In leader centric meetings, the leader invites individuals to interact one-on-one with the leader. If this pattern becomes established enough, people can grow to feel that peer dialogue is a violation of the hub-and-spoke centrality of leader. Leader centric meetings have the power to keep groups weak and less likely to grow. Some leaders strongly prefer this because it effectively maintains their unilateral dominant power over others. In group centric meetings, the leader does everything she or he can to stimulate and foster peer to peer interactions. These leaders work instead from the principles that people are smarter together and that strong groups are the highest performing groups.
