This book articulates how psychologists can use their theory, research, and intervention to generate insights into emancipatory social change that is necessary to solve social and psychological problems. These include racism, sexism, civil rights, poverty, militarism, education, and politics. 

Psychology was not developed to directly address social issues. It must therefore be reconceptualised to fulfil this aim. In this book Carl Ratner makes use of Vygotsky’s psychological approach known as ‘cultural-historical psychology’, supplemented by Martin-Baro’s Liberation Psychology and the work of Bourdieu and Foucault to develop an emancipatory psychological theory. This approach is then utilized to lay out a specific program of social and psychological emancipation. This reconstructed psychological theory is also used to evaluate populist movements that aim at social and psychological emancipation. Ratner posits that populism is inadequate to solve social and psychological problems because it misunderstands the nature of society and what it takes to improve society and psychology. This is demonstrated through wide-ranging examples including populist feminism, populist socialism, and populist distortions of liberation psychology and cultural-historical psychology.

This lively critique opens a pathway for academic across the social sciences concerned with how their disciplines can be oriented toward understanding and solving social-psychological problems, and will appeal to wide readership including policy makers, and social activists.
