Significant differences between genetic correlations indicated that, the genetic variants associated with income are related to better mental health than those linked to educational attainment (another commonly-used marker of SEP). Finally, we were able to predict 2.5% of income differences using genetic data alone in an independent sample. These results are important for understanding the observed socioeconomic inequalities in Great Britain today.
Educational attainment shows a larger genetic overlap with subjective wellbeing than IQ does (rgs = .11 & .03, respectively), while income shows a larger genetic overlap with subjective wellbeing than both education or IQ (rg = .32).
