Confidence is defined as our degree of belief that a certain thought or action is correct. There is confidence in your own individual decisions or perceptions and then the between person confidence where you defer your own decision making to someone else.
Why am I thinking of confidence? An article by Cass Sunstein explains it well. The article appeared in Bloomberg, Politics & Policy, October 18, 2018, Bloomberg Opinion, “Donald Trump is Amazing. Here’s the Science to Prove It.”
Cass Sunstein is one of the more accomplished writers on judgment and decision making. He is an attorney and was recently the head of OIRA, the Office of Information and Regulatory Affairs at the White House. He seems to be able to write a book in about a day. He has written about twenty books including Nudge with Richard Thaler. One of the reasons is that the books each overlap a good deal, which should make it easier for me to get the gist of his ideology. Ken Hammond wrote of him as one of the coherence school of judgment and decision making.
He often speaks of conformity, social cascades, and group polarization. Group polarization seems to me to relate to the ideas of supersense, sacred values, and moral imagination that were presented in my previous post. I enjoy his references to the founding fathers and these references are often the most persuasive part of his work. This post looks at the two books referred to in the title of the post. The post will not be a good summary, but includes a few things I found interesting.
