Once we acknowledge that race is an important biological classification of humans, it should be acceptable to study the durable ways the races differ in average intelligence, academic performance, criminal behavior, and sexual behavior.
Only if you also acknowledge that biological classifications apply to a group average, not to individuals. Other biological classifications of humans include: hair color, eye color, and height. Can you use any of those criteria to study the ways individuals differ in average intelligence, academic performance, criminal behavior, or sexual behavior? Intelligence tests have been shown to be culturally biased, so it’s hard to use them to determine average intelligence across cultures. Can you determine that all people over 6′5″ are likely to excel at playing basketball, or that people with brown hair are going to be better academically than people with blond hair? Are blue-eyed people more likely to be criminals; are green-eyed people more likely to be gay? Sexual behavior is not genetic; sexual orientation appears to be a spectrum.
Using one aspect of a person’s biological makeup is pointless, as we’re all a combination of biological classifications, and when it comes to analyzing individuals, it becomes pointless. Can you take two babies, one who is black, brown-eyed, black-haired and one who is white, green-eyed and blond, and expect to make accurate predictions of how they will turn out in 10 or 20 years? How are you going to classify multi-racial individuals?
Since we all associate with a variety of people meeting various combinations of biological classifications, it’s impossible to make predictions based on group averages. Why not try meeting and interacting with people as individuals, rather than judging them on the basis of biological classifications over which they have no control?
