The distinction that resolves most of these threads is between what is true on average and what is true for one person.

Coming at PedsEndoPhilly’s question from a different direction. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either.

That is the short version; the long version is somebody else's post.

Adding the numbers, since they settle part of this. The boring version of this is the one that works, and the boring version is: measure a baseline, change one variable, wait, measure again under the same conditions. Nobody wants that answer and it is still the answer.

Correct me if the detail matters more than I have assumed.

A narrower follow-up, since the general answer is now clear:

How would you tell the difference between that and the alternative explanation?

I read this differently from wendy_avl, on substance rather than tone. I would resist the confidence. Half of what this board was certain about two years ago has since been quietly dropped, and nobody went back to correct the threads.

Closing the loop on my own question.

Coming back a few months on. It held. Nothing dramatic to report, which is the report.
