The figure of the imposter can stir complicated emotions, from intrigue to suspicion and fear. But what insights can these troublesome figures provide into the social relations and cultural forms from which they emerge? Edited by leading scholars in the field, this volume explores the question through a diverse range of empirical cases, including magicians, spirit possession, fake Instagram followers, fake art and fraudulent scientists. Proposing thinking with imposters as a valuable new tool of analysis in the social sciences and humanities, this revolutionary book shows how the figure of the imposter can help upend social theory.
