I recently did a talk where the organizer set up the room in the round, with the stage in the middle. He proudly told me that it would create a sense of intimacy because more people would be close to the stage.
Of course, this isn't true. Physical proximity is one thing, but connection and intimacy come from eye contact, from hearing and being heard, from an exchange of hopes and dreams.
Cocktail parties involve too many people in too small a room, but they rarely create memorable interactions. And the digital world eliminates the barriers of space, supposedly enhancing our ability to make a connection.
Too often, though, we use that physical or digital proximity to push others away instead of to invite them in. We hesitate to lean in or to raise our hands. The speaker in the round has no choice but to turn her back to half the audience, no physical way to make eye contact and get a sense of what's happening. In the hundreds or thousands of interactions we have each day, proximity gives us the chance to connect, but it doesn't ensure it will happen.
That's up to us.
