What It Is
Judgement is about making good decisions.
Real decision-making is rapid, biased, and subconscious. And we rationalise our decisions after the fact. Having good judgement mostly concerns fixing (or not repeating) bad decisions.
More than IQ.
It’s clear that some people have better judgement than others. But what sets them apart? Although most people would say intelligence, that doesn’t account for the abundance of very smart people who continually make very bad decisions.
