Pragmatism allows for the integration of qualitative and quantitative methods as loosely coupled systems to support mixed methods research. On the one hand, quantitative research is characterized by randomized controlled trials, research questions inspired by literature review gap, generalizability, validity, and reliability. On the other, qualitative research is characterized by socially constructed realities and lived experiences. Pragmatism reconciles these differences an integrates quantitative and qualitative research as loosely coupled systems, where "open systems interact with each other at the point of their boundaries."
History of Pragmatism in Multi/Mixed Methods Research Developed as a philosophical method to solve problems towards the end of the nineteenth century, pragmatism is attributed to the work of philosopher
Charles Sanders Peirce. For Peirce, research is conducted and interpreted from the eye of the beholder, as a practical approach to investigating social affairs. He sees science as a communal affair leading to single truths that are arrived at from multiple perspectives. For Peirce, the research conclusions are not as important as how these conclusions are reached. Focus is on answering the research question while allowing the methods to emerge in the process. Peirce pragmatism and its approach to research support qualitatively driven mixed methods studies.
John Dewey extends both, "Peirce pragmatic method and (William) James' radical empiricism (and approach to experience) by application to social and political problems." His philosophical pragmatism takes an interdisciplinary approach, where the divide between quantitative and qualitative research represents an obstacle to solving a problem. In Dewey's pragmatism, success is measured by the outcome, where the outcome is the reason to engage in research. Live experiences constitute reality, were individual lived experiences form a continuum by the interaction of subjective (internal) and objective (external) conditions. In Dewey's continuum of experiences, no experience lives on its own, it is influenced by the experiences that preceded it, and influences those that will follow it. His approach to knowledge is open-minded, and inquire is central to his epistemology. Following Dewey, quantitatively driven research methods dominated until 1979, when Richard Rorty revived pragmatism. Rorty introduces his own ideas into pragmatism which includes the importance of culture, beliefs, and context. He shifts from understanding how things are to how they could be, and introduces the idea that "justification is audience dependent, and pretty much any justification finds a receptive audience" As Rorty explains, research success is peer dependent, not peer group neutral. From his perspective, MMR is not simply the merging of quantitative and qualitative research, but a third camp with its own peers and supporters.
Pragmatic philosophical positions Multiple pragmatic philosophical stands may be used to justify pragmatism as a paradigm when conducting mixed methods research (MMR). A research paradigm provides a framework based on what constitutes and how knowledge is formed. Pragmatism as a philosophy may aid researchers in positioning themselves somewhere in the spectrum between qualitatively driven and quantitatively driven methods. The following philosophical stands can help address the debate between the use of qualitative and quantitative methods, and to ground quantitatively, qualitatively, or equal-status driven MMR.
Radical empiricism Radical empiricism, as articulated by
William James, takes reality as a function of our ongoing experiences, constantly changing at the individual level. James emphasizes that reality is not predetermined, and individual free will and chance matter. These ideas fit well with qualitative research emphasizing lived experiences. James also finds the truth in empirical and objectives facts, merging the divide between qualitative and quantitative research. However, James points out that no truth is independent of the thinker. James' brand of pragmatism may be used by researchers conducting qualitatively and equal-status driven MMR.
Dialectical Pluralism Dialectical pluralism is a form of pragmatism that emphasizes intentionally drawing from multiple approaches to conducting research and developing knowledge. The multiple approaches being taken need not agree or converge with one another. Instead, the researcher using dialectical pluralism in the conduct of a mixed-method study may tack back and forth between models and perspectives in order to develop insight.
Realism and Critical Realism Realists and critical realists take the perspective that the world exists independently of our observation and interpretation of it; critical realism goes beyond this to assert that multiple interpretations of the world are likely. Like dialectical pluralism, realist paradigms in the context of pragmatic multi/mixed-methods research emphasize the idea that multiple approaches to knowledge are expected and can be treated as complementary. In contrast to a more strict
positivist approach, critical realism sees
causality as embedded in the details of a situation and social processes that surround an event.
Transformative-Emancipatory Transformative and emancipatory paradigms emphasize a commitment on the part of the researcher to social justice, as in
critical race theory. Researchers conducting multi-method or mixed-methods research within this paradigm tend to orient to issues of "power, privilege, and inequity." ==In contrast to quantitative and qualitative methodologies==
