 TJ researchers and practitioners typically make use of social science methods and data to study the extent to which a legal rule or practice affects the psychological well-being of the people it affects, and then explore ways in which anti-therapeutic consequences can be reduced, and therapeutic consequences enhanced, without breaching due process requirements.The term was first used by Professor David Wexler, of the University of Arizona Rogers College of Law and University of Puerto Rico School of Law, in a paper delivered to the National Institute of Mental Health in 1987.Constance Backhouse, a leading legal historian from Canada, has published a biography of Wexler and his work.
