The slogan "study the victimizers, not the victims," can too easily become an excuse for substituting the ideologies and preconceptions of white and black intellectuals for the often different reality revealed by empirical research. This monograph tries to present a modest but complex set of data gathered using attitude sample survey methods, and to do so within a relatively objective framework of analysis and reporting. The main final comparison samples were representative of Detroit black heads and wives of heads of house, ages 21-69 inclusive, at each of three points in time. The first set of data is drawn from interviews with 2,809 black respondents, ages 16-69, in Detroit and 14 other American cities. These interviews were carried out between January 6 and March 31 of 1968. A second independent survey of black attitudes was carried out in Detroit by the Detroit Area Study April 24-July 31 of 1968. It included six questions from the first study. Because the assassination of Martin Luther King occurred during the three weeks between the completion of the first study and the beginning of the second, a comparison of responses to the six repeated questions permits assessment of the immediate effect of the assassination on attitudes of the Detroit black adult population. The third survey, also a Detroit area study, was carried out in 1971, April 15-September 26. (Author/JM)
