Parents’ polygenic scores for educational attainment predicted their warm, sensitive, stimulating caregiving over and above the quality of their own experienced-parenting.

Note: Scatterplots depicting the association between parents’ polygenic scores (z-scores) and an overall measure of warm, sensitive, stimulating caregiving (z-score), separately for participants within the bottom, middle and top tertile for own experienced-parenting (a categorized version of the continuous measure of own experienced-parenting used in the analyses). Each plotted point represents the mean x and y coordinates for a bin of about 5 parents. The solid red line is the best-fitting regression line. The dashed lines show the mean level of warm, sensitive, stimulating caregiving for each subgroup. The polygenic score tended to predict own parenting better among people who had experienced more negative parenting in their family of origin (left panel above), however this association was not statistically significant with our sample size (p-value for the interaction was p=.06).
