In the Gilbert & Sullivan operetta Iolanthe, a British Grenadier Guardsman named Sgt. Willis spends a lot of time on sentry duty thinking about the oddities of the universe. During the course of the opera he sings a song in which he shares some of his musings with us and remarks on how tickled he is by the fact
That Nature always does contrive
That every boy and every gal
That’s born into the world alive
Is either a little Liberal
Or else a little Conservative!
Politics is in our genes, Sgt. Willis suggests. It’s inborn.
But that’s just Gilbert being silly, right?
Maybe not.
A new study published in the American Political Science Review argues that, while party affiliation is more determined by the environment in which we are raised, our basic political instincts–conservative or liberal–are influenced by our genes.
The study relies on comparing the view of identical twins raised together to fraternal twins raised together. The results of such a study are suggestive, but not the gold standard of such research. The study was based on comparing twins raised together, but I’d like to see the study controlled by comparison to twins raised apart. If you’ve got two identical twins raised together, there may be additional forces at play that steer the twins toward sharing common opinions on thing besides just their genes. To remove these potential factors from the equation, one would want to look at the views of identical (and fraternal) twins not reared together.
Still, the evidence at hand is worth following up with further study.
The article concludes:
The researchers are not optimistic about the future of bipartisan cooperation or national unity. Because men and women tend to seek mates with a similar ideology, they say, the two gene pools are becoming, if anything, more concentrated, not less.
Okay, so we get culture wars . . . until the Roe effect runs its course and the anti-baby folks breed themselves into cultural obscurity.
