We’ve had many a discussion about IQ on this blog. The chart below seems to provide an unequivocal conclusion. The law of large numbers always wins. The good old statistical conclusions from normal distribution graphs are pretty clear. On an individual basis, there will be really smart white and black people. There also will be really dumb white and black people. But, according to this chart, the overall distribution of IQs shows whites having an average of 100 and blacks having an average of about 83.
When I see results like this, I ask why.
An IQ test measures intelligence based upon a myriad of questions. The test was created by humans. How much of my IQ score is simply based upon my genes? Are we born with an IQ score already ingrained? Does the white race automatically have a 17 point advantage over the black race?
Or, is IQ a function of education, upbringing, environment, and individual motivation? Are overall white IQ scores higher because they are more likely to be raised in two parent households and have access to better educational opportunities? Are overall black IQ scores lower because the majority are raised in one parent households and have less educational opportunities?
The question seems to be nature versus nurture. What do you think?
