I don't think there is any general rule, the fact that higher educated elites in the US and western Europe happen to be left leaning is a self-perpetuating accident of history. In many other countries, higher educated elites are right-leaning.

This is an umbrellas make it rain reverse causation. If you look outside the US the education level does correlate with the political spectrum. The higher educated the population the entire spectrum shifts left. See Northern Europe, Japan, Australia, Singapore, China, even political ideology (democracy vs socialism) doesn’t change this correlation

I can tell you that in the former Soviet bloc, higher education correlates very powerfully with leaning right.

I'd bet it's more likely that higher education correlates well with elitism, and that elitism happens to have a left-ish flavor in some countries and a right-ish flavor in others, simply by accident of history, not by some general rule.

I don't see how.

I didn't mention anything about the US, it's a global phenomenon. Personality is a largely biological construct, and it's also highly correlated with political leaning.

Looking at the big 5 model, left leaning people tend to be high in neuroticism(emotional stability) and openness, and low in conscientiousness. Right leaning people tend to be the opposite.

These same traits influence peoples decision to work in academia, openness is a beneficial trait for learning new ideas.

Meanwhile people high in conscientiousness, low in neuroticism are highly sought after in industry.

I’m saying even the right shifts left. It’s not about “left leaning people” it’s the entire spectrum moves. There are still of course right and left leaning people on that spectrum

What I'm saying is that the teachers are left leaning, and it influences their students.

I guess your education did not teach you that correlation does not imply causation. The simpler explanation for why people that are educated lean left is that the people teaching them lean left. Why do teachers lean left? Because they are often broke and underpaid. The fact that there is such uniformity of thought in higher education just goes to show the power of indoctrination.

I feel bad harping on common talking points but most degrees do not teach analytical thought.

I’m talking the whole spectrum, you are caught up on American domestic ideas of left v right.

As my example stated, the far right in Australia would be considered left in the US... the whole spectrum has moved... not talking about individuals... they still exist across that spectrum
