From The Boston Globe:
In recent years, cognitive scientists have turned in increasing numbers to the study of human happiness, and one of their central findings is that we are not very good at predicting how happy or unhappy something will make us. Given time, survivors of tragedies and traumas report themselves nearly as happy as they were before, and people who win the lottery or achieve lifelong dreams don't see any long-term increase in happiness. By contrast, annoyances like noise or chronic pain bring down our happiness more than you'd think, and having friends or an extra hour of sleep every night can raise it dramatically.
These findings have fed the growth of a burgeoning “positive psychology” movement focused on helping people enrich their own lives. But now some scholars are starting to ask a bigger question: shouldn't this new understanding affect policy, too? A huge range of social systems, from tort law to urban planning to medical care, are built on assumptions about what makes people happy. Now, for the first time, researchers are claiming to be actually measuring happiness, to actually know what causes it. In a society whose founding document asserts a basic right to the pursuit of happiness, that new knowledge could have far-reaching implications.
