In a 2024 episode of 10% Happier, host Dan Harris spoke with Stanford psychologist Claude M. Steele about a phenomenon he calls "churn"—the background hum of worry that arises when people interact across lines of difference. Steele argues that this tension is not primarily about prejudice or bias, but about a rational fear of being seen through the lens of a negative stereotype in a situation that matters.
