 Whether masses can be wise and should be entrusted with important decisions is a question with long philosophical pedigree. The Athenian democracy increased the decision body compared to its oligarchic competitors, demonstrating that such an enlargement can engender collective epistemic success (Ober 2008; 2013). Against this backdrop, the philosophical debate about the epistemic performance of democracy began. Aristotle, for instance, despite being generally sceptical of the rule by the people, concedes the possibility of group wisdom (Aristotle, Politics: 1281a11; Waldron 1995), though this reading is contested (Cammack 2013; Lane 2013).
