A study led by James Fowler , according to scientists at UC San Diego and Harvard University, shows that liberalism is determined by social activity during adolescence + DRD4, a dopamine receptor gene. The researchers determined that people "with a specific variant of the DRD4 gene were more likely to be liberal as adults." A pill to cure or enhance liberalism may be on the way.
go home from us in peace. We seek not your counsel or your arms. Crouch down and lick the hand that feeds you;
may your chains set lightly upon you, and may posterity forget that ye were our countrymen!"
