Two Heads Are Better Than One

Many of us grew up hearing the expression, two heads are better than one. On an intuitive level, this idiom makes sense: you get better results when you invite another person’s perspective to assess a situation, help solve a complex problem, or come up with a new approach. This is especially true when the stakes are high, so why go it alone?

Research now supports this idea. Professor Chris Frith of University College London (UCL) found this to be the case when the people involved are relatively competent and able to embrace opposition. In other words, they must be able to respectfully disagree while continuing to move toward a desired outcome. In one experiment, this proved to be true even when one participant had far greater experience and more facts. In short, two heads are better when the people involved can successfully navigate opposing perspectives.

If two heads are better than one under these conditions, then what about three, five or even ten people working together to accomplish something important? Is it safe to assume that many heads addressing a tough problem is an even better approach? That seems to be what Dr. Anita Woolley’s team at the MIT Center for Collective Intelligence found as they measured the collective intelligence of groups. Their findings suggest that groups are collectively more intelligent when members are socially sensitive and allow everyone on the team to contribute their ideas. Diversity is also a contributor to collective intelligence—especially when there are more women on the team.

It’s hard to argue with science. The big question is, how do you develop your team’s skills to leverage the benefits of collective intelligence and the two heads phenomenon? Here are four practical skills that lead to better results:

Successful teams welcome different perspectives. Where teams struggle, only a few voices are heard. Fortunately, you can develop the skills that allow everyone to work better together and accomplish truly great results. When you do, two heads—or several—will be better than one.
