Empirical evidence on contemporary torture is sparse. The archives of the Spanish Inquisition* provide a detailed historical source of quantitative and qualitative information about interrogational torture. The inquisition tortured brutally and systematically, willing to torment all who it deemed as withholding evidence. This torture yielded information that was often reliable: witnesses in the torture chamber and witnesses that were not tortured provided corresponding information about collaborators, locations, events, and practices. Nonetheless, inquisitors treated the results of interrogations in the torture chamber with scepticism. This bureaucratized torture stands in stark contrast to the “ticking bomb” philosophy that has motivated US torture policy in the aftermath of 9/11. Evidence from the archives of the Spanish Inquisition suggests torture affords no middle ground: one cannot improvise quick, amateurish, and half-hearted torture sessions, motivated by anger and fear, and hope to extract reliable intelligence.
