His nickname is the “Indiana Jones of well-being research” because he travels the world and works with exotic groups such as the African Maasai, Greenland Inuit, and Calcutta slum dwellers. To estimate the global level of subjective well-being, Diener aggregated over 900 surveys of 1.1 million people in 45 nations1. On a 10-point scale, where 0 is “very unhappy” and 10 is “very happy,” the average response was 6.75, and the ratings followed a bell-curve distribution. In other words, most people around the world are moderately happy, no matter which country or ethnic group they belong to.
