Adam Smith vs Enrico Fermi
Adam Smith (IQ 170) vs Enrico Fermi (IQ 190). Side-by-side comparison of intellect, achievements, era and cultural impact.

Who had the higher IQ?
By the most cited estimates, Enrico Fermi tops this matchup with an estimated IQ of 190, a 20-point margin over Adam Smith (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.

Recognition. Adam Smith: —. Enrico Fermi: Matteucci Medal (1926) • Nobel Prize (1938) • Hughes Medal (1942) • Medal for Merit (1946) • Franklin Medal (1947) • ForMemRS (1950) • Barnard Medal for Meritorious Service to Science (1950) • Rumford Prize (1953) • Max Planck Medal (1954).
Different eras, different boards
The two were born roughly 178 years apart (1723 vs 1901), 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, Enrico Fermi 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.
