If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way.

Fair, and it stops being fair at the extremes. The middle of the range is well understood; the ends are where the honest answer is that nobody knows.

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

Genuinely useful, thank you. I had the facts and not the framework. Printing the relevant bit and taking it with me.

Clinical perspective, offered as context rather than as advice. If two explanations both fit, the useful question is which one predicts something the other does not. That is answerable; arguing about which sounds more plausible is not.

Adding the part of the answer the thread has not reached. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.
