Social science genetics is concerned with understanding whether, how and why genetic
differences between human beings are linked to differences in behaviours and socioeconomic …

Genetic correlations estimated from genome-wide association studies (GWASs) reveal
pervasive pleiotropy across a wide variety of phenotypes. We introduce genomic structural …

In a replication of Turkheimer, Haley, Waldron, D’Onofrio, Gottesman II (2003, Socioeconomic
status modifies heritability of IQ in young children. Psychological Science, 14:623-628), we …

Behavior genetics studies how genetic differences among people contribute to differences
in their psychology and behavior. Here, I describe how the conclusions and methods of …

Behaviors and disorders related to self-regulation, such as substance use, antisocial behavior
and attention-deficit/hyperactivity disorder, are collectively referred to as externalizing and …

Consistent with social neuroscience perspectives on adolescent development, previous
cross-sectional research has found diverging mean age-related trends for sensation seeking …

Genes account for between approximately 50% and 70% of the variation in cognition at the
population level. However, population-level estimates of heritability potentially mask marked …

I find the use of a correlation coefficient a dangerous symptom. It is an enemy of generalization,
a focuser on the “here and now” to the exclusion of the “there and then.” Any influence …

There are dramatic individual differences among adolescents in how and when they become
sexually active adults, and early sexual activity is frequently cited as a cause of concern for …

Estimates from genome-wide association studies (GWAS) of unrelated individuals capture
effects of inherited variation (direct effects), demography (population stratification, assortative …
