andy, I understand what you say, but I was not referring to the entire discussion in my comment. I posted it impulsively after reading some specific comments that seemed to rather seriously discuss the hypothetical merits of one point of IQ and such. I only meant that it is pointless to discuss it as if everything is so precise and quantifiable, forgetting the fact that the concept itself is hazy (even though, as everyone knows, you can roughly categorize people as being more intelligent/less intelligent when the differences are very clear)
