mayos do this all the time with population genetics (aka actual race science)

there'll be a continuous spectrum of different DNA, and they'll contort their minds into making random clusters that just line up with the made-up categories that they already perceive as their reality. For example, they'll undersample the Turkish population just so it looks like "West Asia" and "Europe" are separate, when in reality there's a bunch of western Turks that literally aren't shown, which genetically connect Greece and Turkey.

That's why NewZealand and Iceland are in totally different clusters despite being equivalent lol.
