“Unexpectedly, we found that the factors most people usually think of as driving group performance—i.e., cohesion, motivation, and satisfaction—were not statistically significant. The largest factor in predicting group intelligence was the equality of conversational turn taking; groups where a few people dominated the conversation were less collectively intelligent than those with a more equal distribution of conversational turn taking. The second most important factor was the social intelligence of a group’s members, as measured by their ability to read each other’s social signals. Women tend to do better at reading social signals, so groups with more women tended to do better (see the Social Signals Special Topic Box [at the end of Chapter 7]).”
