Research on group recommender systems (GRS) has yielded innovative concepts for suggesting services or products to groups of users as well as for bringing users with similar tastes together. We have developed such concepts for group recommender systems and a platform in the domain of movie recommendations for groups. In this workshop we argue that putting a stronger focus on the evolution of the group negotiation process as well as social psychological concepts in the respective decision phase can increase the usability of GRS.
