Specific Gene — And Adolescent Popularity — Determine Liberal Leanings
October 28, 2010
(ChattahBox Science News) — Some people say that their political opinions are “part of their DNA.” Now, scientists have determined that might actually be accurate, NBC San Diego reports.
Researchers with UC San Diego and Harvard University determined that a gene called “DRD4”gives people a genetic predisposition to have liberal political leanings. However, the gene alone does not create liberals – it has to be coupled with adolescent popularity. “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,” the study notes.
To reach their conclusions, the scientists evaluated 2,000 subjects, and their findings were not dependent on ethnicity, sex, age, or culture of the subjects, NBC San Diego reports.
