Common Knowledge, Coordination, and Strategic Mentalizing in Human Social Life
By: Julian De Freitas, Kyle A. Thomas, Peter DiScioli and Steven Pinker
Abstract
People often coordinate for mutual gain, such as keeping to opposite
sides of a stairway, dubbing an object or place with a name, or
assembling en masse to protest a regime. Because successful coordination requires complementary choices, these opportunities raise
the puzzle of how people attain the common knowledge that
facilitates coordination, in which a person knows X, knows that
the other knows X, knows that the other knows that he knows, ad
infinitum. We show that people are highly sensitive to the distinction
between common knowledge and mere private or shared knowledge, and that they deploy this distinction strategically in diverse
social situations that have the structure of coordination games,
including market cooperation, innuendo, bystander intervention,
attributions of charitability, self-conscious emotions, and moral
condemnation.
