there're more studies on related splits that map pretty neatly onto this one, like how conservatives have a high disgust reaction which they conflate with moral conscience eg "queer people make me feel icky therefore they are objectively gross and immoral"
because of this they don’t “cut off” their kids for their political views, they simply make them homeless because they are a let down
yup. left/right psychological differences is a psychological finding i have high credence in because there's so many corroborating findings
