These studies were conducted along political axis lines, "liberal versus conservative". However, most arguments that are being employed in politics are not hard to invalidate in the strict sense by application of formal logic and counter examples. That being the case, it seems an obvious conclusion that one picks holes preferably in the opposition's arguments. Politics is about vested self interest, not logic.
