"As predicted by the theory, population density is negatively, and frequency of socialization with friends is positively, associated with life satisfaction. More importantly, the main associations of life satisfaction with population density and socialization with friends significantly interact with intelligence, and, in the latter case, the main association is reversed among the extremely intelligent. More intelligent individuals experience lower life satisfaction with more frequent socialization with friends." The Abstract section
The study was written by researchers Norman P. Li and Satoshi Kanazawa. Li and Kanazawa used the 'Savanna principle' to distinguish and isolate modern social influences. Kanazawa coined the term in 2004, it compares ancestral methods and behaviors to modern ones.
15,000 participants, aged 18-28 were surveyed. The data makes sense across the board, until you factor in intelligence. It would stand to reason that intelligent people would value the time they spend with friends and family.
Our lives are brief and every moment is a gift. The more experiences we have with our inner circle, the more enriched our life is. Carol Graham, another researcher, offers an explanation:
'Those with more intelligence and the capacity to use it … are less likely to spend so much time socializing because they are focused on some other longer term objective."
Intelligence in relation to happiness, evolved to handle and solve 'novel' evolutionary problems. These problems affect survival or reproduction. The are 'novel' in that they are anomalous and don't re-occur.
"More intelligent individuals, who possess higher levels of general intelligence and thus greater ability to solve evolutionarily novel problems, may face less difficulty in comprehending and dealing with evolutionarily novel entities and situations," Li and Kanazawa
Intelligent people see different novel evolutionary problems, and spend their time trying to solve it. They are quicker than less intelligent people to abandon pre held social structures in pursuit of their goals.
"Even though our empirical analyses ... used a measure of global life satisfaction, the savanna theory of happiness is not committed to any particular definition and is compatible with any reasonable conception of happiness, subjective well-being, and life satisfaction," Li and Kanazawa.
