Let's assume that the general education requirements of most college educations (ie, some smattering of English literature & composition, arts, bit of a foreign language, social studies, etc) actually does result in those students coming out slightly more knowledgeable than if they would have had even an "advanced" kind of technical education.
It's a reach, I know, but let's say they are overall a little smarter (ie, learned some new analytical skills & strategies) and are better informed.
I wonder if we're actually better off from this. Not because people aren't smarter or better informed, but because they're only a little smarter and a little better informed and they overestimate how well they informed they are and how good their analytical skills are.
On a mass scale, I wonder how much our political divisiveness and partisanship is driven by a whole bunch of people, who think they're smarter and better informed than they really are, taking sides -- often quite stridently -- on issues they don't really know about and reaching conclusions they don't really have the analytical tools to reach.
Add in the fact that everyone is an Internet Expert on everything they can read in Wikipedia and you have this recipe for high-quality mass ignorance and confirmation bias trying to portray itself as an educated populace.
If we moved the overwhelming majority of these people into a more advanced and focused vocational education that left out the "well rounded" part, would our *actual* ignorance as opposed to overestimated wisdom make us less partisan? Or would we just be even more gullible, swayed by propaganda, etc?
