Over millennia, humans have invented various forms of social organization to govern themselves, ranging from tribes and clubs, to technocracies and democracies. These institutions enabled us to scale up our ability to coordinate, cooperate, exchange information, and make decisions. Today, instant connectivity, online social networks, pervasive algorithms, crowdsourcing, and big data can help us improve our existing cooperative institutions. More significantly, however, these technologies invite us to reimagine completely the ways in which we organize, cooperate, and govern. Our group aims to (1) understand how technology is reshaping the nature of human cooperation; and (2) imagine and design radically new ways of scaling up cooperation.
