Who had the higher IQ?

By the most cited estimates, Alan Turing tops this matchup with an estimated IQ of 185, a 10-point margin over Baruch Spinoza (175).

Treat the number as a directional signal, not a verdict.

Different eras, different boards

The two were born roughly 280 years apart (1912 vs 1632), 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, Alan Turing 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.
