This is not "real" science. It is "pop" science. I always like articles that include something like the following: "Scientists now think..."
Because it is not as if this study would be generally accepted by most scientists as indicative of anything. Certainly not objective, reproducible results. Spurious results? Small sample size? Pre-selected sample subjects, not randomly tested? Etc.
In fact, I seriously doubt the actual study came to ANY conclusion at all. Probably said "worthy of further research" or something similar.
But we all know reporting that would not get any readers or viewers, would it?
