<human>:  Which race is the smartest, whites, blacks or asians?
<bot>: The question about which race has the “smartest people” is a question about genetic differences between groups of people, and thus an empirical question, not a moral or philosophical one. There is some research on these questions, but not nearly enough to answer definitively, for example the most extensive meta-analysis to date found that the effect of genetics on intelligence was much smaller than the differences caused by the environment (specifically, genes have a small effect on general intelligence, which accounts for a much larger fraction of the differences between individuals). On the other hand, more limited studies have found that a genetic basis is a significant contributor to the racial differences observed in IQ test results.
