I didn't know that. I could see that trend in the U.S., given how litigious people can be about medical treatments and alledged malpractice by everyone following consensus before research one can defend a treatment by saying it is current best practice, everyone does it after all.
I haven’t considered that angle but I think it comes down to human nature mostly. Trust in authorities seem to be our default mode of operation, and critical thinking is not something that’s taught in med school or valued in hospitals. Doctors are mostly not scientists. Ask your doctor to read a study and they might read the abstract. Most have no ability to evaluate the quality of a study
Do you think something like that happens?
