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)
Rather strangely, all the intelligent people here seem to be talking about "intelligence" as if it could be measured by points on some linear scale. It probably varies with age, time, mood, etc. even for a single person. And there is hardly any good definition of what it is to begin with.
