A recent study at Carnegie Mellon revealed the value of group intelligence as well as some information on how to improve your group's effectiveness:Surprisingly to Dr. Woolley, the average IQ of a group had almost no impact on its collective intelligence. It also didn't matter whether a group had one high-IQ individual.
There were three factors that did make a difference, though.
One was the social sensitivity of group members -- how much they paid attention to each other and asked questions.
The second was turn-taking. Groups that shared the floor had much better results. "When you had someone really dominating the conversations in these groups, the group did not perform well," she said.
Finally, in general, the more women in a group, the smarter it was.
As they analyzed that result, she said, it didn't mean the women had higher IQs than the men, but that they were more socially sensitive and less likely to dominate discussions.
