Why some teams are smarter than others?

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

  1. Their members contributed more equally to the team’s discussions, rather than letting one or two people dominate the group.
  2. 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.
  3. 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.
