That's true. But then how do we explain those college undergrads involved in social activism? I don't know exact numbers, but I have a feeling that the average college undergraduate's IQ isn't so deflated that her reading comprehension is compromised...?
Well to your prior point about the relatively small number of college undergraduates doing the sort of extreme political activism like those interviewed, it's obviously not a problem with the average undergraduate. The constant pushing of everyone towards post-secondary education, and the plethora of grants, loans, and scholarships, plus reduced academic standards (compared to what someone like me would find ideal), plus AA type programs, all work towards allowing people in that cannot function well in an academic environment for any number of reasons.
When someone is in an environment where they are overwhelmed, they can respond in a variety of ways. I saw a relatively normal looking kid become a shell of himself after 2-3 weeks of bootcamp: bedwetting, open sores, practically catatonic at certain times (obviously he was sent home). He was an outlier of course (no one else out of the ~60 of us was sent home for "failure to adapt"), and in an environment where although overwhelmed, everything was extremely controlled.
For someone of average intelligence and a substandard cultural background, being thrown into the high pressure/gentrified nature of academia + hearing language about oppression + being away from home/low supervision + any other number of other radical life changes, this could lead to other sorts of acting out. Self harm, protesting, vandalism, etc.
I would agree that significant differences exists between those with drastically different IQs, but I guess I'm hesitant to blame reading comprehension for the current practices/beliefs of social activism. Those who are uneducated and non-academic probably aren't even visiting the wikipedia pages for the kinds of theorists we're talking about, and those who have cause to (i.e. your average Humanities undergrad) most likely have the intelligence and supporting structures in place necessary to comprehend the material. So I think that more often it comes down to either complete unfamiliarity or an unwillingness to put in the time/effort to understand.
If the common college protester superimposes a set of progressivist values over theoretical materials and appeals to this as justification, I would be less inclined to blame reading comprehension than simple laziness.
Well you asked how science tests this. I listed the two most relevant tests I could think of. Unfortunately the kind of specific tests one would need to run to sort of answer these questions would probably never get funding.
I also think you're a "victim" of the Dunning-Kruger effect on this, as are many intelligent people (including myself until hearing about it/experiences in the last few years). Even if reading comprehension isn't an issue (that is, one can read the words and understand the literal definitions), this doesn't mean one can fully grasp theories. Studies are somewhat limited, but there is some evidence that general intelligence/IQ cannot be thought of as existing on a smooth continuum. Rather it is more stair-stepped, and that there may be certain thresholds required, (or maybe certain genes switched on or whatever), for a person to be able to understand or perform at "the next level". As far as I've been able to determine, an IQ of 120 is a supported threshold. After that, differences are almost entirely about hard work/study/etc. 120 is also firmly +1SD on the distribution curve, with only ~20% of the population holding that IQ or higher. Recent percentages of 18-24 year olds in the US enrolled in some sort of post-secondary education was ~40%. That's large difference.
As far as laziness or unwillingness go, it's hard in many cases to tease apart incompetence and indolence. A complete or at least general lack of interest in serious/certain topics is a sign of the inability to actually deal in them satisfactorily (of course this isn't some sort of foolproof test).
