Gene for Liberalism Identified
Well, this explains a lot:
The study was led by UCSD’s James Fowler and focused on 2,000 subjects from the National Longitudinal Study of Adolescent Health. Scientists matched the subjects’ genetic information with “maps” of their social networks. According to researchers, they determined that people “with a specific variant of the DRD4 gene were more likely to be liberal as adults.” However, the, subjects were only more likely to have leanings to the left if they were also socially active during adolescence.
“It is the crucial interaction of two factors — the genetic predisposition and the environmental condition of having many friends in adolescence — that is associated with being more liberal,” according to the study.
