Efforts are everywhere! We make efforts to lift heavy weights, to concentrate, to stop smoking, to stay calm, to understand others, to win games, etc. But we don't yet know what efforts are, or what their value is, and we lack a general theory of efforts that can be used in the disciplines that study it (psychology, economics, sociology, law, and philosophy). The Effort Project investigates the nature and value of efforts.

The project is funded by the Swiss National Foundation, and led by Olivier Massin at the University of Neuchâtel’s Institute of Philosophy, in Switzerland.
