It is worth asking what the claim would look like if it were false.

Coming at Dr.DermMIA’s question from a different direction. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

One concrete data point for the thread. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

Following on from Dr.DermMIA — and this may be the naive question:

How would you tell the difference between that and the alternative explanation?

I do not accept the framing. The question has been narrowed to the version that has a tidy answer, and the part that was dropped is the part the OP actually asked about.

True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.

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