I think it’s less that it’s impossible but more that we don’t have any clue as to what causes differences among groups and many people use such measured differences as evidence for pretty deplorable ideas. There’s much more evidence for social determiners than anything biological. Everyone outside of Africa shares a single ancestor 20,000 years ago. There’s far more genetic diversity within Africa than the rest of the world. That alone is often enough to disprove many theories regarding racial differences since our intuitive understanding of “genetic difference” is so flawed.

Past research has a eugenicist bias because early statisticians were eugenicists seeking evidence for the ideas. I would argue that’s why the social determiners research is valuable to help offset that.

Because if you give an inch to that line of thinking, it leads to broader dehumanization and mass tragedy.

This is a good point.

There are times where lefties will deny science in an effort to avoid mass atrocities, which I think is a fraught situation.

Inversely, righties tend to deny science in order to justify mass atrocities (like industrial-scale animal suffering or cataclysmic extinction events).

These are basically the same thing! /s
