There is a field of study called “happiness research,” which tries to analyze what makes people happy. Prof. Michael Hagerty of the University of California at Davis surveyed decades of international happiness research and found that “for the most part, the top-rated countries are small and homogeneous.” As he explained, such countries “have a similar world view and a similar religion, so that it’s easier for them to communicate and to understand each other’s motives.” He also noted that “they don’t have race problems.” In the conclusion of his 148-country diversity survey Tatu Vanhanen wrote, “It is easier to establish harmonious social relations in ethnically homogeneous societies than in ethnically divided ones because people are more helpful towards each other in ethnically homogeneous societies.” There can, of course, be many different kinds of division in a country: language, religion, race, class, etc. However, of all these, race seems to be the most difficult to bridge.
