Malthus's Essay on Population: the facts of "super-growth" and the rhetoric of scientific persuasion

For the Malthusian theory of population to be accepted as "scientific," it was essential that the theory be established on wide empirical evidence. A close examination of the "facts" provided by Malthus, however, shows that many of his crucial facts are based on distortions of the available evidence. Malthus was probably aware of much of this weakness, but for rhetorical reasons he persisted with the sandy empirical foundations from which he began.     

Margaret Mead and behavioral scientists in World War II: problems in responsibility, truth, and effectiveness

In World War II, Margaret Mead and her behavioral science colleagues actively applied their science to the American war effort on issues such as morale, food habits, psychological warfare, and the evacuation of Japanese-Americans from the West Coast. Mead's participation or lack of participation in these activities, and her varying enthusiasms and misgivings about them, raise fundamental issues about the responsibility of behavioral scientists to warn the public against dangerous policies, as well as the ethics of behavioral scientists participating in deceitful psychological warfare and the extent of their effectiveness in contributing to public policymaking.     

In Hall's shadow: Edmund Clark Sanford (1859-1924)

Edmund C. Sanford of Clark University had earned a reputation by the end of the nineteenth century as a leading American psychologist. He had written the first training manual for experimental psychology and created numerous pieces of laboratory apparatus. He was also editor of the American Journal of Psychology and a charter member of the American Psychological Association. Although his peers elected him to the presidency of the APA in 1902, his standing had already begun to decline. Sanford's impact on early American experimental psychology is documented and the reasons for his reduced status as American psychology grew in the early years of the new century are explored.     

Leadership skills and helpful factors in self-help groups

The effects of training on leadership skills and group processes in cancer and anorexic self-help groups are investigated. Three components of the study are reported. Firstly, an observational case-study of each type, of group was conducted to investigate the nature of the leadership input. Secondly, a Self-Help Questionnaire based on Lieberman's classification of leadership skills was administered to members of eight self-help groups to compare the experiences of groups with trained and untrained leaders. Thirdly, group members completed a Helpful Factors Questionnaire based on Yalom's analysis of group processes. The observational case-study revealed significant differences between the trained and untrained leaders in that, unlike the trained leader, the untrained leader clearly dominated the group. Results from the Self-Help Questionnaire showed that trained leaders scored higher on Caring and Emotional Stimulation but lower on Attribution of Meaning. Member satisfaction, however, was similar in the two types of group. Results from the Helpful Factors Questionnaire showed that most of the helpful factors were seen similarly by the two types of group, though differences were found concerning the relative rankings of both Guidance and Altruism. It is concluded that some degree of training of group leaders could be usefully incorporated into the self-help movement.
