 Zollman (2007, 2010) describes what has now been dubbed the “Zollman effect” in these models; the surprising observation that it is sometimes worse for communities to communicate more (see also, Grim 2009). In particular, groups with more network connections will be generically less likely to arrive at a correct consensus. The group needs to entertain all the possible options long enough to gather good evidence and settle on the best one. In tightly connected networks, misleading evidence is widely shared, and may cause the community to pre-emptively settle on a poor theory.
