AN OVERWHELMING MAJORITY OF SCIENTIFIC STUDIES PROVE DEFINITIVELY THAT RIGHT WING BELIEFS ARE HEAVILY CORRELATED WITH LOW INTELLIGENCE:
Bright Minds and Dark Attitudes: Lower Cognitive Ability Predicts Greater Prejudice Through Right-Wing Ideology and Low Intergroup Contact
Low IQ & Conservative Beliefs Linked to Prejudice
Study links low intelligence with right-wing beliefs
Right-wing ideology and numeracy: A perception of greater ability, but poorer performance
Conservatism and cognitive ability
Intelligent people are more likely to be left-wing, says science
People with lower emotional intelligence are more likely to hold right-wing views, study finds
