Behavioral Genetics

B

Some of my friends think Human Biodiversity is just alt.right propaganda. Others, equally liberal and progressive, think it’s a breath of fresh air in a field overburdened with political correctness. Me, I’m an agnostic. As I often remind people, I didn’t get the True Believer Gene.

With that out of the way, Jayman has what I think is a very nice intro article, “The Five Laws of Behavioral Genetics”. He offers this summary, then goes into a little more detail about each point:

The five laws of behavioral genetics are:

  1. All human behavioral traits are heritable.
  2. The effect of being raised in the same family is smaller than the effect of the genes.
  3. substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or families.
  4. 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.
  5. All phenotypic relationships are to some degree genetically mediated or confounded.

All are simple. All can be said in one sentence. Yet all are incredibly profound and terribly underappreciated in today’s society.

I’m not going to go further than this, at least not today. The article is worth reading if this is a subject that interests you.
