Science tells us that race is in our heads, not in our genes; it’s all a social construct.
It’s an observation that seems to illuminate everything and nothing at once. It makes it sound so arbitrary and trivial—a trick of the mind. And yet history tells us that race has mattered enormously. And the news emphasizes how much it still matters today in terms of what researchers call “life outcomes”: Your chances of securing a loan, for example; or of getting a good education; or of being shot by the police.
