institution of higher learning, although some history departments have run courses in it. Psychohistory remains a controversial field of study, facing criticism in the academic community, with critics referring to it as a pseudoscience. Psychohistory uses a plurality of methodologies, and it is difficult to determine which is appropriate to use in each circumstance. Yet this "plurality" is quite circumscribed. In 1973, historian Hugh A. Trevor-Roper dismissed the field of psychohistory entirely in response to the publication of Walter Langer's The Mind of Adolf Hitler. He contended that psychohistory's methodology rested "on a defective philosophy" and was "vitiated by a defective method." Instead of using historical evidence to derive historical interpretations, Trevor-Roper contended that "psycho-historians move in the opposite direction. They deduce their facts from their theories; and this means, in effect, that facts are at the mercy of theory, selected and valued according to their consistence with theory, even invented to support theory." DeMause has received criticism on several levels. His formulations have been criticized for being insufficiently supported by credible research. He has also received criticism for being a strong proponent of the "black legend" view of childhood history (i.e. that the history of childhood was above all a history of progress, with children being far more often badly mistreated in the past). Similarly, his work has been called a history of child abuse, not childhood. The grim perspective of childhood history is known from other sources, e.g. Edward Shorter's The Making of the Modern Family and Lawrence Stone's The Family, Sex and Marriage in England 1500-1800. However, deMause received criticism for his repeated, detailed descriptions on childhood atrocities: The reader is doubtless already familiar with examples of these psychohistorical "abuses." There is a significant difference, however, between the well-meaning and serious, if perhaps simplistic and reductionistic, attempt to understand the psychological in history and the psychohistorical expose that can at times verge on historical pornography. For examples of the more frivolous and distasteful sort of psychohistory, see Journal of Psychohistory. For more serious and scholarly attempts to understand the psychological dimension of the past, see The Psychohistory Review. Recent psychohistory has also been criticized for being overly-entangled with DeMause, whose theories are not representative of the entire field. Organizations Boston University offers a Psychohistory course at the undergraduate level and has published course details. The Association for Psychohistory was founded by Lloyd deMause. It has 19 branches
