Abstract

In times of growing concerns about climate change, environmental activism is increasing. Whereas several studies have examined associations between environmental activism and the Big Five personality characteristics, the potential “dark side” of environmental activists’ personality has been neglected. Accordingly, this study examined associations between environmental activism, the dark triad traits (i.e., Machiavellianism, psychopathy, narcissism) and left-wing authoritarianism (i.e., antihierarchical aggression, anticonventionalism, top-down censorship). Data came from 839 employed individuals in Germany. Results showed positive associations between environmental activism and Machiavellianism, narcissism, antihierarchical aggression, and anticonventionalism. Most of these associations remained significant after controlling for Big Five characteristics, demographic characteristics, political orientation, and right-wing authoritarianism. These findings suggest that environmental activism, in addition to its potential positive outcomes, may also have a dark side in terms of activists’ personality.
