A new study shows that for problem solving, two heads are usually better than one, unless any involved are incompetent and incapable of admitting it:

 If one person in the team has flawed information -- or is less competent -- then the outcome can be negative and perhaps you should completely ignore them...

Bahrami’s study tells us that what’s important for successful collaboration is the ability to estimate and report our own ability accurately. However, this is not always easy, especially for incompetent individuals. In psychology, there is a known cognitive fallacy called the Dunning-Kruger effect. The most incompetent individuals often overestimate their skills and think they are all above average, though that’s logically impossible. Having such a person in your team would severely damage performance. Simply put, if you are not sure about your competency in a team, the most productive thing to do is to tell your team members -- though in reality, of course, this is not easy.
