Just because it looks like science does not mean it’s science. Many people don’t realize how much of a problem this is these days, the sheer number of studies that are truly worthless, or close. Junk journals are really a thing, from the merely pathetic to the outright fraudulent. Even in real journals there are way too many ill-conceived studies that don’t really do much except muddy the waters. Nearly all review papers in musculoskeletal medicine point out that most of the evidence available is poor quality: high risk of bias, underpowered, poorly controlled, etc. And that’s the papers that made the cut for review!
