Hey Midius!

My recommended rationality habit is noticing confusion, by which I mean a specific mental feeling that's usually quick & subtle & easy to ignore.

David Chapman has a more wooey version called Eating Your Shadow, which was very helpful for me since it pointed me towards acknowledging parts of my experience that I was denying due to identity & social reasons (hence the easy to ignore part).

I tried to read thinking fast and slow and then just skipped to the papers in the appendix and my impression is that was more compressed and efficient. Also I recommend “rational choice in an uncertain world.”

I recommend Algorithms to Live By
