  It's weird how there's a whole thriving genre of studies that look at things with incredibly complicated causal graphs, maybe control for a random smattering of confounding variables, find a correlation between some variables X and Y, and then declare victory -- even though what they found is seldom an actual causal relationship between X and Y, both in theory and in practice [1].
