Why Some Teams Are Smarter Than Others: Have more women on the team
An argument for diversity is that it leads to better team decisions and designs. But it turns out that having women on the team at all leads to better group performance. It’s an important finding to argue why we need more women in CS, which is still a question I hear regularly, “So what if almost all our undergraduates are women?” Or as one blogger recently put it (see here if you really want to read more of this), “No one in the tech sector right now gives a shit about diversity. There is no reason whatsoever why a lack of diversity in the field would be a problem unless it comes from government quotas and legal threats.”
Instead, 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.
