The figures, for anyone assembling their own picture. If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way. Most of the apparent contradictions in these threads dissolve at that step.

I would rather be corrected than agreed with, if it comes to it.

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

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

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. 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.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

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.

Bookmarking. The distinction being drawn above is the one nobody else makes. Sending this to two other people who asked me the same thing last week.
