This article considers the opposition between the pluralist and unificationist stances in the philosophy of cognitive sciences. The choice between pluralism and unificationism is important both in terms of discussing the current methodological practices and with respect to the debates about the future of the cognitive studies. As a starting point, the author takes his own idea of theoretical complexes. One of its most significant normative consequences is theoretical pluralism. There have been a number of skeptical arguments against pluralism, including (...) the fear of generating many useless theories and dissipating of efforts, as well as the doubts about the differences between pluralism and relativism. One of the most recent objections states that integrative pluralism implies a tension, an instability, if one prioritizes the epistemic quality of explanatory depth. The author addresses each of these objections in turn. The constructive variety of pluralism is distinguished from unbridled pluralism and relativism by its commitment to the idea of improving explanatory, predictive, and other characteristics of a theory through the presence of alternatives and their collisions, mutual criticisms. Integrative pluralism does not entail instability, since the values of unification and explanatory depth cannot be prescribed to the cognitive sciences ex cathedra, without taking into account the character of the cognitive process revealed in empirical studies. The pluralist stance appears to be incompatible with radical projects of unification of the cognitive studies, though there are many opportunities for more moderate integrative initiatives. One such initiative is the recent idea of integrative experiment design, which involves constructing a space of experiments for a particular problem. Testing theories by selectively sampling points in this space and then updating them accordingly may be a key to the integration of experimental observations. (shrink)

In light of the recent credibility crisis in psychology, this paper argues for a greater emphasis on theorizing in scientific research. Although reliable experimental evidence, preregistration, methodological rigor, and new computational frameworks for modeling are important, scientific progress also relies on properly functioning theories. However, the current understanding of the role of theorizing in psychology is lacking, which may lead to future crises. Theories should not be viewed as mere speculations or simple inductive generalizations. To address this issue, the author (...) introduces a framework called “cognitive metascience,” which studies the processes and results of evaluating scientific practice. This study should proceed both qualitatively, as in traditional science and technology studies and cognitive science, and quantitatively, by analyzing scientific discourse using language technology. By analyzing theories as cognitive artifacts that support cognitive tasks, this paper aims to shed more light on their nature. This perspective reveals that multiple distinct theories serve entirely different roles, and studying these roles, along with their epistemic vices and virtues, can provide insight into how theorizing should proceed. The author urges a change in research culture to appreciate the variety of distinct theories and to systematically advance scientific progress. . (shrink)
