Many of the world's biggest problems are being tackled through the formation of new groups yet very little research has directly observed the processes by which new groups form to respond to social problems. The current paper draws on seminal research by Lewin (1947) to advance a perspective as to how such identities form through processes of small group interaction. Multi-level structural equation modelling involving 58 small group discussions (with N = 234) demonstrates that focused group discussion can boost the commitment to take collective action, beliefs in the efficacy of that action and members' social identification with other supporters of the cause. The results are consistent with the new commitment to action flowing from emergent social identities.Keywords: Social identity formation, small group interaction, collective action.

Group Interaction as the Crucible of Social Identity Formation: A Glimpse at the
Foundations of Social Identities for Collective ActionIn order to effect large scale social change we clearly need to do more than focus individual minds on the future. Instead, we need large sections of the public to embrace sustainable solutions collectively. To promote collective action of this kind, we need to fuse individual orientations toward the future with social identities that have the capacity to engender and sustain positive action. (Postmes, Rabinovich, Morton, & van Zomeren, 2012, p.194) The field of social psychology is filled with research on attitude change, prejudice, self-concept formation, stereotyping, and emotions, most of which has ignored how these processes operate in small groups. This neglect means that many questions central to the human social experience have not been investigated. (Wittenbaum & Moreland, 2008, p.188) In 1947 Kurt Lewin, one of the founders of modern social psychology, published findings of research into what he termed 'group decision'. Charged with the task of finding ways to change attitudes towards serving offal as a family meal as part of the World War II effort, Lewin compared the effects of listening to a lecture, with the effects of group discussion on samples of women who made food purchasing decisions for their families. The findings were striking. Of the women who had listened to the lecture, only 3% went on to prepare offal. Conversely, of those who had participated in a group discussion (about difficulties facing women in serving offal), 32% subsequently served offal to their families. Lewin (1958, p.202) concluded that "discussion, if conducted correctly, is likely to lead to a much higher degree of involvement".

4The legacies of this study were twofold. Lewin was the first to demonstrate the powerful effects of group interaction on changing attitudes and behaviour, findings that were mirrored some years later with the advent of the group polarization phenomenon (Moscovici & Zavalloni, 1969;Myers & Bishop, 1970). Lewin (1947, p. 150) was als...
