At Columbia University's Sustaining Peace Conference Lukasz Jochemczyk of the University of Warsaw presented the Dynamical Negotiation Network model, a new way to explore how to think about and construct negotiation talk, particularly for difficult conflicts. The purpose of negotiation is to achieve a joint decision. When people negotiate, they create a shared representation of the problem. This representation serves as a foundation for developing a joint decision through the negotiation process. In this workshop, Lukasz will show how the quality of the shared representation of the problem relates to the outcome of negotiation. The workshop will also explore ways to achieve a better outcome.
