What makes a fascist? Are there character traits that make someone more likely to vote for the far right? The Authoritarian Personality is not only one of the most significant works of social psychology ever written, it also marks a milestone in the development of Adorno’s thought, showing him grappling with the problem of fascism and the reasons for Europe’s turn to reaction. Over half a century later and with the rise of right-wing populism and the reemergence of the far-right in recent years, this hugely influential study remains as insightful and relevant as ever.

This new edition includes an introduction by Frankfurt School scholar Peter E. Gordon and contains the first-ever publication of Adorno’s subsequent critical notes on the project.
