Well, I didn't mean your comment was a case of naivete, because, TBH, the analogy with my layman physics example isn't perfect, but it reminded me, it's a similar thing: people who are or should be aware that they have only superficial info on something, act as though what they know is all there is to it. The point is, we can't possibly come up with a meaningful critique of this research based on the given article, and, I think, the most reasonable course of action in this particular case is to assume the researchers know what they're doing (considering who's involved).
