As an engineer, I do think there’s some mild but noticeable correlation in bulk. But there are other categories which would be much more predictive. And most of the correlation with engineers are actually a confounder effect from things like multigenerational socioeconomic status, or religion.

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.

I am electrical engineer and electrician working in regulated areas. In both areas the frameworks limits my choices and obviously I am very authoritarian. There is no room for discussion. If I need a DC DC converter for 2 amps I will pick one rated for 4 amps. No discussions! If I need to install a heat pump 60 feet away I will pick 5x6 square millimeter cable and all the circuit breakers from installation manual. There are no options or opinions. I communicate this in polite way to the clients.

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.

Possibly, but it's just as much a predictive trait of being libertarian, which for all its faults, is extremely anti-authoritarian.
