>it's pretty easy to believe your own experience over even a well-constructed "randomised controlled trial".

In my youth, I would have argued this was bad. Now, I tend to agree. Not that studies are worthless; but they are just part of the accumulation of evidence, and when they contradict a clear result you are directly seeing, you need to weight the evidence appropriately.

(Obviously, replicated studies showing clear effects should be more heavily weighted.)

Everything is just shifting odds.
