If you are going to change something, change one thing and give it long enough to express itself.

That reframing is the part I needed. Sending this to two other people who asked me the same thing last week.

From the other side of the consultation, briefly. 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.

Same pattern here, and in the same order. I had assumed I was the exception until I read this.

Adding the part of the answer the thread has not reached. 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.

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

Following up because I said I would. I changed one thing, left everything else alone, and waited the full interval before looking. It resolved, and I cannot prove which half of that did it.
