"What makes teams smart is a general ability, known as “Theory of Mind,” to consider & keep track of what other people feel, know & believe"
- 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.
