Moves it sheds light on
Our reading. None of these fields tests a move inside a circle.
The members’ bond with one another and the group, often called cohesion, is the field’s central measure.
Encounter groups and T-groups ran on members telling each other how they come across; the studies measured gains and harms.
Leaders’ styles shaped who was harmed in the Stanford groups; whether a leader who also takes part is safer hasn’t been tested.
