In looking for that article by Kathleen, I found one post saying "but i.q. is increasing". I thought that was the most stupid thing anybody said ever. I mean, maybe when we're stupid, anybody less stupid than us looks rather smart. I'd say I.Q. is decreasing in direct proportion to the size of our brain. Or rather, we've grown stupider by about 11% in the last 30,000 years.

Don't confuse intellect with knowledge. The two are not synonymous. We might know a lot more than we did back then but we're not smarter otherwise we'd do something about our shrinking brain, wouldn't we. I mean, if we were smarter we would. But we're not because our brains are smaller therefore we don't do anything about it.

It's like what I've been saying, a priori the brain can't function properly when it's malnourished.
