Groups are smarter than individuals – two heads are usually better than one.
However, team meetings usually default to one or two voices dominating them. Meetings are also prone to group-think, where other people end up echoing whoever is loudest or the most insistent. All of this exacts a cost on group intelligence.
As leaders, it is our responsibility to design our meetings in a manner that we harness the wisdom of the crowd rather than settle for the wisdom of the loud.
