I'm aware of cognitive biases, and know they get me, I just find this use really feeble. Individuals and all that. When I make bad decisions I don't reconcile anything, I swear and grumble and cut my losses and tell myself to forget about it and move on, and sooner or later I usually do forget about it. New day, new situation, new factors, new decisions. New opportunities to make new bad decisions! I'll take a look at that book, thanks.
In very obvious cases, yes, people act like you've described. What this effect manipulates is the judgment of whether something was a bad decision in the first place. People can get disgruntled at a job that is objectively quite good, and can convince themselves that they're satisfied with a situation that's actually not that great.
