The researchers recruited many of their subjects online, thus avoiding a common demographic problem in psychology research: drawing one's subjects from undergraduate students at major research universities. That may have other problems with how representative it is, however.
"We hypothesized that left- and right-wing authoritarianism are not mirror images but that they share a yet-unknown constellation of traits that might be considered the psychological “core” of authoritarianism." Seems like good research, and more than right-wingers projecting what they are criticized for onto the Left.
"We predicted that individuals high in LWA are generally dogmatic, hostile towards the present hierarchy, prejudiced and punitive towards perceived enemies, disposed towards moral absolutism, and tolerant of political violence."
They found these indicators:
- Anti-Hierarchical Aggression: "The rich should be stripped of their belongings and status."
- Anti-conventionalism: "Deep down, just about all conservatives are racist, sexist, and homophobic."
- Top-down Censorship: "I should have the right not to be exposed to offensive views."
The researchers then compared their subjects' LWA scores to various other psychological features:
Political ideology, RWA, Social Dominance Orientation (Dominance, Egalitarianism), Dogmatism, Political Intolerance, Personality (HEXACO: Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience -- Big Five + HH), Need for Cognitive Closure, Belief in Conspiracy Theories, Belief in Determinsm (Fatalism: "destiny" "fate", Scientific: material causes outside of the self). Emotional Political Polarization, Intellectual Humility, General Intelligence, Confirmatory Thinking, Reflectivity, Political Compasses, Objectivism (not Randism but tendencies to rely on empirical information and rational considerations when making decisions), Social Vigilantism, Belief in Certain Knowledge, Extreme Partisanship, Free Speech Suppression, Belief in a Dangerous World, Worldviews.
