Unexpectedly, we found positive genetic correlations between AUDIT and years of education, college attainment and childhood IQ. This association was suggestive for the within-sample phenotypic correlation (Supplementary Table 5) and was significant for the genetic correlation (Supplementary Table 9). Consistent with this finding, Clarke et al (2017) reported that college attainment and years of education were positively genetically correlated with alcohol consumption in females but not males.
