Beforehand, I should say that I'm neither a doctor nor a medical researcher. So my expertise is low.
However, I have some understanding about science in general. Probably, medical research is flawed like many other disciplines. If people see science as a way of proving what's true, then, it must fail. If people see science as a way of what sticks (or corroborates in Popper’s terms), then it’s not as bad as we think. As long as one paper by a young PhD can render industry-funded or other biased research obsolete, we can still expect progress. I would have expected the author to explain this in the article.
Otherwise many interesting bits of information. Especially the zombie science.
