Individuals carrying a particular variant of the D4 gene affecting the neurotransmitter dopamine are more likely to turn out to be liberals, conclude researchers from the University of California, San Diego, and Harvard University.
This gene variation has already been linked to a personality type driven to seek out new experiences.
To see if this predisposition also fed through into political beliefs, the researchers looked at 2,574 participants in the National Longitudinal Study of Adolescent Health to find out about their political behavior, civic activity and social networks.
“Ten friends can move a person with two copies of the 7R [variant] almost halfway from being conservative to moderate or from being moderate to liberal,” the study concludes.
Its authors don’t draw the other obvious inference of their research: that liberals are likely to have more friends than conservatives.
As the midterms draw near, liberal America needs all the friends it can get.

A gene for liberalism? :shk:
Somehow, I don’t think nature selects for political affiliation.
Nor do I believe that liberalism is simply the byproduct of a genetically-determined hedonic tendency and sociability, as this seems to imply.
I am greatly persuaded by evolutionary psychology, but I don’t think this particular ‘finding’ is at all trustworthy. It’s either very bad science, or good science misinterpreted and blown out of all proportion by a journalist.
In fact I think science itself is very bad.
I really don't find the results extraordinary or even hard to believe.
Star for you anyway.
