Generally speaking, a criticism of a study that focuses only on something like this is uninteresting -- while it _may_ be a valid criticism, it is not always (many valid studies have very small samples!), and so stating it unsupported is actually more like evidence that you don't know how to critically evaluate a study. As Zeynep Tufekci said: 'Anybody immediately responds to a correlation with “but correlation does not imply causation” probably doesn’t know what they’re talking about. Don’t have much to say, throw around smart sounding cocktail phrase.'
