“…Available empirical evidence supports this approach: indeed a dataset of the advice network of judges, collected at three points in time (2000, 2002 and 2005), reveals a correlation between network structure, formal hierarchy of the institution (in particular, its division into Chambers, annual rotation of members across Chambers, rules of attribution of senior management roles) and normative views, which could hardly result from random matching; Rouchier & Tubaro (2011) show that an agent-based simulation based on Deffuant's model and modified to include membership turnover, but still assuming randomness in the formation of inter-personal ties, does not fit the data well. Instead, other factors are found to play a role in network tie formation, notably seniority and the internal hierarchy of the institution, as well as homophily, including opinion homophily (Lazega, Lemercier & Mounier 2006;Lazega, Mounier & Tubaro 2011;Lazega, Mounier, Snijders & Tubaro 2012). …”
