@Leon "I'm sure that those studies must have been done by liberals because when you try to bring any reason to their minds, they respond with trigger words like racism, sexism, and xenophobia."
Would you fin i surprising if, in principle, psychologists were able i match up personality traits with probably party affiliations? Even at 70% chance of matching.
If you can effectively test all components of a person's personality.
I can't guess, from first principles, what the common traits would be. But having a 'risk-averse' conservative party, and a 'open-minded' liberal party, makes some amount of sense.
Evolution drives us to be risk-averse - so we don't die - and to be open-minded - so we don't stagnate when changes hit us.
Those two idea may clash, you can't try new things while being overly risk-averse; but it is possible that having two competing strategies at the same time increases the likelihood that the collective will survive.
It seems pretty coherent to me, but the research is pretty hard to do, and it may ne that there is more factors at work than just personality.
