why would this model be considered better than the by now already traditional bi-dimensional spectrum, with different axes for economic (collectivist vs individualist) and social (libertarian vs authoritarian) issues? to me, it comes across as a failure to realize that it's two separate and independent dimensions, in that it sort of has two axes, but limits how far one can go in the combinations to force the choices into a triangle rather than e.g. a square
