The ## 1## between happiness and technology has been an eternal subject for social critics and ## 2## since the advent of the Industrial Revolution. But it’s been left largely unexamined by economists and social scientists. The ## 3## groundbreaking work on the relationship between prosperity and well-being was done by the economist Richard Easterlin, who in 1969 wrote a famous paper ## 4## “Does Economic Growth Improve the Human Lot?” Easterlin showed that when it came to developed countries, there was no real correlation between a nation’s income level and its citizens’ happiness. Money, Easterlin ## 5## , could not buy happiness—at least not after a certain point. Easterlin showed that though poverty was strongly correlated with ## 6## , once a country was solidly middle-class, getting wealthier did not seem to make its citizens any happier. This seems to be close to a universal phenomenon. In fact, one of happiness scholars’ most important ## 7## is that people ## 8## very quickly to good news. Take lottery winners for example. One famous study showed that although winners were very, very happy when they won, their ## 9## excitement quickly evaporated, and after a while their moods and ##1 0## of well-being were indistinguishable from what they had been before the victory.
