The chief aim of this project is to capitalize on the range of disciplines within the sciences and philosophy that have made self-control a research focus by providing incentives and opportunities for collaboration among them. The goal of fostering this collaboration is to improve our knowledge of self-control and how to enhance it, in part by developing a more integrated and complete understanding of the topic. Similar collaboration among different kinds of scientists and philosophers has been a fruitful strategy with respect to other topics in recent years—witness, for example, the scientific and philosophical work on free will and moral judgment that has been produced by such collaboration—and the hope is that the project will lead to the same kind of progress. The central component of the project is a set of RFP competitions to support informed and collaborative research on self-control in science and philosophy. Other components include two conferences, a summer seminar, a cluster grant program, and a post-doctoral fellowship opportunity.
