Is intelligence related to happiness? - PsyPost

What the report says

PsyPost reported on July 19, 2026, that decades of psychology and social science research do not support a simple answer to whether intelligence makes people happier. The article explains that researchers typically assess cognitive ability through standardized measures such as memory, vocabulary, spatial reasoning and math tasks, while happiness is usually measured through life satisfaction and reports of positive and negative emotions.

At the country level, the pattern appears broadly positive. PsyPost cited a 2012 study by Ruut Veenhoven and Yowon Choi using data from 143 nations, which found that countries with higher average cognitive test scores also tended to report higher happiness. The article said researchers interpret this partly through social conditions: populations with greater cognitive resources may be better able to support effective institutions, public safety and economic systems. A 2015 study in Intelligence added that culture matters, with individualistic societies showing a stronger link between national intelligence and happiness.

For individuals, the relationship is less direct. PsyPost noted that Veenhoven and Choi’s review of 23 micro-level studies found no statistical link between a person’s intelligence score and self-reported happiness. A 1998 meta-analysis by Kristina DeNeve and Harris Cooper found intelligence had only a small association with well-being, while traits such as extraversion and emotional stability mattered more.

The article also highlighted research suggesting lower cognitive ability can create practical and mental health vulnerabilities, including studies involving Norwegian conscripts, Dutch twins and English survey data. But PsyPost cautioned that income, health, education, coping skills and social context often mediate these outcomes. Research on Mensa members further suggests very high intelligence may bring its own challenges, especially around meaning and work satisfaction.
