1. The best Broadway shows were produced by networks with an intermediate level of social intimacy. The ideal level of Q—which Uzzi and his colleague Jarrett Spiro called the “bliss point”—emerged as being between 2.4 and 2.6. A show produced by a team whose Q was within this range was three times more likely to be a commercial success than a musical produced by a team with a score below 1.4 or above 3.2. It was also three times more likely to be lauded by the critics. “The best Broadway teams, by far, were those with a mix of relationships,” Uzzi says. “These teams had some old friends, but they also had newbies. This mixture meant that the artists could interact efficiently—they had a familiar structure to fall back on—but they also managed to incorporate some new ideas. They were comfortable with each other, but they weren’t too comfortable.
