physically impossible for their brains to be larger because the cranial sutures end much more abuptly on their skulls than white's, which does not
allow the brain as much room to expand over our years of evolution.
WHAT?!?! Thirty percent? Source? The research that I have seen has consistently found differences of less than 10%, with the most common figure
being in the 2% range. Honestly, a 30% difference in brain size doesn't even pass the laugh test.
Smaller brain (to size of organism) = less intelligent. Nothing racist about it at all, it's simple elementary-level science that you learn
about animals in the classroom.
The correlation between brain size and IQ is r=.40, meaning that r^2=.16. This means that brain size accounts for 16% of the variance in IQ scores.
That's a moderate correlation that leaves a lot of room for other factors to come into play. There are also methodological issues with this study,
but I won't get into that.
You also seem to overlook the fact that there could be a third variable (environmental in nature, perhaps), which leads to differences in both brain
size and IQ.
Some of us have moved beyond elementary-level science.
And simple logic dictactes that less intelligent will = less civilized, and less civilized will = higher "crime".
Logicians (you know, the people who study logic) actually call that "conjecture."
Here's a simple diagram that a scientist made comparing the brain size of a black male to a white male.
The one on top is the white male's brain, the one on the bottom is the black male's brain.
You're kidding, right? Robert Bean's 1906 drawing? You know that Bean failed to find a significant difference in brain size between races, right?
His hypothesis was that this was because the brains were from lower-class whites and upper-class blacks. He couldn't verify this, of course, and was
just grasping at straws to explain the lack of difference. Be honest, you're screwing with the other ATSers with this crap, right?
Intelligence, brain size, and race is the correct answer and no scientist or professional in this field will disagree with me, though they will
not openly talk about it either (don't want to lose our jobs).
You just cited Bean. You made the outlandish claim that there is a 30% difference in brain size between races. Furthermore, no human population has
ever maintained itself in reproductive isolation for more than a few centuries, so the relative homogeneity of humans makes the entire premise highly
questionable.
Unless you're still living in 1909, nobody would agree with you.
And don't dare cry racism, it get's old.
So does sloppy psuedo-science, Professor.
It's not like I'm lying to you here, go to the morgue and have them split open the skull of a deceased white or asian male and then a
deceased black male and then compare brain sizes. The former are much, much larger that you would actually be quite surprised at the difference. ~30%
is a large amount.
You don't think that there might be an issue with sample size?
No bias here, no racism. It's simple science that can be measured and tested.
Ooookay then.
