Individual and Collective Agency, Intentionality & Rationality




Our research aims at understanding the cognitive underpinnings of individual and collective action and the relationships between individual and collective agency processes. Our perspective is interdisciplinary and combines approaches from philosophy, cognitive science, economics and psychopathology.

At present, we are particularly interested in the following sets of empirical and conceptual issues:

The cognitive infrastructure of shared intentionality: How do the cognitive processes and structures involved in joint action relate to those involved in individual action? How should the notions of shared intentionality, collective perspective and we-mode be characterized? Does empirical evidence support the idea of irreducible we-mode processes?

Coordination processes and their interplay: How do top-down and bottom-up coordination processes interact to align agent’s intentions and action so as to yield successful joint action? What role do conventions, social norms and commitments play in fostering coordination? How do those processes and devices connect up to relevant equilibrium notions in dynamic game-theory?

Choice-models: what are the mechanisms at work in individual and collective choice and how should we model them?
• Phenomenology of action: What are the relations and differences between the respective mechanisms underlying our experience of agency in individual and in joint action? Could our experience of agency for joint action be not just quantitatively but also qualitatively different from our experience of individual agency?

Decision environments: How do individuals and groups of individuals, small or large (societies), represent and adapt to the environments in which they make their decisions? How could environments be designed and individual and collective choice mechanisms implemented so as to maximize cognitive adequacy between decisions and their contexts?
