I continue to be amazed in meetings where when people speak, few others actually give the presence of eye contact to them. In some groups this has become normatively acceptable practice exacerbated by the distractions of slides and things with screens. The phenomenon often grows in proportion to the size of the group. Most conversational meetings are not designed for authentic interaction. They are instead designed for speeches and other unilateral pronouncements and parries. Making matters worse, the non-renewable and expensive resource of time gets wasted on information that should otherwise be virtually available in real time for real action.
All of this is prevented with better designed meetings, regardless of the group size, diversity, scope of work or level of ambiguity and complexity the group encounters.
