Quotes:
"The economist J.K. Galbraith once wrote, “Faced with a choice between changing one’s mind and proving there is no need to do so, almost everyone gets busy with the proof.”
Leo Tolstoy was even bolder: “The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him.”
In many circumstances, social connection is actually more helpful to your daily life than understanding the truth of a particular fact or idea. The Harvard psychologist Steven Pinker put it this way, “People are embraced or condemned according to their beliefs, so one function of the mind may be to hold beliefs that bring the belief-holder the greatest number of allies, protectors, or disciples, rather than beliefs that are most likely to be true.”
We don't always believe things because they are correct. Sometimes we believe things because they make us look good to the people we care about.
I thought Kevin Simler put it well when he wrote, “If a brain anticipates that it will be rewarded for adopting a particular belief, it's perfectly happy to do so, and doesn't much care where the reward comes from — whether it's pragmatic (better outcomes resulting from better decisions), social (better treatment from one's peers), or some mix of the two.”
Being part of a tribe or feeling like being a part of a tribe has a huge impact vs feeling at odds with the tribe without a sufficient reward to compensate, it seems.
