Conformity is an often criticized feature of human belief formation. Although generally regarded as a negative influence on reliability, it has not been widely studied. This paper attempts to determine the epistemic effects of conformity by analyzing a mathematical model of this behavior. In addition to investigating the effect of conformity on the reliability of individuals and groups, this paper attempts to determine the optimal structure for conformity. That is, supposing that conformity is inevitable, what is the best way for conformity effects to occur? The paper finds that in some contexts conformity effects are reliability inducing and, more surprisingly even when it is counterproductive, not all methods for reducing its effect are helpful. These conclusions contribute to a larger discussion in social epistemology regarding the effect of social behavior on individual reliability.

“…Most work in this area relies on classical models of interacting particle systems whose motivation comes from statistical mechanics (see [65] and references therein). In these models, opinions are represented by either finitely many discrete values (as in the Ising model, introduced by Glauber [48] and the voter model, introduced independently by Clifford and Sudbury [23] and by Holley and Liggett [60]), or continuous values (as in the DeGroot model [28] and the bounded confidence models of Krause [63] (further developed by Hegselmann and Krause [59], Deffuant, Neau, Amblard and Weisbuch [27] and Weisbuch, Kirman and Herreiner [93])). The opinions of the agent evolve dynamically over time as a function of their neighbors' opinions.…”
“…Spins present agents with different opinions in Ising model. Based on the Ising model, a number of classic public opinion evolution models start to emerge, that include voter model [4], Sznajd model [5], majority rule model [6][7][8], social impact theory [9], bounded confidence models [10][11][12], CODA model [13][14][15][16], and the gambling model [17,18]. These models simulate the process and final results of public opinion evolution.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
