The Five Laws of Behavioral Genetics
The five laws of behavioral genetics are:
For most of the history of the laws, there were only three. The first three were coined by Eric Turkheimer (who has since spent his time trying to undermine his own discovery). Recent genomic studies have added the fourth (Chabris et al, 2015). And Emil Kirkegaard has proposed the fifth based on multivariate behavioral genetic studies. Allow me to review the five laws and their everyday significance.

The Five Laws of Behavioral Genetics
The five laws of behavioral genetics are:
- All human behavioral traits are heritable
- The effect of being raised in the same family is smaller than the effect of the genes.
- A substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or families.
- A typical human behavioral trait is associated with very many genetic variants, each of which accounts for a very small percentage of the behavioral variability.
- All phenotypic relationships are to some degree genetically mediated or confounded.
