The researchers concluded that extroverts could potentially be a "liability" on these missions.
Extroverts and teams NASA is interested in a number of issues related to planning long-term space missions, including how to put together the most compatible teams for the missions.
In the new study, which is funded by NASA, Bell and her colleagues reviewed previous research on teams who lived in environments similar to those of a long-term space mission, including simulated spacecraft missions of more than 100 days, as well as missions in Antarctica.
Typically, extroverts- who tend to be sociable, outgoing, energetic and assertive - are good to have on work teams because they speak up and engage in conversations about what needs to be done, which is good for planning, Bell said. And because of their social interactions, extroverts tend to have a good understanding of who knows what on a team (such as who the experts in a certain field are), which helps foster coordination.
But the researchers found several potential drawbacks to having extroverts on teams in isolated, confined environments.
