Heritability within groups is uninformative about differences among groups: cases from behavioral, evolutionary, and statistical genetics.

ABSTRACT: Without the ability to control or randomize environments (or genotypes), it is difficult to determine the degree to which observed phenotypic difference between two groups of individuals are due to genetic vs. environmental differences. However, some have suggested that these concerns may be limited to pathological cases, and methods have appeared that seem to give-directly or indirectly-some support to claims that aggregate heritable variation within groups can be related to heritable variation among groups. We consider three families of approaches: the "between-group heritability" sometimes invoked in behavior genetics, the statistic PST used in empirical work in evolutionary quantitative genetics, and methods based on variation in ancestry in an admixed population, used in anthropologic
