Well Dave, he did sting me into looking up the stuff he goes on about. I don't think he actually understands it well enough to articulate it clearly to us is what I concluded. And it's odd that he agrees with me about the uselessness of IQ tests yet chose to beat his chest over his own hefty score. His hobby horse is interesting but he's declined to enlighten us on it (another irony, if you take the play on words).
