In meetings and in group settings where people come together to collaborate, there is a strong sense of a group IQ, the sum total of intellectual knowledge and skills in the room. The most important element in a group's intelligence is not the average or highest IQ, but emotional intelligence. A single participant who is low in EQ can lower the collective IQ of the entire group. Robert Sternberg and Wendy Williams of Yale have studied this "group IQ."
Thus, a group may be able to work smarter than its members' collective intelligences would suggest, but it can also rapidly work dumber by not allowing people to share talents and by allowing destructive discontent, domineering, or infighting to degrade performance and stymie progress.
This has obvious impact on the effectiveness of teams and work groups. Today's fast-changing work environments require more open and fluid work styles. Teaming, in order to be effective, requires people to have a high degree of both intellect and EQ. People need to be able to handle their own and other's emotions in order to trust and team up for problem-solving and decision-making.
