Misguided model of human behavior: Comment on C. H. Burt: "Challenging the utility of polygenic scores for social science…"

Abstract

This commentary emphasizes two problem areas mentioned by Burt. First, that within-family designs do not eradicate stratification confounds. Second, that the linear/additive model of genetic causes of form and variation is not supported by recent progress in molecular biology. It concludes with an appeal for a (biologically and psychologically) more realistic model of such causes.
