Over on the IAP-CHC listserv there has been a spirited exchange on the existence of g and the strengths and weaknesses of different test g-scores. During the exchange, my friend and colleague, Dr. Sam Ortiz, resurrected (thanks Sam...youdaman!) two long comments made by John Horn (yes, the "H" in CHC theory) to an early version of the IAP-CHC listserv (in June of 1999).
I've taken that resurrected post, converted it to a pdf file, and have posted a link to this file (click here). This is an important informal communication from John Horn regarding his postion on g.
