Conscientious people are good at backing up other team members, and they’re also good at sensing when their support is truly needed. One study found that specific behavioral tendencies such as personal organization, cognitive structuring, achievement orientation, and endurance were all related to higher levels of team performance. Open team members communicate better with one another and throw out more ideas, which makes teams composed of open people more creative and innovative.
