Adding the clinical framing, because it changes how the question reads. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.

I read this differently from james_edin, on substance rather than tone. The objection nobody has made: this only works if the measurement is doing what we assume it is doing, and that assumption has not been tested here.

Agreed, and the size of the effect matters as much as its existence. Something real and small gets treated here as though it were real and decisive.

Genuinely useful, thank you. I had the facts and not the framework. I will report back once I have actually tried it.
