I've long believed that some sort of national IQ test is required to participate in elections.
But if we did that then right-wing parties would win every single election worldwide!
"... That would enable us to come to some understanding of the temperamental proclivity towards those political attitudes, if any. We knew already that political conservatives tended to be low in trait openness (that's the creativity dimension) and high in trait conscientiousness; whereas political liberals tended to be high in trait openness and low in conscientiousness. And so one of the things that's extraordinarily interesting to know from the Big 5 perspective is that your political proclivities are very powerfully influenced by your temperament. And so one of the things you can think about with regard to the ongoing political discussions in the real world is that those discussions are actually attempts by people of different temperaments (1) trying to impose their temperament and viewpoints on the world, and (2) to engage in a dialogue with people who are actually quite different from they are."
