Keep the original post as written when you update it, and add the correction underneath.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. I will report back once I have actually tried it.

Clinical perspective, offered as context rather than as advice. It helps to ask what evidence would change your mind before you look at any. If nothing would, the discussion is not about evidence, and it is better to say so early than to spend nine posts discovering it.

Same experience, arrived at from the opposite direction.

There is a second half to this that has not been said yet. 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.

OP back with an update, since a thread like this is useless without one.

Late follow-up. I did not do what was suggested, I did something adjacent, and it worked; posting the difference in case it matters to somebody.
