Problem: By default people are group thinkers. That's why we divide ourselves into different groups when talking about politics, religions, ethics. The clearest manifestation of the mechanics of our thinking is when we cheer sports team. If a referee is calling a foul of our player we are highly motivated to examine all the evidence. If out player is fouled we are much more likely to cheer and not be motivated to look into it. This is a confirmation bias that shows up in how we think about:
It's helpful to try be less like soldiers. Trying to win arguments.
And to be more like scouts. Trying to explore the territory. Just see what are the options out there. By the way, people who are able to change their ideas are this predicts a good judgment.
