Therefore, I can't rule out a priori that there may be a genetic component of brain power that means that there is variation, on average, between identifiable sub-groups with respect to identifiable components of brain power. While Raghu would rather we not try and answer these questions, answers may be coming and we should be prepared for those answers.
^^^^^ CB: You can rule out that there is some correlation between the genes for "white" skin color and some genetic component for superior brain power based on the _empirical_ evidence, not a priori. This question has been investigated for many decades, and we have the answer. Surely , you know this is no longer a question in the state of a priori, i.e. without any experiential evidence.
