Racism thrives on our not knowing this.
Racist pseudoscience is on the rise—fueling hatred, feeding nationalism, and seeping into our discourse on everything from sports to intelligence. Even the well-intentioned repeat stereotypes based on “science,” because cutting-edge genetics are hard to grasp—and all too easy to distort. Paradoxically, these misconceptions are multiplying even as scientists make unprecedented discoveries in human genetics—findings that, when accurately understood, are powerful evidence against racism. We’ve never had clearer answers about who we are and where we come from, but this knowledge is sorely needed in our casual conversations about race.
How to Argue With a Racist enables us to have responsible, enlightened discourse by illuminating what modern genetics actually can and can’t tell us about human difference. We know now that the racial categories still vexing society do not align with observable genetic differences. In fact, our differences are so minute that, most of all, they serve as evidence of our shared humanity.
