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.

I would rather be corrected than agreed with, if it comes to it.

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.

This answered a question I did not know how to ask.

Adding the clinical framing, because it changes how the question reads. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

Adding a me-too, because a thread of one person's experience is not much use. The detail I would add is minor and it is already implied above.
