When I see an abstract like that, I think that what's about to follow is going to be a highly ideological and partisan op-ed dressed up as "science". Rephrased, the abstract is saying "Why isn't everyone a morally pure collectivist like me, and how can we fix that?" And the answer is: because you're not morally pure, the "common causes" you want us to unite behind are exaggerated and collectivism has a track record of being far more deadly than the things it's trying to solve. But that answer wouldn't be ideologically acceptable to academia.
