What evidence exists that Blacks and Whites have equal intelligence?

Could you list the totality of the scientific literature on race and brain size?

 

LOL! Not without cluttering the thread. The Lieberman article has most of the relevant studies so you can check his references. If you have a better article let us know.

 

Ouch

In animals, bigger brain means more self-control

 

black people and white people have the same size brains.

 

That study made between species comparisons:

The conclusion: animals with larger brains, like chimps, have much better self control than those with small noggins, like rodents.

Refer back to Graves email:

Second, the relationship between "intelligence" and brain size/body ratio holds broadly over species level, but not within a species.

In any case it makes no difference for humans since there are no racial hierarchies in brain size.

 

First of all, men have larger brains than women even when body mass is taken into account, so you're making an overgeneralized statement here. Brain size in humans is not only related to gender, also to height, at the least. Human groups do not all have equal-sized brains.

 

Sorry, but I don't buy your views on European history. I don't think you've studied WW2 to the same depth. Any German tanker coming up against a KV 1 or 2 couldn't even knock it out. German tanks were mainly better at the start of the war because they had radios and better trained crews.

Determination and a will to fight will go a long way for anyone fighting a war. It is the creative genius---the highest form of intelligence---that gives the true edge. And since 95% of all major modern inventions came from Westerners, this leaves little doubt who the "so-called" "smartest" people are.

So what have our Arab friends done LATELY for the world since helping form the alphabet, some math and stargazing? Anything much of greatness to make the world a better place? Anything in the last 1500 years?

The best Arab countries can do now is copy, steal or buy military technology. They haven't created a single new technology on their own as far as I know. For the average Arab fighting in the Mid-East today, using an AK rifle or RGP against a Abrams tank, or an A-10 attack aircraft----they may as well be an ant throwing grass seeds at a lawnmower.

Again, I am 180 degrees off on your educational ideas. All K-12 ed should be funded by the locals. Because it is so obvious that test scores follow ethnic lines I would be a sadist if I linked tax dollars to students' test scores.

The citizens of the local communities should bear full responisiblity for the their schools. The locals should take care of their own poor. Why should so many areas with crumbling schools care if they survive on outside entitlements? Where is the incentive to do better?

 

I never said that they did. But the variance in brain size does not determine intelligence within the species normal range.

 

Exactly. Gould looked at the data (as opposed to the skulls); he at least qualified his conclusions.

Scum such as Lieberman took Gould's conclusions and passed the results off as Gould had done actual skull measurements - claiming Morton's original measurements were disproven without qualification.

The fraud was Gould, to be sure; the scum were the ones accepting of this approach.

It doesn't take a professor to know that Gould's approach should have been dismissed, not Morton.

However, for ideologically driven lunatics, such as Lieberman, someone taking guesses was good enough to accept - if the results were in line with personal belief.

Would you have accepted Gould's work 'disproving Morton' knowing that he did not measure a single of his skulls?

That doesn't fly anywhere else.

 

Calling Lieberman scum and a lunatic is completely unfounded and just more name-calling in a vein attempt to discredit him. Again you have disqualified yourself from being a serious debate opponent by refusing to read my post and dismissing sources for bogus reasons.

 

Here are the facts on race and brain volume via MRI:

Average White cerebrum volume: 1173.4 cm^3

Average Black cerebrum volume 1076.0 cm^3

You can read the discussion and results yourself to confirm age, education and socio-economic markers were controlled.

There does seem to be racially correlated variation in brain size. For example South Chinese on the same latitude as South Asian Indians have larger brains and higher IQs. The correlation to latitude is due to heat retention and may be in non-cognitive brain matter (most of it). The racially correlated variation is probably in cognitive matter.

 

Anyway, brain size is just one factor and many other things clearly affect IQ, such as neuron connection density, nerve composition (which varies a lot) etc.

 

Interesting study. The sample size is rather small. I emailed the lead author for comment.

Beals, Smith and Dodd (1984) already established that there is a low correlation between cranial size and race and high correlation between cranial size and climate.

Do you have a source for brain size comparison between these two populations?

That's speculation.

I don't doubt that there are aspects of brain structure that influence intelligence but as Graves noted the brain's development is highly impacted by developmental and environmental factors, not just genetic factors. To prove that there are racial differences in brain structure related to intelligence one would have to tie any observed physical difference to genetics.

 

Not to mention the MRI study's limitations according to its own authors:

 

This weird obsession the far right and white nationalists have with black/white IQ's is downright hilarious. I guess when you're a complete failure in life, all you have to make yourself feel better is to put down black/brown people as much as you can.

 

I remember hearing in my US History class that some of the staunchest supporters of racialized slavery in the antebellum South were poor Whites who didn't actually own any slaves. Apparently those guys needed someone to look down upon. I don't know if our opponents here qualify as socioeconomically underclass (they can at least afford Internet), but I do imagine them to be pathetic human beings as you said.

White Homicide Worldwide, from the SPLC:

 

In fact many extremely successful people are also concerned with the potential destruction of Western civilization by Communists. Nice original ad hominem though: 'my opponent is a loser'. Not ironic at all.

 

Yes, that must explain why East Asians have wider hips than Whites than Blacks - presumably for larger head babies: It's 'environment'.

 

Actually that hip factor probably has more to do with cold-adapted populations generally having broader, stockier physiques than heat-adapted ones. You can also see this in European Neanderthals compared with modern Homo sapiens (which stayed in Africa longer):

What's funny is that Black babies, born a week earlier than Whites, are more mature; this corresponds to lower brain volume as larger brain size is a bottleneck for development.

Btw, this summary of brain weight at autopsy - also addressing Tobias' supposed findings - should dispel some of the earlier spread myths:

Also on baby and child head size and race:

Rushton's research is garbage. He deliberately misinterpreted a lot of studies on physical maturation to support his Life-History Theory, which is entirely based on the ecological concept of r/K selection. He selectively cited data to fit the r-K continuum in order to make arguments about evolutionarily determined racial differences but his theory was proven to be wrong by Joseph Graves, a prominent evolutionary biologist. During a debate with a Rushton supporter I emailed Graves as well as Scott MacEachern, an archeologist and anthropologist who pointed out other flaws with Rushton's work.

They had the following to say about Rushton's work:

 

Graves also looked at Rushton's research on brain size and found many errors including his interpretation of Tobias:

Rushton's interpretation of Ho et al. (1980) is also flawed. He failed to address the follow up commentary of Ho and his colleagues on race and brain size:

 

Is there a particular reason why you pulled an extract which I didn't quote into a quote of mine to make it look like I had quoted that portion of Rushton's work?

Let's stick with the fact Blacks are born earlier more developed than Whites than Asians and have smaller head size - indicating brain volume differences begin before birth and are endemic for the three races.
