Jung gave us racial archetyping- intuitive reasoning based on implanted memories that predate history (written history at least). Epistemology, in the attempt to discern whether knowledge exists a priori or a posteriori attempts to bundle ALL people neatly into one or the other categories. Like your article points out, it may not be that simple. Kant also broached the subject with his transcendental aesthetic (where he seems to attempt to argue both sides of the argument at the same time). Good article...certainly a different rubric from which to analyze the problem.
