Abstract
Many people do not act together against climate change or social inequalities because they feel they or their group cannot make a difference. Understanding how people come to feel that they can achieve something (a perception of self-efficacy) is therefore crucial for motivating people to act together for a better world. However, it is difficult to summarize already existing self-efficacy research because previous studies have used many different ways of naming and measuring it. In this article, we uncover the problems that this raises and propose the triple-A framework as a solution. This new framework shows which agents, actions, and aims are important for understanding self-efficacy. By offering specific recommendations for measuring self-efficacy, the triple-A framework creates a basis for mobilizing human agency in the context of climate change and social injustice.
