The introduction highlights the urgent global challenges facing society—from economic instability and climate change to inequality, migration and technological disruption. It argues that addressing these complex issues requires not only accurate information but also the unique insights offered by the social sciences. The book features 14 essays by leading scholars, each demonstrating how social science perspectives deepen understanding and inform effective policy. While rooted in the UK context, the volume takes a global view, emphasising interconnectedness and the value of interdisciplinary research. This second edition includes updated and newly commissioned chapters on topics such as decolonial theory, climate justice, and AI. Ultimately, the introduction makes a compelling case for the indispensable role of social science in shaping a more just, informed and sustainable future..
