This chapter proposes a solution, based on the theory of social networks, to the problem of weight assignment in the Lehrer-Wagner model for consensus. The Lehrer-Wagner model of consensus is introduced, and the problem of weight assignment is outlined, together with a number of possible solutions previously suggested in the literature. The chapter argues that there is no one-size-fits-all solution to the problem of weight assignment in the Lehrer-Wagner model, and suggests an alternative solution, which is based on the idea of deriving weights from existing networks of relations in the group. This proposal, it is argued, is particularly useful for maximizing or limiting the influence of a network of relations on the consensual opinion resulting from the model.
