“Educated” does not equal intelligent, and it certainly does not imply broad intelligence. You can train a relatively stupid human being to do all kinds of stuff and if you’ve ever worked with people with degrees you know what little value they carry.

I went to college and have white collar career and my family is largely university educated. I worked with structural engineers at my last job and half them were just barely able to do their jobs with the worst ones being the senior people. Elsewhere in the world there have been anti-vax doctors and nurses, psychotic therapists, and theologians who have read the bible who still do all the horrible things they definitely know are bullshit. I bet nearly half the people here on Lemmy know a software developer or three who shouldn’t ever touch a computer. People with degrees are more likely to be more intelligent but, especially while living in a world where they’re basically expected, that’s really just not a guarantee.
