> IMO "common sense" is very much a trap-concept. It's how we usually convince ourselves that our preconceived ideas are right.
To add more to this, I would argue that our tendency to oversimplify subjects is a large part of many of the issues we face today. Important to remember that first principle reasoning is not the same as first order thinking. Most of the problems we face today are deceptively complex (appear simple on the surface but aren't) and first order approximations aren't good enough and can actually lead you away from a solution rather than towards. First principle thinking does require you to reevaluate your assumptions as well as constantly having serious doubt (challenging your own ideas).
