> Do you expect a single study This is a meta study. > to overturn decades of research and medical practice? “Medical practice” has an atrocious record of being based in fact. There is, in fact, plenty of research on placebo, and the preponderance seems to suggest that it’s weak or non-existent. > E.g. placebos still work when you know it's a placebo, it works for animals This is consistent with, and in fact favors, the theory that it’s actually just mean reversion. > Maybe Bad Science by Ben Goldacre is a good starting point as a book I don’t think pop scientism books are a good place to start.
