Of course. But everyone has different knowledge of human history so it’s hard to say what counts as a priori for you versus me. For example, most americans have a-priori knowledge that rural americans are demographically whiter than urban americans, and could hypothesize global trends. If that counts as an a priori reason - I’ll take it. In summary: “A priori” is ambiguous here / not a very useful modifier afaict.
