However, It depends what you are measuring, and what scale you are using. Use a scale like Busy Beaver IQ and almost everyone is below average. Because you are streaching out differences at the top of the scale.
There is also a difference between biological intelligence and optimization power. A caveman with the genes for being unusually smart still won’t know much science. It is at least plausible that the median is less than the mean here, but again, it depends on the scale used.
