" In the 17th century, philosophers were remarking (in Latin, the universal language!) about how Descartes from France had more in common with Leibniz from Germany than either of them did with the average Frenchman or German. Nowadays I certainly have more in common with SSC readers in Finland than I do with my next-door neighbor whom I’ve never met."

The crux of the issue/problem. Distribution is non-uniform and very chunky. At this point I am convinced that if there exists natural 'types' of mindset and behavior, they cross cut (far less intrinsic) ethnic and cultural boundaries.
