This study investigates the causal relationships between educational attainment, intelligence, and wellbeing using genetic and observational data. Mendelian randomization analysis revealed a positive causal effect of educational attainment on wellbeing, independent of intelligence, and a negative effect of intelligence independent of educational attainment. Observational analyses suggested sex differences in these associations, with greater wellbeing benefits from higher education for females compared to males. The findings highlight the unique contribution of education to wellbeing beyond cognitive abilities.
