True. I read more medical papers than nearly all doctors and it’s not even close. Of course, it’s possible to go really wrong here if you are not rigorous. But that’s also true of credentialed scientists. However, it’s not all that hard to know a whole lot more than an “expert” if you study that topic intensively — because they will not have done that.

Many scientists and doctors want to be worshipped rather than to find the truth. And that is a real problem.
