We have very strong intuitions about all kinds of things — our own ability, how the economy works, how we should pay school teachers. But unless we start testing those intuitions, we’re not going to do better.

While we somehow understand revenge on an intuitive level between individuals, I do suspect that companies, assuming that people are rational, completely miss and underestimate the motivation people have for revenge.

The experiments show quite clearly that, as you resist more and more temptation, you're actually more and more likely to fail.

The things that motivate us are to help other people, to feel that we're useful, to feel that we're getting better, to feel that we are kind of living to our potential, to get a sense of meaning. All of those things are positive.
