I was thinking about this as a problem of so-called social epistemology -specifically, of what a person ought to believe when her or his beliefs contradict someone else's. It seems obvious to me that -other things being equal- the rational approach to take when encountering someone who appears rational and well-informed and who disagrees with you, is to take seriously that person's thoughts. Since the abstract authors fit the description, it's obvious, I think, that what they say deserves at least some consideration -ie, what they say is not obviously worthless (ie., to be dismissed with a one liner).

Is this fair?

I realize the situation is more complicated here, as there's the question whether a whole discipline has gone off the rails, which I think the OP has convinced himself is the case with philosophy (so, maybe other things aren't equal). I've tried a few times without success to recommend some epistemic humility on this point.
