Humans should adopt a model of argument based on the exchange of information to converge on truth rather than treating argument as a competitive war.

“Instead of two people beating each other up and the one left standing wins, that's not how you discover the truth. Or even bargaining and negotiating and you come to some compromise. You think about why should the truth just happen to lie halfway in between two opinionated guys?”

Humans are naturally prone to 'resulting,' a heuristic that incorrectly judges the quality of a decision based solely on the outcome.

“we have this simplifier the shortcut called resulting so what we do is we say if I know what the quality of the outcome is I can work backwards from that to the quality of the decision”

Being in a state of flow while engaged in challenging tasks is a significant source of happiness.

“one of the coolest concepts in positive psychology is this concept of flow this time when you're kind of so entrenched in something that you're like losing track of time”
