In the last week, I’ve blocked acquaintances on Facebook for posting conspiracy theories and nasty responses to innocuous political commentary. I’ve been disappointed to find friends enamored with miracle treatments and proclamations of existing herd immunity. Other people I know have shown unexpectedly ugly sides of their personalities — prejudices, a disdain for expertise and science, cognitive biases — which make it difficult for me to continue my relationships with them.
My sudden willingness to cut people off if they won't change their minds is unusual. I've been a psychologist for 25 years and, though it was an initially challenging concept for me to accept, I do know that some people are incapable of change.
