This article assesses the value of Karl Popper's situational analysis for contem porary sociology We maintain that this element of Popper's social science methodology has been largely neglected by sociologists and suggest that this is because it is borrowed from economics. As such, situational analysis has much in common with recent attempts to introduce rational choice in sociology. Our main question is this: What is the contribution of situational analysis to the current debate about rational choice in sociology? Our answer (...) is that Popper has little to add to this debate. His formulation of situational analysis is too general and too vague to be much of a guide to research. Among other things, situational analysis fails to pay due attention to interests and to social interaction in the explanation of social phenomena. On the positive side, we notice that Popper does include social institutions as the most important element in individuals' situations. (shrink)

The Rationality Principle says that people act adequately to their situation, but does not specify how they must act in order to do so. Situational Analysis uses the Rationality Principle, together with a model of the social situation, to explain actions in the past. Unlike Rational Choice Theory, Situational Analysis does not try to predict or influence actions in the future. Popper regarded the Rationality Principle as false, but thought that we should use it nonetheless. This poses a problem for (...) understanding his views about conjecture and refutation. Popper, however, thought that all scientific models are false, and that whether or not we should reject a model depends on the problem that we are trying to solve. (shrink)

Popper holds to the unity of scientific method: any differences between natural and social science are a product of theory, not a pretheoretical premise. Distin guishing instead pure and applied generalizing sciences, Popper focuses on the different role of laws in each. In generalizing social science, our tools are the logic of the situation, including the rationality principle, and unintended conse quences. Situations contain individuals, but also social entities not reducible to individuals: conspiracy theory is the extreme form of individualism. (...) Action in situations has unintended consequences. Both social and natural laws may be required to explain outcomes. The fate of Popper's ideas is a case study in the logic of the situation. Professional philosophers of social science lean toward individualism and a priorism (either intuitionist or rational choice). There are social and political explanations of this outcome, but little critical engagement with Popper's ideas. (shrink)
