[The] goal was to identify the salient features that made some teams much better than others. What they found was that individual intelligence (as measured by IQ) didn’t make the big difference. Having a high aggregate intelligence or just one or two superstars wasn’t critical. The groups that surfaced more and better solutions shared three key qualities. First, they gave one another roughly equal time to talk. This wasn’t monitored or regulated, but no one in these high-achieving groups dominated or was a passenger. Everyone contributed and nothing any one person said was wasted. The second quality of the successful groups was social sensitivity: these individuals were more tuned in to one another, to subtle shifts in mood and demeanor. They scored more highly on a test called Reading the Mind in the Eyes, which is broadly considered a test for empathy. These groups were socially alert to one another’s needs. And the third distinguishing feature was that the best groups included more women, perhaps because that made them more diverse, or because women tend to score more highly on tests for empathy. What this (and much more) research highlights is just how critical the role of social connectedness can be.
