A paper just published reports that there are: No Genetic Influence for Childhood Behavior Problems From DNA Analysis
This is pretty big.
Using a powerful approach called GCTA, King’s College London researchers Maciej Trzaskowski and colleagues found no evidence that genetics can explain differences in children’s behavioural and conduct difficulties.
This is surprising because these traits are largely heritable – meaning that they run in families, and that identical twins (with all their DNA in common) tend to be more similar than non-identical ones (with only half). But if they’re heritable then, by definition, there must be genes behind that.
But with a few minor exceptions, over a decade of studies drew blanks.
