I always found the appeal to the market gods a bit odd. Why would the market fix mistakes instead of aggravating them?
Because cheating is easier when we can justify our behavior, people often cheat in small amounts: We can come up with an excuse for stealing Post-It notes, but it is much more difficult to come up with an excuse for taking $10,000 from petty cash.
Disasters are usually a good time to re-examine what we've done so far, what mistakes we've made, and what improvements should come next.
What kind of people would be able to rationalize better than other people? Better storytellers, right? Creative people, right? Because if you're creative, you find more ways to cheat and still yourself a story about why this is okay.
It is helpful to think of people as having two fundamental motivations: the desire to see ourselves as honest, good people, and the desire to gain the benefits that come from cheating - on our taxes or on the football field.
Dishonesty is all about the small acts we can take and then think, 'No, this not real cheating.' So if you think that the main mechanism is rationalization, then what you come up with, and that's what we find, is that we're basically trying to balance feeling good about ourselves.
