Why Some Teams Are Smarter Than Others

HughPickens.com writes Everyone who is part of an organization — a company, a nonprofit, a condo board — has experienced the pathologies that can occur when human beings try to work together in groups. Now the NYT reports on recent research on why some groups, like some people, are reliably smarter than others. In one study, researchers grouped 697 volunteer participants into teams of two to five members. Each team worked together to complete a series of short tasks, which were selected to represent the varied kinds of problems that groups are called upon to solve in the real world. One task involved logical analysis, another brainstorming; others emphasized coordination, planning and moral reasoning. Teams with higher average I.Q.s didn't score much higher on collective intelligence tasks than did teams with lower average I.Q.s. Nor did teams with more extroverted people, or teams whose members reported feeling more motivated to contribute to their group's success. Instead, the smartest teams were distinguished by three characteristics (PDF). 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. 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.

Interestingly enough, a second study has now replicated the these findings for teams that worked together online communicating purely by typing messages into a browser . "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."

  1. Imagine if having more men increased a team's by Anonymous Coward · · Score: 5, Insightful

    intelligence. The study would not be publishable.

  2. I have grown skeptical of these experiments. by 140Mandak262Jamuna · · Score: 5, Insightful
    It all sounds sciency enough but I have grown very disenchanted with these experiments that use "simple tasks" to judge "$parameter". As my company switched to Agile I was forced to undergo "Agile for managers" or whatever. They made senior manager stuff envelopes and place stamps and had a few gotchas. It made me realize the root of the con game is to pick the tasks that are so simple any team member could do it. The variability in skill set, the varieties of skills needed to complete the project is not fully addressed.

    Instead of some simple tasks which anyone can do, if we throw in some tasks that could only be done by one or two persons in the team, then it would be more realistic. Something like some step needs derivative of a function and only one team member remembers calculus 101, or requires translating a passage from French to English.. The moment you introduce variation in skill sets among the team members, agile for software breaks down. This experiment too might have different results.

    No it doesn't sound arrogant, it sounds defensive and most of all stupid. Stupid because you are missing the whole point, the article is not about who is better, it is about what is needed to make a good team. And yes teams are important, not just for your stupid examples. More generally there is a need for organization, you can't just let people do their thing in their corner and hope that you get everything you need. So there is a need for "smart" people and a need for "social" people, we need various qualities to achieve things.
