Look up Hbomberguy's video on the matter. It was the lancet, but it was an erroneous publication. Rare, but it happens. The study was grade A bullshit.

What is the blame we should place on them? The whole point of science is that shitty theories and great theories live in the same space. They're then evaluated by the collective body of scientists based upon the results of their tests. Eventually the shitty hypotheses dies off. No one is ever supposed to rely upon one study or even a few studies. It should take years and many studies before the results or conclusions should be relied upon by non-scientists.

So the blame is likely borne by a combination of the education system (explaining the importance of repeated scientific evaluation), the pervasiveness of lay "scientists" and *philosophers relying upon social media and other unreliable sources for their data, and the greater access that a random non-scientists have to studies that would normally be buried by time. Then you have people reaching their own conclusion and just finding a random study that supports that conclusion. That's the exact opposite of what the scientific method requires. The push by conservatives over the last few decades to erode scientific education (i.e creationism) is probably more likely to blame than any one scientist, doctor or certainly the medical/scientific community.
