Even if there is a correlative relationship, there certainly can't be proven a causal relationship. Moreover, I find the possibility of a correlational relationship possible, but not likely given how many other factors are at play here. A system as complex as society has so many variables that to claim one source of anything has a causal effect on anything within that system is just impossible to claim. If I wanted, I could correlate the temperature of Ulan Bator, Mongolia to the price of oranges in Florida. Co-relation is fairly meaningless and causality fairly impossible to establish. Statistics is a very precise machine which one of a thousand things being the slightest bit off will totally and completely break and invalidate the results obtained by utilizing it. If the article's editor can properly explain to me what p-value was utilized to derive significance and explain why the null hypothesis was rejectable and can provide proof of a truly random sample and can explain their experimental design and methodology, then I might - might - see what they have to say. Until then, like so many other "scientific" studies before it, and more yet to be born, right into the trash can it goes.
Exactly.
