This is a landmark study of the distinct form that psychological power has come to take in prison, despite being wielded by an insecure, beleaguered workforce. It is written with insight and imagination. The prison is a place of punishment, and yet it seeks to 'remake' the prisoner. The forensic psychologist has come to lie at the heart of this contradiction, largely serving the institutions' interests using a new, and flawed, 'disciplinary capital'. Jason Warr’s analysis of just how 'entangled with power' they have become is original, critical, and shrewd.
