It turns out, feeling powerless boosted the mirror system — people empathized highly.
But, Obhi says, “when people were feeling powerful, the signal wasn’t very high at all.”

“What we’re finding is power diminishes all varieties of empathy,” says Dacher Keltner, a social psychologist at University of California, Berkeley, not involved in the new study.
