I’d like a piece on it. Lack of correlation is counter-intuitive.
It sure is and that's probably why most people either don't know the facts or refuse to face them. About a year ago we got into the subject on this thread with Will88, and over in post 24 I went and got out the record going back to 1973 that showed the correlation was just not there.
Will got all mad at me and I don't think he's ever been willing to accept things as they are, but as far as why there's no correlation I can dig out the reasons for that too if you're interested.
