““How’s this for fascinating: Heritability of various aspects of cognitive development is very high (e.g., around 70 percent for IQ) in kids from high–socioeconomic status (SES) families but is only around 10 percent in low-SES kids. Thus, higher SES allows the full range of genetic influences on cognition to flourish, whereas lower-SES settings restrict them. In other words, genes are nearly irrelevant to cognitive development if you’re growing up in awful poverty—poverty’s adverse effects trump the genetics.fn24 Similarly, heritability of alcohol use is lower among religious than nonreligious subjects—i.e., your genes don’t matter much if you’re in a religious environment that condemns drinking. Domains like these showcase the potential power of classical behavior genetics.””
