How we ranked them

Each estimate follows the same five-part test: abstract reasoning, planning under uncertainty, learning speed and breadth, invention, and how often the character is outplayed. Being told that a character is a genius earns nothing, and repeated mistakes cost points.

A universe of self-declared geniuses, where the title is handed out far more freely than the evidence supports. Ranking the cast together makes the trade-offs visible, because the same story gives every character the same chances to prove themselves. The rules are on the method page.

Smartest Marvel characters, ranked: common questions

Who is the smartest Marvel character?+

On our evidence, Reed Richards at about 175, ahead of Bruce Banner at 165. The order depends on what you weigh, so each profile lays out the scenes and the mistakes behind its number.

How do you estimate a Marvel character's IQ?+

We score what the character does on screen: deduction, planning, learning speed, invention and how often they are outplayed. We then map that to an IQ band with a range and a confidence level. It is fan analysis, not a measurement.

Are these the official Marvel IQs?+

No. The story does not state IQs for these characters, so every figure is our own estimate with a range.

Why do the estimates differ from fan claims?+

Fan numbers usually reward how impressive a character seems and ignore their mistakes. Ours count being outplayed as evidence, which pulls most numbers down.
