Concept
Postpositivism
Summary
Postpositivism or postempiricism is a metatheoretical stance that critiques and amends positivism and has impacted theories and practices across philosophy, social sciences, and various models of scientific inquiry. While positivists emphasize independence between the researcher and the researched person (or object), postpositivists argue that theories, hypotheses, background knowledge and values of the researcher can influence what is observed. Postpositivists pursue objectivity by recognizing the possible effects of biases. While positivists emphasize quantitative methods, postpositivists consider both quantitative and qualitative methods to be valid approaches.
Postpositivists believe that human knowledge is based not on a priori assessments from an objective individual, but rather upon human conjectures. As human knowledge is thus unavoidably conjectural, the assertion of these conjectures are warranted, or more specifically, justified by a set of warrants, which can be modified or withdrawn in the light of further investigation. However, postpositivism is not a form of relativism, and generally retains the idea of objective truth.
Postpositivists believe that a reality exists, but, unlike positivists, they believe reality can be known only imperfectly. Postpositivists also draw from social constructionism in forming their understanding and definition of reality.
While positivists believe that research is or can be value-free or value-neutral, postpositivists take the position that bias is undesired but inevitable, and therefore the investigator must work to detect and try to correct it. Postpositivists work to understand how their axiology (i.e. values and beliefs) may have influenced their research, including through their choice of measures, populations, questions, and definitions, as well as through their interpretation and analysis of their work.
