Why do people vote the way they do… and believe what they do? A growing number of studies show a link between attitudes linked to heredity and political beliefs. The issue has gotten hot enough that one U.S. congressman spearheaded an amendment to the National Science Foundation budget last May to cut a billion dollars. While the amendment failed, Congressman Jeff Flake’s second amendment to the NSF budget – one that banned any NSF funding of political science research – did pass, because Flake did not want the NSF funding research into the biological roots of political behavior.
According to a recent article in the British New Scientist, “there is a substantial body of data suggesting that conservatives and liberals really are different tribes, divided not by opinions so much as by temperament and even basic biology.” Also interesting is the fact that the article and research were written by Americans and published in a British science magazine. The article itself is comparatively even-handed, pointing out correctly that most research in the field is conducted by liberals and that there are difficulties with some studies. But one of the underlying problems is that, by temperament and biology, the majority of scientists in most fields, excepting those involving engineering and directly related fields, tend to be “liberal” in outlook and politics.
All that said, more than 25 years of study indicate that political attitudes have a high degree of inheritability, and such studies include identical twins raised in totally different environments, who are far more likely to share political attitudes than do fraternal twins or genetically unrelated family members. As a rule, but not invariably, conservatives are more likely to prefer people of their own ethnic background, straight people, and high-status groups. Liberals are more comfortable than conservatives with those of different ethnic and cultural backgrounds, as well as with members of ethnic or sexual minorities. Liberals tend to be more morally offended by inequality, while conservatives tend to be more morally offended by betrayals of the in-group, by disrespect for authority, and by signs of sexual or spiritual weakness or impurity. These characteristics have been linked to anatomical differences in the size of various brain structures. Conservatives have a higher need for certainty, while liberals tend to revel in mental challenges.
In this regard, I’ve always had the feeling that conservatives can’t find the truth because they’ve known it all along, whether it’s true or not, and liberals will never recognize it because they’re so involved in looking for the next thing that they’ll look right past it.
What is clear about all this research is that all of us are biologically inclined in a certain direction in what might be called our social outlook, some more so than others, whether that direction be conservative or liberal. What is also true is that each of us does have the ability to examine those predilections… and to decide whether blindly following our feelings makes sense in any given situation or whether we need to examine what we feel more closely. Obviously, both outlooks are necessary in human society… or those with one inclination or the other would have been weeded out or marginalized, and given the near equal polarization in political outlooks in the United States, that hasn’t happened… and that means, again, blind insistence on doing either just the “conservative” thing or the “liberal” thing is counterproductive. Working out a compromise is necessary.
Unfortunately, I don’t see many signs of this happening in our political situation here in the United States at the moment… and it’s something that needs to occur. As a society, we can’t afford to follow blindly just one of the genetic predilections that evolved to make us successful hunter-gatherers. Nor can we turn our back on what science is revealing about who and what we are. Those are recipes for disaster in a high-tech complex world.
