This book firmly positions lived experience-led expertise as a unique and compelling form of knowledge in decolonising and disrupting research, teaching and advocacy. Based on the insights of people with first-hand experiences, each chapter presents unique accounts and reflections on a diverse range of social justice issues. Together, the authors’ perspectives centre lived experiences in the production of knowledge, challenge outsider-imposed views, and create new research and writing norms. They demonstrate that, when lived experience experts lead the way, their knowledge of how to address social injustices can enrich, transform and decolonise research, teaching and advocacy. This collection is an invaluable resource for academic and community-based researchers, practitioners, advocates, educators, policy makers, students and people whose lived experiences and views continue to be marginalised across diverse settings. “This book adds to the growing body of reflections on and critical enquiry into, the impact of perceptions around whose voice counts in knowledge production. Challenging historical understandings of the basis of robust knowledge is vital to illuminating enduring epistemic injustice.” Tina Cook, Liverpool Hope University “This book adds to the growing body of reflections on and critical enquiry into, the impact of perceptions around whose voice counts in knowledge production.
