One of the masterminds I participate in is a WhatsApp chat group that we’ve labeled Juxtaposed Jedi. It’s a daily chat with three of us, where we’re bouncing ideas off each other, conducting thought experiments, and getting and giving advice. One of the most valuable parts of the process is when we point out faulty thinking. This could be a confirmation bias someone has, making an assumption from a bad premise, emotional irrationality, or simply sloppy logic.
