Research on sex differences in communication has produced mixed and contradictory results. An erroneous overlap exists between self reports of male-female behaviors, others' reports of perceived behaviors, and stereotyped projections based on social conditioning. The solution to this confusion in gender communication research may be triangulation, or the use of multiple and diverse data sources and collection techniques. Triangulation as a methodology for understanding the female experience holds promise because it encourages the convergence of traditional and non-traditional data by admitting multiple perspectives. The use of triangulation to compare males and females in organizations could help explain why male and female professionals who have similar backgrounds and exhibit similar preferences for leadership and leadership communication styles experience different rates of promotion within organizations. One example of a research design using triangulation compared male and female communication behaviors during decision making and determined how behaviors were evaluated in terms of effectiveness. Research instruments included self reports, collection of demographic and career data, personal interviews, videotaped decision making interactions, content analysis of the tapes, and evaluations by business professionals. Triangulation allowed for a more holistic evaluation of sex differences in communication. (An eight-page list of references is provided.) (SRT)
