Sex and IQ I have just posted here the original Lynn & Irwing paper. The ferocity of the attack on the paper is exactly what we would expect of a genuine contribution to the advancement of knowledge. Work that overturns what has long been believed will of course be resisted. So to allow the general reader to see for himself/herself that the paper is utterly sound, I have reproduced it. Out of respect for copyright, however, I have omitted the Tables and References (Essential to serious scholars). Most readers of the paper will be amazed to recognize nothing in it that resembles what critics like Blinkhorn have said about it. Those who know of the uneasy relationship that Leftists have with the truth will not be surprised, however. I have posted a PDF of Blinkhorn's rant here. Blinkhorn was so desperate that he criticized an addendum to the main Lynn & Irwing paper and ignored the main paper altogether. The addendum dealt with results from groups of students and I certainly think that you can conclude nothing from such data. But the main paper was a collection of results from a large number of general population samples and criticisms such as those made by Blinkhorn were anticipated there and fully dealt with. To tell you in a few words what Lynn & Irwing found: Most IQ test data originates from surveys of students. And from such data it is reasonable to conclude that males and females have equal average IQs. And in the past, everybody concluded that. Lynn & Irwing however submit that males are "late bloomers" and that male IQ goes on increasing beyond the age of 16 while female IQ flattens out. And when they looked carefully at all the past studies of IQ among ADULT populations, that is exactly what the data showed. Just to be perfectly clear, I should perhaps add that Lynn's finding is in addition to the long-known finding that males have a greater variance in their IQ scores. Female IQ scores cluster much more tightly around the average for their sex than the scores of men do. So there are not only more very bright men than women but also more very dumb men than women. I have written a fair bit in approval of Lynn's work so in case anybody thinks that I am incapable of being critical of him, I should perhaps point out that I have criticized some of his early work in another field.

Well, and I think what a lot of people don't realize is that an average says nothing about an individual other than it puts one in a group represented by that average. So, it really doesn't matter that the average difference is 5 points or 15 points from the perspective of an individual who is curious about his or her intelligence as measured by IQ tests. I understand that people identify with their gender and hold allegiance to it for various reasons (like equality in x,y,z), but this need not affect one's self-worth as an individual at a given level of intelligence. Sure, it's nice to know where you stand, and it's not nice to know that you stand below someone who is equally intelligent as you but has a higher score (and, anyway, in this case, that would be the man, not the woman), but the fact is that a person has whatever he or she has, and using it is far more important than comparing it to a group, not to mention the fact that not all socially esteemed mental abilities are measured on IQ tests. Most are, I think, but not all, including creativity and artistic abilities.
