| Estimated IQ | 190 | 185 |
| Best known for | Sharing the 1933 Nobel Prize in Physics with Erwin Schrödinger "for the discovery of new productive forms of atomic theory" | Psychoanalysis, including the theories of id, ego and super-ego, oedipus complex, repression, defense mechanism |
Who had the higher IQ?
By the most cited estimates, Paul Dirac tops this matchup with an estimated IQ of 190, a 5-point margin over Sigmund Freud (185). 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.

Different eras, different boards
The two were born roughly 46 years apart (1902 vs 1856), which matters: scientific tools, available knowledge, and intellectual culture compound. Comparing minds across eras is comparing players on different boards.
The verdict
So who was greater? The honest answer: they're not strictly comparable. By raw IQ proxy, Paul Dirac edges out. By measurable, lasting influence in their respective field, both are anchors of the human record. If you have to pick one to bet civilization on, pick the one working on the problem you care about.
