Dem or Repub? Half of the Answer is in Your Genes

A new study from New York University shows that your political preference is more than just a preference: part of it is written in your DNA. “40, perhaps 50 percent of our political beliefs seem to have a basis in genetics,” said Josh Hibbing, political science professor at University of Nebraska, who contributed to the study.

Hibbing’s research showed that identical twins were more likely to share political beliefs than fraternal twins, regardless of how they were raised. But DNA does not “hardwire” the belief itself, it merely affects how a person responds to a given situation. A control-happy neat-freak is far more likely to be a conservative because he or she prefers order and the comfort of the familiar in their life, whereas a touchy-feely, globe-trotting artist is more likely to be a liberal because he or she enjoys new experiences.

But the environment is just a strong a factor as genes, especially when personal security is threatened. Thirty-eight percent World Trade Center survivors, said they grew more conservative after 9/11; only 13 percent said they were more liberal.
