Re: More invalid conclusions & unsubstantiated assertions in place of any real argume

Hey Crash,

Didn't see this post until now. I have some questions because.. I'm interested in this stuff, but I haven't come across literature stating what you're stating. I'm asking for sources for the purpose of expanding my own knowledge on the subject:

There's no selection pressure for larger brains (and considerable pressure in the developing world against)

I can imagine why this may be so... but I've never read / heard an argument for it. Can you elaborate a bit, and point to a source?

It's a well-known neurological fact that the IQ of a population increases over time.

The wording sounds strange to me... as far as I know, IQ is not descriptive at the level of neurology, but rather psychology. Anyway, I also had no idea that IQ is known to increase over time. Can you point me to a source for that as well?

Thanks Crash.

Ben

Re: More invalid conclusions & unsubstantiated assertions in place of any real argume

MarkAustin,

However, if you compare average brain sizes between species there is a rough but good correlation between the brain:body mass ratio and intelligence. This correlation improves if brain complexity is considered.

I was posting about this in another thread. I was wondering if you'd be so kind to forward some references for both of these claims of correlation. It's tangentially related to my field of study, and I'm having trouble coming up with good experimental and/or review papers that really address the subject so directly.

But I'm not a great searcher yet... anyway, if you could do that, I'd really appreciate it.

Thanks,
Ben
