Decisions, Groups and Networks (8-9 September 2014)


Idea and Motivation

In recent years, formal and empirical approaches have become central to study decision-making. Social network analysis, agent-based modeling and simulation techniques are meanwhile widely used not only in sociology, political science, social psychology, and economics. Also philosophers increasingly point to the potentials of these approaches for addressing questions in political and moral philosophy, formal epistemology, and philosophy of science more generally. Whereas the importance of social dynamics and network structures for investigating into decision-making has been largely acknowledged, the application and results of these novel approaches raise a number of philosophical issues that have not yet been discussed in the literature. This workshop will bring together social scientists, philosophers, decision theorists, and psychologists to explore and discuss the potentials and limitations of these approaches for scientific practice and philosophy alike.
