The fervent debate over the last 100 years about quantitative and qualitative research paradigms has resulted in a great divide between quantitative and qualitative researchers, who often view themselves as in competition with each other. This polarization has promoted "uni-researchers," researchers who restrict themselves exclusively to either quantitative or qualitative research methods. A false dichotomy exists between quantitative and qualitative research, with all distinctions between the two methods lying on continua. Relying on only one type of data is extremely limiting, and "uni-research" is a threat to the advancement of the social sciences. This paper provides evidence that the debate between quantitative and qualitative methodologies is divisive and counterproductive for advancing the fields of the social and behavioral sciences. All graduate students should learn to use and appreciate both methodologies to develop into "bi-researchers." (Contains 1 figure and 48 references.) (SLD)
