Science confirms: Ancient Greeks had the highest IQ of ancient West Eurasian populations (featured in this particular study).

See supplementary materials here for some more polygenic scores, intracranial volume, schizophrenia, neuroticism, autism, etc.: researchgate.net/publication/37…
Here's the change in height and IQ over time:

Ancient vs modern Greek ancestry: Indo-Europeans arrived in Greece around the Middle Bronze Age; ancient Greeks had some Near Eastern ancestry via Bronze Age Anatolians; Roman-era Greeks had even more; modern Greeks have Slavic ancestry, so higher Steppe than ancient Greeks.

Ancient Greeks scored lower on the other cognitive ability PGS (educational attainment) btw; study said this disparity requires more investigation. Republic-era Romans scored the highest for EA, second highest for IQ, so maybe they were the smartest? Sorry, I clickbaited you.

EA correlates ~0.8 with IQ, so it's a reliable proxy.

Used the wrong steppe sample for ancient Greeks.
