>>10825534That's garbage used to manipulate dumb people, there are no sources. Not that the premise is incorrect, just that particular image has no business being presented as some sort of truth. It's like a graph with no labels on the axes.
If you look at the field of forensics, specifically the guy whose job it is to identify a stripped skeleton found in the woods, that guy knows you can tell black skulls apart from caucasian skulls apart from asian skulls, to a limited degree. Skulls being different doesn't have to mean anything though, you can ask an HVAC guy about the studies they've done showing white and black people prefer different air temperatures, and you just set the temperature to match the demographic of the people going into your building. Who gives a shit, it's not important.
