- because joining a minority has a greater cost to an individual than staying with a majority, the degree of commitment could persuade majority members to take them seriously or convert
- participants discussed the amount of compensation to be paid to someone involved in an accident
- when a confed put forward an alternative view and refused to change his position, it had no effect on the group members

however: influence was only evident in those who shifted view later in negotiations (seen as flexible) rather than those who shifted view earlier (seeming as caving in to the majority)
