Research [Country roads, take me home… to my friends: How intelligence, population density, and friendship affect modern happiness] by SMU Associate Professor of Psychology Norman Li and his collaborator revealed that more intelligent individuals experience lower life satisfaction with more frequent socialisation with friends. They believed that this can be explained by “the savannah theory of happiness”. The data was garnered from two studies based on a massive national review of over 15,000 people between the ages of 18 and 28. The first study examined the link between subjects’ scores on an intelligence test, the population density in the area where subjects lived, and how satisfied subjects reported feeling with their lives. The second study evaluated how subjects’ IQ scores compared to their life satisfaction and how often they socialised with friends.
