The influence of ideologically biased echo chambers and filter bubbles on public discourse has long been a source of great concern. Is this concern justified, or is it simply a distraction from more pressing issues? Axel Bruns argues that the impact of echo chambers and filter bubbles is greatly exaggerated. This topic is driven by a moral panic over the role of networked social media in society. Our obsession with chambers and filter bubbles, and the deeply ingrained habit of blaming online platforms and the algorithms that underpin them for political destabilization, overshadows far more fundamental problems associated with the rise of populism and hyperpolarization in democratic societies. Weighing the evidence for and against the existence of echo chambers and filter bubbles, Bruns convincingly demonstrates why we must shift our attention to more pressing issues. This timely book will be of interest to sociologists, media scholars, cultural scholars, and anyone concerned with the challenges facing public debate and the democratic process itself.
