Promoting Climate Actions: A Cognitive-Constraints Approach

Many Americans do not view climate change as a threat requiring urgent action. Moreover, among U.S. conservatives, higher science literacy is paradoxically associated with higher anthropogenic climate-change skepticism. The present study harnessed the power of two cognitive constraints essential to belief formation and revision to design educational materials that can mitigate these problems. The key role of the coherence and causal-invariance constraints, which map onto two narrative proclivities that anthropologists have identified as universal, predicts that climate-change information embedded in scientific explanations of (indisputable) everyday observations within a coherent personal moral narrative, juxtaposed with reasoners’ typically less coherent explanations, will be more persuasive than climate-change information by itself. An experiment conducted in U.S. states with the highest level of climate skepticism demonstrates that across the political spectrum, conveying science information using materials that leverage these constraints raises both appreciation of science and willingness to take pro-climate actions.
