Is the IQ of a person with a masters degree in sociology higher than the IQ of a non-degreee naval nuclear power technician? Yet the non-degrees nuke tech would be considered “less educated” by the measures being used in this discussion. A journeyman electrician often doesn’t have a degree, but they do more intellectually challenging work/calculations than some Master of Social Work person working at a local non-profit.
I deal with “highly educated” people in the mental health field on a daily basis and some can barely write grammatically correct sentences: the support tickets I get from people with PhDs and MA mental health professionals are frequently atrocious. But my “uneducated” dad worked as a precision machinist for NASA projects as well as teaching graduate students metallurgy. He’s considered not highly educated, but only because he didn’t get a degree. His education has zero to do with intelligence. That story isn’t an outlier either. My point is that higher education attainment often has nothing to do with intelligence beyond a base level, but more of class, financial resources and desire. A naval fighter pilot with a bachelors degree, in my experience is far more “educated” than someone with a masters in education, sociology, poetry or whatever. Highly educated as a proxy for “desirable worker” is a folly. Ambition, drive and work ethic are more valuable to a society than simply someone who checked the boxes and got a university degree. Using a university degree as a proxy for “desirable” worker is just snobbery and intellectually lazy.
