thunderbolt mini-series, Slim Chance's bodyguard is an former pro linebacker named 'Roadblock' Ramsey. When Jonni sarcastically asks him if he still holds the record for the most passes intercepted with his head, he starts to reply "Well, it's not official, but...". Slim has to stop him and explain she was just joking.
- The Blind Side is an example of the teachers helping Michael Oher pass his classes so he can play football.
- Lump Hudson in the Coen brothers' remake of The Ladykillers. His Establishing Character Moment is what ends his football career.
- Daniel, Adrian, and Paul in Pain and Gain are three bodybuilders who are also incredibly stupid, which ends up being the main reason their plot falls apart.
- In Monsters University, Sulley is talented at Scaring, but starts out incompetent at actual performance.
- Wes in The Duff, whose football scholarship will be lost if he doesn't pass chemistry. He doesn't seem to have a very good grasp on any intellectual activity or even the English language, but is very competent in a field of popularity.
- While decidedly a nice guy, Mitch of ParaNorman is not the brightest bulb in the box. Throughout the film he remains utterly oblivious of the affections of Norman's sister. Of course, this might also be because has a boyfriend.
- Harry of The Dresden Files believes Hendricks, Gentleman Johnny Marcone's primary enforcer, to be one of these. He fits all the stereotypes: large, no neck, close cropped hair cut, speaks mainly in grunts and intimidating glares, and used to play football in high school. However, it's later revealed that he's actually quite intelligent, just The Stoic, and is at one point seen working on his Master's thesis.
- P. G. Wodehouse's character Mike Jackson, who appeared in the Psmith series. He's more Book Dumb than anything else, but his parents and teachers blame his failing grades on his passion for cricket, at which he excels.
Live Action TV
- Our Miss Brooks has Stretch Snodgrass. Snodgrass is a basketball, baseball, and football star. He's good natured, but dimwitted to the point of being Too Dumb to Live.
Miss Brooks: Stretch has always been a puzzle to me. I've never understood how a mind that can remember so many complicated football plays has so much such trouble spelling the word cat!
- Up to Eleven on Blue Mountain State. Most of the football team is barely literate and only pass classes because arrangements have been made for better students to do their classwork for them. When the nerds go on strike, the team finds themselves in serious academic trouble.
- Glee has football players Finn and Puck, but is inverted with Mike, who is a straight-A student.
- Probably because he's Asian.
- There is an episode of Sabrina the Teenage Witch where Sabrina writes an article for the school paper exposing the preferential treatment given to school athletes and gets the star pitcher for the baseball team benched until he finishes his assignments. She goes to help him and he has doodled that he hates her and wrote her names with three "n"s.
- Arrested Development : "Steve Holt!"
- In the Canadian tv movie Net Worth, Gordie Howe is the best player in the NHL and not too bright. This is played both for laughs (Comically Missing the Point several times) and for drama (being manipulated into betraying a players union). Apparently the real Gordie Howe was not very happy with the film for that reason.
- Letterkenny has Riley and Jonesy, two incompetent hockey players who always get blasted with insults by Wayne and Daryl that often go over their heads.
- Peppermint Patty from Peanuts often found herself here. Her report card was often full of D-'s, is prone to incredibly boneheaded misunderstandings, and was clearly the most athletic and athletically inclined of the cast; one TV special had her plan most of the football team's offense as 'hand me the ball as I run up the middle'..and it worked.
- The Party Zone includes a wayward football player on the playfield. He also shows up periodically in the animations.
- Frank Stone from the Cool Kids Table game Creepy Town. In his first appearance he confuses forceps for a scalpel. He admits that he was just hired to lift heavy stuff. He also hesitates when Stacey asks if anyone is a ghost, and the others accept the possibility that he doesn't know if he is.
- Ethan Wright falls under this as well, though he's not quite as dumb as Frank and also nicer than him.
- In "Pass the Football" from Wonderful Town, the Wreck claims to be a literally monumental college football star, despite having bad manners and worse grades.
Couldn't write my name,
Couldn't translate "je vous aime,"
Never learned to read
Mother Goose or André Gide,
But I could pass that football
Like nothin' you have ever seen.
- Gary in Escape From St. Mary's has trouble remembering the injuries he experienced just minutes ago, among other intellectual shortcomings.
- In Half-Life, the graffiti the Marines leave on the walls to intimidate Gordon are full of misspellings.
- Monster Prom: The whole football team seems to be composed of these, with Scott being the most dimwitted Love Interest of the game, albeit also the nicest, while his cousins that make up for the rest of the team, The Wolfpack are as dumb as him, but much more mean.
- Alex from Stardew Valley isn't the most scholarly guy around, and turns out to have a bit of a complex about it.
- Johnny from Mr. Massagy certainly isn't the brightest bulb in the box.
- The eponymous Homestar Runner is "a terrific athlete", but is dumb enough for Strong Bad to devote an entire Strong Bad Email ("4 branches") to some of the stupidest things Homestar has done. These include accidentally getting stuck inside a water cooler and reciting the mathematical formula for Coloumb's Law when asked "What's two plus two?"
- Jeremy from Ozy and Millie.
- Subverted by early years antagonist Vin Vulpen in Kevin & Kell, he's (usually) a muscle-bound athlete but is also a genius programmer and biochemist. Of course his muscles were initially caused by steroids.
- Dash and Kwan from Danny Phantom.
- King of the Hill:
- Defied in an episode where a star high school football player is given a pass on all his classes just so he can play; it's taken as a given that he couldn't pass the classes on his own merits. He doesn't realize that this is happening though, and once he finds out, he's upset and offended that nobody aside from Peggy had any faith in his learning abilities— including his own mother, who played him off as developmentally disabled to trick Peggy and Hank. He then tries to succeed on his own with their help.
- Joseph Gribble was eventually flanderized into his.
- Daria's Kevin Thompson is easily a finalist for the dumbest living organism in Lawndale. While not a bully, he's a little narcissistic, dumb as a box of rocks, wears his uniform everywhere, and is in general bad at everything that isn't football. At least he's sweet to his head Cheerleader girlfriend, Brittany, genuinely friendly to his teammates, and amicable towards everyone else, even the unpopulars.
- Meat in Sym-Bionic Titan. He's not a Jerk Jock though, he's actually quite fond of the nerdy Newton.
- Lawson from Recess
- Kleet in Dude, That's My Ghost! is a textbook example.
- In Nerds and Monsters, Stan - the only kid who is not a nerd - is the linebacker on the Beaverton Bulldogs team and stereotypical dumb jock. He has been known to put his pants on his head by mistake while getting dressed.
- The Loud House: Lynn is the sports star of the Louds. In "The Butterfly Effect" Lincoln predicts that if Lisa doesn't tutor Lynn, she'll flunk miserably in all her classes.
- Has a tendency to become Truth in Television due to the fact that the human brain is a rather delicate instrument that can only take so many blows (after all, there's a reason it's tucked away inside a hard skull). When your sport involves a lot of ramming, bashing, punching, or sudden starts and stops, all that violent pounding on your head can start to take a toll on the number of healthy neurons in there. The number of concussions over a lifetime can also result in a downward-trending IQ, and so retired athletes from sports like football, boxing, or hockey are often a touch less smart than they were when they started - of course, don't try to tell them that their favorite sport and lifeblood has made them dumb.
- Due to the sheer amount of time spent training for their sport of choice, especially on the professional (and high collegiate) level, it can leave very little time to pursue intellectual interests, while simultaneously ignoring them (mostly) in their field of work to begin with.
- Additionally, the popularity and support of athletic endeavors in many schools is extreme enough to lead some teachers to either "help" athletes out or feel uneasy about giving bad marks when earned, thus eliminating the apparent negative impact of focusing on the game. In extreme cases, good players have "passed" classes despite being functionally illiterate.
- Overdeveloping your neck and shoulder muscles will restrict blood flow to the brain.
- Not to mention in America, many athletes only go to college because they're required by the leagues. No professor wants to be the guy to fail the guy that essentially pays his salary.
- As Charles Barkley once said: "How am I gonna lead the SEC in rebounding if I was in class?"
