For over 20 years, political influential Israelis and Palestinians have met in private, unofficial, academically based, problem–solving workshops designed to enable the parties to explore each other’s perspective, generate joint ideas for mutually satisfactory solutions to their conflict, and transfer insights and ideas derived from their interaction into the policy process. Most of the work takes place in small groups, but the focus is on promoting change in the larger system. This article discusses 5 ways in which the workshop group serves as a vehicle for change at the macrolevel. It does so by functioning as a microcosm of the larger system, as a laboratory for producing inputs into the larger system, as a setting for direct interaction, as a coalition across conflict lines, and as a nucleus for a new relationship.
