But this is wrong. For one thing, it imposes a really bad framework on human difference. Looking at the distribution of traits between groups, there’s a spectrum of difference, with frequency of traits rising and falling over distances rather than starting and stopping with firmly defined boundaries. Races, in short, don’t look like distinctive groups but rather points along a spectrum. Moreover, the underlying genetics don’t match the idea of race, which is not surprising, since the people who created the idea of race didn’t have a clue about genetics.

Rather, it’s a cultural construct, a categorization based on arbitrarily selected visible traits, but it doesn’t have deeper significance than that. The racial categories under which we currently suffer were created during the early modern period and eventually codified as pseudoscience in the 18th century.
