I personally find a lot of the material about cognitive biases hard to swallow -- I was forcing myself really hard when I read Kahneman's book. There were some good points but while reading it something just seemed off in a way similar to trying to break down the world into a rigid dichotomy -- likes "is the a ok approximate anwser?" "Yes" "Would I use it?" "Possibly with great skeptism and appropriate weight given the context, but likely not"
