Individuals with high IQs are more likely to say they're happy than peers with lowers IQs, according to a study in Psychological Medicine.
To assess the relationship between intelligence and happiness, University College London researchers examined data on 6,870 individuals from England's Adult Psychiatric Morbidity Survey. They noted that individuals with lower IQs often had lower incomes and poorer health, factors that can contribute to unhappiness.
The study found that 43% of individuals with an IQ between 120 and 129 reported feeling "very happy," more than any other IQ group. Meanwhile, 12% of individuals with an IQ between 70 and 79 reported feeling "not too happy," more than any other IQ group.
"There is some evidence that long-term intensive strategies directed at young children from socially deprived backgrounds can have a positive impact not only on IQ, but also on wellbeing and life opportunities," lead author Angela Hassiotis says. She added that costs for such interventions could be "offset by future benefits such as a reduced reliance on state benefits and better mental and physical health" (BBC News, 9/26).
