A Scientific Basis for Rigor In Information Systems Research1
用逻辑学中的肯定前件和否定后件规则，分析了实证、解释、行动和设计四种研究范式，指出信息系统研究在科学基础、肯定后件谬误和总结效度三方面的问题，有助于提升研究的严谨性与相关性。
Qualitative research is just as able as quantitative research to follow certain fundamental principles of logic in general and scientific reasoning in particular. Two such principles are the logic of modus ponens and the logic of modus tollens. In this essay, we frame different research approaches— positivist research, interpretive research, action research, and design research—in the forms of modus ponens and modus tollens. Three issues emerge from this framing and call into question how research is now conducted in the discipline of information systems. They are the issue of a common scientific basis, the issue of the fallacy of affirming the consequent, and the issue of summative validity. Both rigor and relevance in information systems research may be better achieved by attending to the three issues.
