IQ vs. EQ
In some teams, whilst individuals weren't necessarily those who had scored most highly for intelligence, they came up with ways to use each other's strengths. Some groups had strong leaders, whilst others were more fluid.
The researchers eventually concluded that – rather than intelligence – what separated high-performing teams from dysfunctional ones was how members of the team treated one another.
In working with teams at Henley Management College, Dr Belbin coined the term 'Apollo teams' for teams made up of high-intellect individuals who spent a lot of time engaged in abortive debate. In 'Management Teams: Why They Succeed or Fail', Dr Belbin comments that: 'The lack of coherent teamwork nullified the gains of individual effort or brilliance'.
So too in Google. Whilst the 'average intellect' teams didn’t appear to work so efficiently, their understanding of one another's moods and emotions helped establish trust and various other factors needed for success.
