Between fitting in and belonging
Fitting in comes at the cost of conformity. When we leave an open space for constructive misunderstanding, we can energize containers to take on a not-yet-known (and often more creative) direction of thinking.
More tactically, when a group of people meets to achieve a particular goal, fitting in is inevitable: we need to delegate, assign or assume roles, and reach a standard finish line.
I deposit that this process is not binary, and there are a few (or many) steps on the ways to create alignment. Rushing to alignment too early (/say with immediate introductions) has dire consequences for individual creativity and the container's energy level.
