I think it is trained into us in school where kids are given lots of praise and recognition for providing answers, and kids who stop to think are laughed at.
Also in our media, someone who knows what they’re doing is presented as confident and quick in their responses. We don’t have any images of people saying “Well I’m not sure” and then later being the heroes.
Wisdom is always portrayed as immediately knowing exactly what to do.
I’m hoping that with all the negatives, at least WW3 will force our culture to adopt a more workable model of decision making given our decisions will now be life or death decisions.
