I happen to actually be a psychology major, in my sophomore year. I’ve heard nothing about this so far in any course I’ve taken. A quick google search I just put in using your suggested line didn’t show any of the results you claim exist either. One thing I did find, from Scientific America, referencing a couple of studies, claims that “Psychologists have found that conservatives are fundamentally more anxious than liberals, which may be why they typically desire stability, structure and clear answers even to complicated questions.“

Also, “Anxiety is an emotion that waxes and wanes in all of us, and as it swings up or down our political views can shift in its wake. When people feel safe and secure, they become more liberal; when they feel threatened, they become more conservative.”

My deepest apologies for not taking exceptional time from my day to find a specific academic journal source. But I’m wondering if you have a reply at least to the above?
