Who had the higher IQ?
By the most cited estimates, Werner Heisenberg tops this matchup with an estimated IQ of 180, a 10-point margin over Mark Twain (170). IQ estimates for historical figures are reconstructions, not test results — they sit on top of biographical evidence, productivity, and the difficulty of the problems each person solved. Treat the number as a directional signal, not a verdict.
