People in general (at least on da Internetz) seem to focus way to much on single studies, and way too little on meta-studies. AFAICT meta-studies is the level where we as a society really can try to say something intelligent about how stuff works. If an important question is not included in a meta-study, we (i.e. universities and research labs) probably need to do more research on that topic before we really can say that much about it.
