You skipped my comment on "cultural".

Race is entirely a social construct. You can't do a genetic test and with certainty determine someone's race. Certain genetic traits are common among what we call races, but not exclusive.

Take a look at services like 23andMe or other services, the genetic components of race are entirely based on self-reporting, that is, we call certain genes "Asian" because people who identify as Asian had those.

It's entirely tautological.

Suppose you are looking at a 52 card deck, and members of each of the four “shapes” self-identify (with some random noise, and maybe even systematic deviations — like sevens and aces are identified differently from just their shape, etc) as different “suits”.

The pairing between shapes & suits will of course be tautological because the names of the suits are cultural artifacts, but the shapes would still be distinct regardless.

This seems confusing and contradictory. If traits are common in certain groups and not in others (needn’t be exclusive), then by Bayes rule these traits should identify groups with high probability (especially when combining multiple traits)

But genetic testing doesn't identify groups with high probability, because the overlap is so high. And it often misidentifies racial groups because of that.
