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.

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

Adding the part of the answer the thread has not reached. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.
