Well, citing studies done before the 1980s is bad news, though even as something of a race realist I would give your essay an A; well argued, informative and somewhat convincing, again, even as I said, being a race realist. I have to call into question the argument you cited by Gould, not just because Gould is an idiot, but because Morton lived in the early 1800s. Gould likes to do that, however. It is very convenient for his arguments and agenda, to take data clearly obtained in bygone eras by scientists with insufficient controls in their experiments, instead of scientists of the modern era who have far more legitimate data, and cogent theories. In fact, Gould is largely silent, just indignant, or really just out-debated by many of these other researchers in modern times. Your section about microcephalin I think can be removed given the topic. As for your final argument about androgen levels, I think it was probably more destructive to your argument than constructive. It seems almost as if you are inadvertently insinuating that blacks have equal or perhaps higher(which you formerly argued but I seriously doubt) cranial capacities due to testosterone and not intelligence, or your just . Also, I think it is suspect the high preponderance of Jews cited in your study. Their numbers here seem vastly disproportionate and just too in line with many Jewish political and social ideals and experiments.
