The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either.

That is right, and it stops being right at the edges. The general case is well behaved; the interesting cases in this thread are all at the boundary where the general case breaks.

Agreed, with a caveat about community reputation: it is a lagging indicator.

Saving this. It is the first explanation that did not require me to already understand it. Adding it to my notes with a link back to this thread.

I read this differently from TinaHashiRN, on substance rather than tone. I think the framing smuggles in the conclusion. Ask it the other way round and the obvious answer reverses, which usually means the question is doing the work.

One concrete data point for the thread. If you are going to change something, change one thing and give it long enough to express itself. Four weeks is the usual minimum for anything pharmacological on this board, and two weeks of data has told you almost nothing.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part.
