I'm about halfway through doing just that and I think a pattern has emerged: does there exists a plausible, concrete (you could put it into words) mechanism for cause and effect? That is, can a person tell you why the finding exists. For instance, a semantic association between capitalism and greed does not provide a plausible mechanism for why mentioning capitalism should make one greedy. The gay one failed that test, but otherwise that seems to be what's going on. A lot of these papers aren't testing a scientific theory. They're testing vague, half-baked ideas and associations.
