A lot of DUmmies carry around stacks of raw data with them - facts, figures, dates, names, etc. - which they can whip out at a moments notice. The problem is, they don't contextualize well. They don't know how to synthesize that data into a coherent whole. There's never a gestalt moment where all the pieces fall into place, "the penny drops" so to speak, and they reach a natural realization of the truth. That's why their arguments for the most part are circular. "It is, just because, well, it is." When faced with rigorous analysis, they become confused, angry, and slip into ad hominems and argument from emotion.
Look at videos of confrontations of conservatives versus liberals in, say, street protests. The conservative remains cool, calm, and presses their argument, while the liberal has devolved into a shrieking, epithet-spewing creature of stimulus/response. They have fragile egos that melt down when challenged or cornered. They refuse to subscribe to the notion of past performance or behavior being the single greatest predictor of future performance or behavior. Hence, the steadfast insistence that Socialism and Communism can work, despite the dismal failures of its past, if only it was "done right". The danger lies in what else is ignored - that those failed experiments in social engineering resulted in the loss of tens of millions of lives.
So I would say that a great many of them have the capacity to accumulate knowledge, and the cunning to wield it like a blunt instrument on the unsuspecting. But in-depth reasoning? Not so much. And wisdom is right out.
