Social network structure and the achievement of consensus

Politics, Philosophy & Economics, 2012, vol. 11, issue 1, 26-44

Abstract: It is widely believed that bringing parties with differing opinions together to discuss their differences will help both in securing consensus and also in ensuring that this consensus closely approximates the truth. This paper investigates this presumption using two mathematical and computer simulation models. Ultimately, these models show that increased contact can be useful in securing both consensus and truth, but it is not always beneficial in this way. This suggests one should not, without qualification, support policies which increase interpersonal contact if one seeks to improve the epistemic performance of groups.
