Who had the higher IQ?
By the most cited estimates, Aristotle tops this matchup with an estimated IQ of 200, a 70-point margin over Carl Sagan (130).

Different eras, different boards
The two were born roughly 1550 years apart (0384 vs 1934), 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, Aristotle 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.
