ABSTRACT
We invest much in maximizing intelligence and we get ever smarter: But does this make us any happier? The relation between intelligence and happiness is explored at two levels, at the micro-level of individuals and at the macro-level of nations. At the micro-level, we took stock of the results of 24 studies and found no correlation between IQ and happiness. At the macro level, we assessed the correlation between average IQ and average happiness in 139 nations and found a strong positive relation. Together these findings mean that smartness of all pays more than being smarter than others.
