If it was so then caste system was correct. Fair skinned North Indian Brahmins were better than dark skinned indigenous population and the former deserved to know the Vedas and latter did not.
Both these groups are caucasian. Even if the groups would not share the same race and same average IQ, it would be stupid and inefficient thing to do since individual variation in IQ is huge and many people from the lower caste would have higher IQ than many brahmins.
There is no well respected study that shows intelligence is a genetically inherited trait.
There are quite a few studies on heredity of IQ and I have researched this problem in detail 1-2 years ago and search for all studies on the matter. Only a couple of good studies with good methodology exist and they found a 0.7 is genetical and 0.3 environmental. Also, children over a certain age do not change IQ. Environment can only play a role at a small age and not in adolescence, this is accepted by all studies.
I will search for the studies on heredity of IQ and will post them here.
And where is the source for 9-12 months claim?
True, no source for this. Somebody else made this claim without posting a source and I have just repeated it without verifying it. You are right on this, wrong way for me to proceed.
It is from 1976! That was a very different society.
There are many other studies except that one. Even in the PC studies they start with "despite all the studies on this matter", accepting that this is the general consensus. This also corresponds with the 0.7-0.3 heredity-environment numbers that I am well informed on.
You are reaching the conclusion that an entire race is stupid based on study of 130 individuals in one state of USA?
1. I am not reaching the conclusion that a certain race is stupid. I am making the conclusion that differences in average IQ of races exist and that they are in big part attributed to genetics.
2. I am not making that conclusion based on that 1976 study that is just a random link that popped up on top of google when you asked about a source. I am making that conclusion based on hundreds of tests done ever since IQ testing had begun that all say the same things. I am also using observation from real life when making that statement. (aboriginals not discovering the wheel and some not even knowing how to make fire, sub-saharans never building any cities) I also find it incredible how some might believe all humanoid races have the same average IQ, all dog breeds have same average IQ, all birds have same average IQ, etc. when the probability for such a thing is extraordinary small. Even without a billion studies in the field all saying the same thing ever since IQ testing was invented, it does not take a Stu Ungar brain to measure the likeliness of such a probability.
