Honestly this is a pretty hand-wavy article from a respected journal and I think represents the kind of thing we need less of, not more of His actual research is pretty sparse and comparing the Danish government to every other government glosses over any number of correlation/causation issues. Yet it gets cited and quoted and everyone jumps on it as confirmation of everything they believed before they read it. People need to start questioning the articles that they _agree_ with. If nothing in the article challenges your beliefs, if nothing in the research or conclusions surprise you or makes you consider things differently in any way, than it deserves more skepticism, not less. A whole lot of sites are generating a whole lot of clicks and making a whole lot of money by the simple process of validating their audiences beliefs. It is unimaginably destructive.
