Dissonance Minimization and Conversation in Social Networks
We study a model of social learning in networks where the dynamics of beliefs are driven by conversations of dissonance-minimizing agents. Given their current beliefs, agents make statements, tune them to the statements of their associates, and then revise their beliefs on the basis of those statements. We fully characterize the long-run beliefs in a society, provide the necessary and sufficient conditions for a society to reach a consensus, and show that agents’ social influences (weights on the consensus belief) are decreasing in their dissonance sensitivities. We also highlight the role of conversation by comparing the outcomes of two models, with and without conversation, and show that conversation leads to a redistribution of social influences in favor of agents with higher self-confidence. We end by providing some analytical insights for the model where agents minimize dissonance by revising both beliefs and network, and show that an endogenous change of network may prevent a society from reaching a consensus
