Genetics Accounts for a Lot of Behaviour, Which Should Inform Public Policy Moving Forward

What? recent meta-analysis of 2748 twin studies showed that genetic impacts on outcomes like diet, political attitudes, and conduct disorders are 1 to 10 times larger than the influence of shared environment, such as parenting. This suggests that some social science research may be overstated, as it does not account for the effects of genetics.

So what? It is important to know to what extent behavioural outcomes can be externally shaped. In an age of cheap genetic testing, it may be useful to conduct social science studies using genetics as an explicit variable, given that the role of genetics in shaping behavior could inform public policy.
