Any series of studies which attempt to deal with the problems of conflict and lack of communication among blacks and whites in job settings must logically include some empirical analysis of these conflicts. This paper uses an information content analysis of critical incident data. The critical incident methodology focuses on specific instances of behavior which provide positive or negative outcomes, attempting to give specific behavioral referents to positive or negative evaluations. Because it is both an exploratory technique and one which is tied to behavior, it is well suited for the generation of real-life conflicts which may then be used as stimuli in studies of training effectiveness. Critical incidents were collected from 11 black and 13 white workers from a number of Champaign and Urbana firms, by interviewers of the same race as the respondent. Workers were asked about incidents of conflict between themselves and members of the other race. To perform the content analyses, the authors first read the texts of all black and white respondents. A system of categories, based on the texts, was then devised separately for white and black subjects. Texts were numbered and checks were placed under each category name present in a given text. Categories and text codings represent the consensus of the authors. (Author/JM)
