1) Post from the past:The biological bases of behavioral variation. 2) Weird search query of the week: "clothedpornstars." OK, so now I know what this is. But are there stars in this kink-genre? 3) Comment of the week, in response to "Does heritability of political orientation matter?":

” This is why heritabilities of being conservative and liberal can remain the same over time and across cultures, even though conservative and liberal can mean very different things in different contexts.” Possibly, but there’s a physiological basis underlying the liberal/conservative bias. The latter has been traced to differencies in dopamine neurotransmitter chemistry which are innate to the individual: This does not change with external circumstance. Accordingly, Liberals are feelings-driven and respond to political issues emotionally. They cherry-pick facts that support their pre-conceived conclusion. Conservatives are logic-driven, weigh all the facts and reason sequentially to a conclusion. Liberals cherish security; Conservatives cherish liberty. All else stems from those values.
