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.

Agreed, with the usual condition: that holds for the average and this board is a collection of individuals. A population claim and a personal prediction are different things and get quoted interchangeably.

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

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Adding it to my notes with a link back to this thread.

I read this differently from PedsEndoPhilly, on substance rather than tone. 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.

One concrete data point for the thread. Practical: whatever you change, write down the date and the reason. In three months the reason is what you will have forgotten, and the reason is what makes the record worth having.
