Social psychological processes related to identities and stereotypes-such as threat, belonging uncertainty, identity incompatibility and bias-can be ignited by features and practices in educational contexts, often further disadvantaging members of minoritised or underrepresented groups. Such psychological processes are consequential and predict hard academic outcomes such as attainment and progression. Although this knowledge can be harrowing, it also gives us the power to intervene. We propose three ways in which social psychology can be used to help create more inclusive education systems: by using interventions wisely, working with teachers to collaboratively create inclusive classrooms, and by fighting bias. We offer concrete examples of how social psychology is helping to reduce educational inequalities in these ways, as well as some suggestions for the future.
