Modeling and managing collective cognitive convergence

When the same people interact frequently, they come to think alike, a phenomenon we call "collective cognitive convergence" (C3). We discuss instances and practical consequences of this phenomenon; review previous work in sociology, computational social science, and evolutionary biology that sheds light on C3; define a computational model and metrics for the convergence process; report on experiments with this model and metrics; and suggest how insights from the model can help manage C3.
