Effective climate change mitigation is a social dilemma: the benefits are shared collectively while the costs are often private. To solve this dilemma, we argue that we must first understand the nature of human cooperation. This constitutes a shift in the field of psychology and climate change, which has traditionally focused more intensely on risk-perception, miscommunication or time discounting, to explain the lack of climate action. We review three social cognition mechanisms that regulate cooperation: norm detection, reputation management, and fairness computation. We show that these cognitive mechanisms can prevent behavioral change and lead to ineffective policies. At the same time, the very same mechanisms can be leveraged as powerful solutions for effective climate change mitigation.
The belief-action gap was originally conceptualized by psychologists who aimed to ground behaviour in beliefs but found that their models had little predictive value. The recurrent use of this concept often comes with the assumption that human behaviour is somewhat irrational or weirdly misaligned with their beliefs. This gap is particularly striking in the environmental domain, where many people seemingly think one way but act another. In this chapter, we review a number of factors that hinder general beliefs from translating into actual behaviours. We emphasize the existence of measurement issues, information deficits about the exact impact of one’s actions, structural factors and psychological factors that together impact the robustness of the association between beliefs and actions. In particular, socio-cognitive factors have a massive impact on people’s decisions to act in ways that are aligned with their deep- seated beliefs. Once all these factors are properly taken into account, it becomes clear that the belief-action gap is not a token of human irrationality but should in fact be expected.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
