Meta-analysis: "60% of the variation in self-control is due to genetic variation between individuals in the population."
A new meta-analysis estimates that the heritability of self-control is 60%.
In a meta-analysis of 31 twin studies with over 33k individuals, self-control was found to be 60% heritable, with no shared environmental influence. The remainder of variance was attributable to non-shared, or individuals' unique environments.
