…the smartest teams were distinguished by three characteristics.
First, their members contributed more equally to the team’s discussions, rather than letting one or two people dominate the group.
Second, their members scored higher on a test called Reading the Mind in the Eyes, which measures how well people can read complex emotional states from images of faces with only the eyes visible.
Finally, teams with more women outperformed teams with more men. Indeed, it appeared that it was not “diversity” (having equal numbers of men and women) that mattered for a team’s intelligence, but simply having more women. This last effect, however, was partly explained by the fact that women, on average, were better at “mindreading” than men.
…This last finding was another surprise. Emotion-reading mattered just as much for the online teams whose members could not see one another as for the teams that worked face to face. What makes teams smart must be not just the ability to read facial expressions, but a more general ability, known as “Theory of Mind,” to consider and keep track of what other people feel, know and believe.
A new science of effective teamwork is vital not only because teams do so many important things in society, but also because so many teams operate over long periods of time, confronting an ever-widening array of tasks and problems that may be much different from the ones they were initially convened to solve.
General intelligence, whether in individuals or teams, is especially crucial for explaining who will do best in novel situations or ones that require learning and adaptation to changing circumstances. We hope that understanding what makes groups smart will help organizations and leaders in all fields create and manage teams more effectively.
