One concrete data point for the thread. One habit that pays for itself: post the method alongside the number. A figure without its method cannot be checked, and an unchecked figure is how this community accumulates folklore.

Following on from pat_auckland — and this may be the naive question:

Was that from a primary source or from a summary of one?

Careful with the causal language. Two things moving together in a period when five things changed is not a mechanism, and stating it as one makes the thread less useful to somebody reading it later.

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

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.

That reframing is the part I needed.
