The Lancet has been repeatedly exposed as a sham journal with these high-profile studies of high-energy subjects (they are the ones who did the bogus Iraqi civilian death study, where the media further misrepresented the results because J-school doesn’t teach basic statistics).
The problem is that they did away with dispassionate scientific skepticism and replaced it with activist study. As American universities have shown, when you commit to studying socially-aware projects you’ll surely find something to support the outrage.
I know. It's getting harder and harder to trust anything in The Lancet. And the MSM does an atrocious job when it comes to medical reporting, although in general I'd except the WSJ from that criticism.
