Conservatives Big on Fear, Brain Study Finds
https://www.psychologytoday.com/blog/the-human-beast/201104/conservatives-big-fear-brain-study-finds
Peering inside the brain with MRI scans, researchers at University College London found that self-described conservative students had a larger amygdala (link is external) than liberals. The amygdala is an almond-shaped structure deep in the brain that is active during states of fear and anxiety. Liberals had more gray matter at least in the anterior cingulate cortex, a region of the brain that helps people cope with complexity.
Students as a group are younger people who generally don't yet know much about life. Many of them may be great at academics... I was much better at science, advanced math, history, and other academic theory than I am now - but I now am infinitely smarter than I was 25-30 years ago. And balancing equations or teaching economic theory for a living doesn't pay nearly as much as what I've learned AFTER college pays me personally.
I am far more fiscally and economically conservative in middle age than I was in my teens and early twenties - free college and healtcare, a higher min wage, more and stronger unions, etc would have sounded great to me as a college student and grocery store employee when I was 18-21.
I also have an appreciation for the US military and national defense matters that I did not have at 18-21.
Yet I am more tolerant and respectful of gays, immigrants, etc than I was 30 years ago - more socially "liberal" in some ways.
"Most societies are divided into a party that wants change (the more liberal party) and one that is afraid of change (the conservatives). The liberal party is generally more intellectual and the conservative party is more anti-intellectual."
By this definition, I would have been considered liberal during Obama's 2 terms. This clown offers zero proof for his assertion that a "liberal party" is more intellectual than a "conservative party", and only makes himself look like the sheltered psychology PhD he is.
I am far more "liberal" socially and in other ways than my father and grandfathers were, and they were diehard southern blue collar union democrats. I am more fiscally and economically conservative than they were - they didn't understand that overpaying workers could be a bad thing, for example.

The author of your article may not even aware that when the country was founded, the one function of the federal government was to provide a national defense. And he probably believes that if we were just nicer and more submissive to the Bin Ladens, Putins, and Kim Jongs of the world that we would have no need for a military.
He seems to equate intellect with the desire for more government involvement domestically and in our lives in general. He probably believes that if we simply ban all guns that the gun violence (and violence in general) that mostly occurs in certain areas of a few large US cities would virtually cease to exist.
Fear is an essential element for survival and success for most of us. A tenured, sheltered, left-leaning PhD teaching and living in a nice suburb or rural small town probably doesn't have much to fear in his little world.
I am pretty active in my alumni association, and have had many friends and acquaintances who have earned similar educations to that author, and most of them tend to be very sheltered and ignorant about many things outside of the theories they teach from their textbooks. Professors in engineering, business and related fields, mathematics and applied sciences, and even criminal justice tend to have much more horse sense and tend to be much more well-rounded people.
