How we ranked them
The ranking uses one rubric for everyone: abstract reasoning, planning under uncertainty, learning speed and breadth, invention and how often the character is outplayed. It is designed so that a character who is told to be a genius, but never shown solving anything, cannot outrank one who wins by thinking.
Characters that are superhuman by design, such as androids and AIs, are ranked but flagged, because a human IQ scale does not measure them. Estimates for teenagers are age-normed at their age in the story.
Stated IQs from the shows themselves appear in the table at the end. Where they differ from our estimate we say why. The full rules are on the method page.

Off the human scale
These characters are superhuman by design, such as machines and alien minds. A human IQ number does not describe them, so they are listed apart from the ranking and their figures are for reference only.
Why each one sits where it does
1.Rick SanchezRick and Morty
IQ 180Rick Sanchez's IQ is best estimated at about 180 (range 170 to 190): the most inventive mind in his corner of the multiverse, undercut by his own baggage and blind spots.
2.Reed RichardsMarvel
IQ 175Reed Richards' IQ is about 175 (range 165-185): the widest scientific range in Marvel, offset by errors of judgement that would sink a smaller reputation.
3.OzymandiasWatchmen

7.Senku IshigamiDr. Stone
IQ 165Senku Ishigami's IQ is about 165 (range 155-175): the widest scientific knowledge and fastest practical invention in his cast, discounted for a story that keeps handing him what he needs.

17.Spencer ReidCriminal Minds

22.Lelouch vi BritanniaCode Geass
IQ 150Lelouch's IQ is about 150 (range 140-160): a gifted tactician who plans well and improvises brilliantly, but leans on Geass and is repeatedly blindsided by family and by allies.

IQ 150Tyrion Lannister's IQ is about 150 (range 140-158): the sharpest political and tactical mind on the board for much of the story, but an emotional decision-maker when it counts.
25.Gregory HouseHouse M.D.
IQ 148Gregory House's IQ is estimated at about 148 (range 135-158): elite diagnostic reasoning across many specialties, held back by how often he is wrong for most of an episode.

27.Hermione GrangerHarry Potter

29.Johan LiebertMonster
IQ 145Johan Liebert's IQ is roughly 145 (range 130-160): a gifted manipulator whose greatest feats are psychological and hard to measure, which is why the estimate is wide.
30.Petyr Baelish (Littlefinger)Game of Thrones
IQ 145Petyr Baelish's IQ is estimated at about 145 (range 132-156): elite manipulation and financial scheming, undone in the TV show by overconfidence about people he thought he had read.
31.Shikamaru NaraNaruto
IQ 145Shikamaru Nara's IQ is best estimated at 145 (range 135 to 155): a first-rate tactician whose preparation beats stronger enemies, but not quite the flawless 200-plus genius the canon line suggests.

IQ 145Shinichi Kudo's IQ is best estimated at 145 (range 132 to 158): an exceptional detective with hundreds of solved cases, outplayed at the start and still short of closing his main case.
33.Walter WhiteBreaking Bad

35.Izaya OriharaDurarara!!
IQ 140Izaya Orihara's IQ is best estimated at 140 (range 128 to 152): a gifted manipulator of gangs and rumours, but stabbed, outplayed and undone by his fixation on Shizuo.
36.Lisa SimpsonThe Simpsons
IQ 140Lisa Simpson's IQ is best estimated at about 140 (range 125 to 155), a little below her stated canon score of 159: clearly gifted, but often more certain than she is clever.
37.Frank UnderwoodHouse of Cards (US)
IQ 138Frank Underwood's IQ is estimated at about 138 (range 126-148): superb political and psychological strategy, but a career built on leverage rather than deep reasoning, and a stalled presidency.
38.MelloDeath Note
IQ 138Mello's IQ is around 138 (range 128-148): a gifted, aggressive problem-solver who gets results the cautious cannot, and who pays for the risks.
39.Kaguya ShinomiyaKaguya-sama: Love Is War
IQ 135Kaguya Shinomiya's IQ is best estimated at about 135 (range 122 to 148): a near-top student and precise planner, held back by pride and a habit of overthinking tiny stakes.
40.Satoru GojoJujutsu Kaisen
IQ 135Satoru Gojo's IQ is best estimated at 135 (range 120 to 150): a gifted innovator and teacher whose strength far outruns his strategic judgement, and who is twice caught by traps.

IQ 135Saul Goodman's IQ is estimated at about 135 (range 122-148): outstanding verbal and social intelligence and quick improvisation, but his schemes collapse when emotion gets involved.
42.Solid SnakeMetal Gear
IQ 135Solid Snake's IQ is best estimated at about 135 (range 122 to 148), well below his profile-stated 180: an elite operator who keeps being played by people on his own side.
43.Gordon FreemanHalf-Life
IQ 130Gordon Freeman's IQ is best estimated at about 130 (range 115 to 145): a credible MIT-trained physicist, but a silent hero whose puzzle-solving is done by the player, so confidence is low.
44.Killua ZoldyckHunter x Hunter
IQ 130Killua Zoldyck's IQ is best estimated at about 130 (range 118 to 145): a fast learner and sharp tactician whose reasoning is real but narrower than the genius label suggests.
45.Okabe RintaroSteins;Gate
IQ 128Okabe Rintaro's IQ is about 128 (range 118-138): sharp, stubborn and a superb leader, but the real scientific talent in his lab is Kurisu, and his defining power is not intellectual.
46.Naruto UzumakiNaruto
IQ 118Naruto Uzumaki's IQ is best estimated at about 118 (range 105 to 132): weak on academics and deduction, but a genuinely creative improviser who is unusually good with people.
47.GokuDragon Ball
IQ 108Goku's IQ is best estimated at about 108 (range 98 to 120): average outside combat, but with exceptional learning speed and improvisation once a fight starts.
Off scaleMeruemHunter x Hunter
IQ 200Meruem's IQ is placed at about 200 (range 185 to 220), but as a non-human by design human scales do not really apply. He learns and adapts faster than anyone we cover.
Off scaleGLaDOSPortal
IQ 195GLaDOS's IQ is best rated at about 195 for ranking only (range 175 to 215): a superhuman machine intelligence whose repeated misjudgements of one test subject keep her from being flawless.
Off scaleDataStar Trek: The Next Generation
IQ 180Data's IQ is roughly 180 (range 170-192), but as an android he sits outside the human scale: his memory and speed are superhuman, while his judgement, though strong, can be beaten.
When the story states an IQ, and we disagree
Some fictional characters come with a number. Here is what the story says next to what the evidence supports.
| Character | Canon states | Our estimate | Gap |
|---|---|---|---|
| Sheldon Cooper | 187 | 155 (142 to 168) | +32 |
| Spencer Reid | 187 | 152 (140 to 163) | +35 |
| Shikamaru Nara | 200 | 145 (135 to 155) | +55 |
| Lisa Simpson | 159 | 140 (125 to 155) | +19 |
| Solid Snake | 180 | 135 (122 to 148) | +45 |
Smartest fictional characters, ranked: common questions
Who is the smartest fictional character of all time?+
Among characters on a human scale, our evidence ranks Rick Sanchez (Rick and Morty) highest, at about 180. Superhuman characters, such as AIs and androids, rank higher on paper but cannot really be compared with a human IQ.
How can a fictional character have an IQ?+
It cannot be measured, so it is an argument. We look at what the character does, weigh mistakes as well as feats, and map that to an IQ band with a range and a confidence level. Some series state a number, and we treat that as a story fact.
Which characters have an official IQ?+
A handful. Sheldon Cooper and Spencer Reid are both stated at 187, Solid Snake at 180 and Lisa Simpson at 159. The table above compares each with our estimate.
Why are the estimates lower than fan claims?+
Fan numbers often reward how impressive a character seems and ignore mistakes. Our method treats being repeatedly outplayed as evidence, so numbers of 200 or more are reserved for characters who are superhuman by design.
How do I find my own IQ?+
Only a supervised test can give it. A fast first look is a reasoning test: LifeScore has a 25-question visual test that takes about 12 minutes.
