Information processing in groups has long been seen as a cooperative process. In contrast with this assumption, group members were rarely found to behave cooperatively: They withhold unshared information
and stick to initial incorrect decisions. In the present article, we examined how group members' cooperative
and competitivemotives impact on group information processing and propose that information sharing
and use in groups could be seen as strategic behavior. We reviewed the latest developments in the
literature investigating different forms of strategic information processing and their underlying mechanisms.
This review suggests that explicit cooperative goals are needed for effective group decision-making.
