I don’t think political beliefs have anything to do with intelligence. My recent g-friend was a Phd educated social work. Smarter than ill ever be. Great researcher, great college professor, etc. That said, she was so ignorant. She said “hate” in every other sentence. She openly stated she hated this person or group of people or situation. She was genuinely unhappy with herself and lashed out at people in public. My only guess is something traumatic happened to her as a child. I’ve never see such an intelligent person in a 7 year old emotional state.
I agree 100%. That’s why the study is faulty.
