Genetic defect identified in Leftists
My heading above is tendentious but so are the interpretations offered in the article I am about to discuss
I have been pointing out for years that genetics largely determines politics -- on the basis of twin study evidence. And James Fowler, co-author of the academic article I am talking about, has previously confirmed in 2007 how powerful is the genetic effect on politics revealed in twin studies.
But the mechanism behind the relationship has remained conjectural. The evidence now, however, suggests that there is a gullibility or suggestibility gene -- so people with that gene who also mix a lot with young people tend to adopt the politics of the young. Because they have yet to learn how complex the world really is, young people do tend Left -- the Left being the home of simplistic ideas
The full academic article can be read here or here. The title of the article is "Friendships Moderate an Association between a Dopamine Gene Variant and Political Ideology". Note that this is a study of young adults only so whether the effect lasts into later life remains, again, conjectural. Given the normal movement from Left to Right that most people undergo as they age, the effect of whom you associate with in your youth could well be a transient one
The article also identifies the gene concerned as leading to novelty seeking and my research has shown that Leftists tend to be sensation-seekers. So change for change's sake would seem to be part of what drives Leftism
