Discussion in another thread gave rise to this poll.
Simply, do you think evolution, with it's supposed changing of humans, left mental and physical competence equal among all races? I ask because I haven't been given much if any empirical proof or valuable evidence for either side. I, for one, am highly suspicious of the notion that evolution left all races equally intelligent.
The differences are insignificant, as one would reasonably expect given extremely minor gene pool variations. Different races are not remotely the same thing as different species.
On the intelligence issue you raise, I am not aware of even a single credible study that shows a statistically significant difference. Some people have made arguments based on reported mean IQ scores, but that is an inadequate basis from which to attempt such conclusions. Unless one can show, for example, the differences are statistically significant e.g., at a 95% level of confidence, one cannot draw the general conclusion you ask about. Furthermore, IQ, itself, only explains a portion of intelligence, and that further complicates the issue.
For illustrative purposes concerning the statistical issue, the following is a hypothetical case: Let's say there are two groups: A and B. A has a mean score of 110 and B has a mean score of 105. However, A has a standard deviation of 15 points while B has a standard deviation of 12 points. 95% confidence intervals (rounded to the nearest whole number) would be as follows: A: 81 to 139; B: 81 to 129. In other words, either group's true score could fall somewhere in the ranges set forth. On account of the overlap between the two group's ranges, one cannot state that A is better than B due to A's somewhat higher mean score.
Bottom line: There are no meaningful differences. Statistical rigor, not political correctness, is the basis for reaching such a conclusion.
