Pushing back on sarah_TO here. Filing an objection on the n=1 problem. Personal experience is genuine evidence about one person and very weak evidence about anybody else, and this thread keeps promoting the first into the second.

That holds where the measurement is reliable. Where it is noisy — and a lot of what gets tracked here is noisy — the same reasoning produces confident nonsense.

Ask again with the specifics and you will get a better answer than this one.

Thank you for spelling out the reasoning rather than just the conclusion. Taking it to my next appointment.

Adding the clinical framing, because it changes how the question reads. There is a difference between no evidence and evidence of no effect, and this subject is one where the two get swapped freely in both directions.

Same pattern here, and in the same order. Nothing to add that would improve it.
