This paper argues that the group’s task is the most neglected moderator in group research. After offering a broad conception of group task, I draw on various sources to illustrate the powerful moderating role of group task and the field’s broad neglect of this moderation. I conclude with some suggestions for how we might better acknowledge and address the importance of group task for group behavior.
