:::::Do people really not understand what I'm saying? None of what Generalrelative has cited has anything to do with the point that I'm making. I'll try to put it in different words. Let's say the variance in the genetically determined intelligence of a single person is <math>\sigma^2</math>. From the definition of variance, it follows that the variance of a sample mean of a group of people is <math>\sigma^2/n</math>, where n is the number of people in the group. Since this variance is non-zero, and since intelligence is a continuous (not discrete) quantity, it is then ''implied'' that the probability of two sample means ─ even if taken from the same parent population ─ of being exactly the same is zero. So it is in fact ''impossible'' for there not to be any genetic differences between any two groups of people. Once again, this conclusion is trivially true and follows directly from the assumption that intelligence is a continuous quantity. One doesn't need any knowledge in genetics to reach this conclusion.
