I'm fascinated (& shocked) by the practice of demanding that people publicly apologize for what they say or write. Sure, a heart-felt apology means a lot. But being made to publicly recant one's honest beliefs is degrading, and to demand this is an act of dominance & cruelty.

Many see bullying, piling-on, and mockery on academic twitter as good people trying to make the world a better place. Others dismiss all of this as "grandstanding" or "virtue signaling". Here's a third explanation: Sadism. People often enjoy humiliating and dominating others.

California just passed a law requiring officers to be screened based on their implicit biases. That's a bad policy. Implicit bias tests aren't diagnostic enough for screening. I study implicit bias & I can't think of a single scientist who'd endorse this.
