I have come to believe that almost all of our social pathologies stem from two deeply-ingrained tendencies: 

1. People care more about belonging to the Inner Ring than about telling the truth. Indeed, in many cases lying for the Ingroup is the best means of demonstrating one’s commitment to it. 
2. People are presentists not just in the sense I often talk about — attending only to the stimuli the dominant media offer now — but in the sense of doing whatever offers immediate gratification and leaving the future to care for itself.  

Anyone who cares about the flourishing of our social order and of the planet needs to think about how to chip away at these tendencies — and I think “chipping away” is the best we can do. A while back I was on a Zoom call with Jonathan Haidt, and I asked him whether he thought that seeing and acknowledging the truth about one’s condition might be an evolutionarily adaptive trait. He replied that beyond some fairly low-level lizard-brain things — like seeing that that really is a bear charging at you and you had therefore better take evasive action — he thought not. For human beings, the ability to belong is more adaptive than the ability to see what’s true. 

So: these are incredibly powerful forces; none of us will ever be completely free from them, and some of us will be prisoners of them all our lives long; but their hold can be weakened, and I think constantly about how to do that — for myself first, and for others later.
