Take a local, but vigorously contested, social norm, invent a ‘just so’ story and assert that you have discovered a genetically determined universal.
Gotcha. The daft thing is - I do think human behaviour is influenced by genetic predisposition. I really do. It's just these idiots make it so hard not to snort with derision. Real evolutionary psychology is pretty uncontroversial - by definition. We know shutting someone in solitary confinement is a punishment, we know children like to play with toys, and adults like to gossip about each other. But where's the fun in asserting that?
How much better to 'prove' that the Republicans will always win elections because of the existence of the god gene?
Yes, that's right, there is a simple genetic explanation for universal religious belief. What? You thought religious belief was not universal? You thought religious feeling was a complex of different impulses, which varied massively between individuals and cultures? You thought that attributing religious belief to genetics was demeaning to both religion and atheism? Think again, commie.
Dr. Hamer even identifies a particular gene, VMAT2, that he says may be involved. People with one variant of that gene tend to be more spiritual, he found, and those with another variant to be less so.
That settles it I guess.
