Just when we need our entire minds, we seem to be losing them. This is the considered opinion of Johann Hari, a British-Swiss writer and journalist, writing in a Guardian Weekly feature, “Focus (If You Still Can)” (Jan. 7, 2022).

It’s not that we’re losing all our minds, just about 20%, according to studies. This is a critical amount considering that we’re confronting some of the most serious threats to our survival in the history of human civilization, and the capabilities we need to make crucially important decisions are precisely the ones being compromised.
