My most favorite psychological insight.
Your health care adviser, Zeke Emanuel, advised you to hire a proper engineering manager to oversee the development of this massive technical project. Your team of economic advisers gave you that advice as well. You chose to ignore them and appointed a policy wonk to that position. But I forgot—you've said in the past that you are a better speechwriter than your speechwriters, and you know more about policies on any particular issue than your policy directors. So it makes sense that you would ignore the advice of the people you hired to advise you. You are a perfect example of the Dunning-Kruger effect.//
