It's pretty clear that our genes affect, though they don't completely determine, who we grow up to be; children’s physical and mental characteristics are not completely unrelated to those of their parents. But this relationship has been widely abused throughout history to underwrite racist and sexist ideas. So there has been a counter-reaction in the direction of removing any consideration of genetic heritage from how we understand people. Kathryn Paige Harden argues in favor of a more nuanced view: DNA does matter, we can clearly measure some of its effects, and understanding those effects is a crucial tool in fighting discrimination and making the world a more equitable place.
