That is, if a society consisted of nothing but one, or maybe even two quadras, could it survive? Could a society survive if there were two information elements totally unvalued by every single member of the population. For instance: if the world was all alphas and betas, could it survive with no one valuing Fi and Te? Or if the word were all gammas and deltas, how would things work with no value on Fe or Ti? I mean, in theory, one's dual helps to cover one's polr or weaknesses or whatever, but in practice... thoughts?
