I have heard employers and managers commonly remark that "so and so doesn't have the DNA for this job." It's well-known by now that many, if not most, temperaments, talents, personality traits and tendencies have a genetic foundation. With overdetermined things like political attitudes, one might expect those foundations to be obscured by life experience, education, and personal growth.
But they aren't, entirely. Wilson discusses in City Journal. A side point he makes, which I feel is well-taken, in reference to Adorno's famous study of the authoritarian personality and Bouchard's further work on the topic. He says:
In his study of identical twins reared apart, Bouchard concludes that right-wing authoritarianism is, to a large degree, inherited—but he says nothing about the Left. This omission is puzzling, since as Bouchard was studying twins at the University of Minnesota, he was regularly attacked by left-wing students outraged by the idea that any traits might be inherited. A few students even threatened to kill him. When I pointed this out to him, he suggested, in good humor, that I was a troublemaker.
Yet if you ask who in this country has prevented people from speaking on college campuses, it is overwhelmingly leftists. If you ask who storms the streets and shatters the windows of Starbucks coffee shops to protest the World Trade Organization, it is overwhelmingly leftists. If you ask who produces campus codes that infringe on free speech, it is overwhelmingly leftists. If you ask who invaded the classroom of my late colleague Richard Herrnstein and tried to prevent him from teaching, it was overwhelmingly leftists.
He gets it. I never understood the equation of "Right" with Libertarian/Conservatism either. His essay, The DNA of Politics, here.
It is curious how Darwin, evolution, and inheritance is ignored by the rabid Lefties. Unless God is involved. The wacko Left is ever on the march.
