1. If you look at the consensus in the field of psychology, human beings are probably not that good at making the kind of assessment you're talking about with any degree of accuracy. For instance, once you form a belief that there is a difference in competence between people of different races, you will become heavily biased to attend to examples which confirm your belief, and you will be biased to disregard examples which contradict your belief. Humans are just not perfect bayesian reasoning machines.
2. In the social contract of western, liberal society, we have broadly agreed that people should not be judged by their immutable characteristics. So in a sense, yes you are not allowed to "pattern match by race", according to the standing rules of society.
3. This rule helps protect us from the dangers of racial thinking. For instance, a belief about the relative merit or competence of one race can easily jump the gap from being descriptive to prescriptive when one goes around treating people by different standards based on their group identity. There is so much variance within every demographic group that even if there were some statistically significant difference between groups, you would be doing a massive injustice to so many of the individuals in that group to judge them by the "representative member".
