I replicated and extended Eadeh and Chang (2019; Study 2) who found that reading a story about pollution harming a child increased self-reported liberalism and increased support for environmental regulation policies through greater negative affect (i.e., anger and disgust) (Hypothesis 1). Eadeh and Chang’s (2019) threat-affordance model posits that perceived threat can increase greater support for liberalism or greater support for conservatism, depending on the type of threat. In contrast, Jost and colleagues’ (2003) system justification theory posits that perceived threat asymmetrically predicts greater support for conservatism and greater systemsupporting collective action. This article advances a synthesis of these two theoretical perspectives such that the threat of environmental pollution (a) increases system-challenging collective action intentions and donation behavior through negative affect (Hypothesis 2) and (b) increases liberalism, support for environmental regulation, collection action intentions, and donation behavior through lower system justification (moderated by empathy), greater perceived injustice, and greater negative affect (in order; Hypothesis 3).
