Who had the higher IQ?

By the most cited estimates, Bernhard Riemann tops this matchup with an estimated IQ of 180, a 10-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.

Achievements compared

Adam Smith is best known for: Invisible hand theory, The Wealth of Nations and The Theory of Moral Sentiments Bernhard Riemann is best known for: Riemann–von Mangoldt formula, Riemann bilinear relations, Cauchy–Riemann equations, Free Riemann gas, Pseudo-Riemannian manifold, Riemann's differential equation

Different eras, different boards

The two were born roughly 103 years apart (1723 vs 1826), 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, Bernhard Riemann 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.
