Have you met an engineer? I'd say "being an engineer" is probably the single most predictive trait for authoritarianism in my experience.
> According to two European social scientists working in Britain, Italian Diego Gambetta and German Steffen Hertog, who present their case in Engineers of Jihad: The Curious Connection between Violent Extremism and Education, the presence of engineers among known Islamist extremists is 14 times greater than can be explained by random distribution. It was a finding the authors reached with caution and even a certain resistance. “We are social scientists,” Hertog explains in an interview, “so we are always seeking socio-economic explanations. We accepted this idea that there might be personality traits, expressed first in choice of profession and then in political ideology, very reluctantly.”

> This article demonstrates that individuals with an engineering education are three to four times more frequent among violent Islamists worldwide than other degree holders. We then test a number of hypotheses to account for this phenomenon. We argue that a combination of two factors – engineers’ relative deprivation in the Islamic world and mindset – is the most plausible explanation.

If you were to control for other variables I doubt there’d be much correlation. After filtering out engineers who belong to other categories with stronger associations to authoritarianism, you’re more likely to be left with the hyper-individual-freedom types than the hyper-authoritarian types.
And this flows in other areas. If I need a functional vehicle with cheap upkeep I optimize for it. I invest in low risk products since the income is limited. I know that people with plan and confidence are scary, you don’t meet them every day.
It's not really so much one's belief system as it is what happens when one gets power -- and that's hard to predict regardless of the ideology.
This principle of relative consistency is baked into how I test employees for management and friends for trust, and in the past, roommates as well. Though I do acknowledge potential for growth as well, but in my older age I generally also need to see evidence of motivation to give strong benefit of the doubt wrt possible trajectory.
Too often libertarian means liberty for me and not for you. That's authoritarian.
