More on irrational behavior from a famous economist: losses loom larger than gains, that first impressions shape subsequent judgments, that vivid examples carry more weight in decision making than more abstract � but more accurate � information, the phenomenon of loss aversion (people don't like losing), and although divorced women are are less satisfied with their lives than married women, they're actually more cheerful, and finally, people are really happier with friends than they are with their families or their spouse or their child. (Most people. That's not true of me.)
