But that is just conjecture. No one knows why they failed the test more often, only they did. It could have something to do with their written language, for example, and shapes similar to triangles and squares in it appearing in a certain pattern that isn't the basic repeating XXOXXOXXO... Or it could be music and rhythm is a big part of their culture, and XXOXX then follows with XXXO in a large number of their songs.
