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.
