Correlation can tell us where to search, but the article concludes with the author being smug about sprinkling chili onto his omelette. There are still plenty of confounding factors, hardest of which to control for post-hoc would be self selection bias. This study just takes the data from a prior study and analyzed to see if one of the specific variables would predict another. There's no way to tell if they just did this for all of the variables, if they did this without having a prior hypothesis then the results should only be used for constructing another study, not as interpretable results that we can take action on.
