On April 12, 2018, at the Kellogg School of Management at Northwestern University, we hosted a conference on the frontiers of culture and negotiation research. The conference brought together scholars from two vibrant areas of research-cultural psychology and negotiation-in order to stimulate future research at the intersection of culture and negotiation.For years, these two areas remained isolated from each other: Negotiation research, which developed in the West, tended to ignore culture. Culture research, while global in its scope, tended to ignore negotiation. Back in 2003, we hosted a conference, again at Northwestern, to begin to integrate theory, research, and practice in both fields. We asked pairs of scholars from both culture and negotiation research to write on a topic relevant to both, including basic psychological processes (e.g., cognition, motivation and emotion), the social process (e.g., communication, conflict, and disputing) and the social context (e.g., intergroup relationships, third parties, justice, technology, and social dilemmas) which culminated in the Handbook of Negotiation and Culture (Stanford University Press). Our goals in that volume were to compile an up-to-date review of current knowledge of negotiation, to challenge negotiation theorists to more inclusive of all humankind, and to encourage cultural theorists to provide an explanation for patterns of thought and action in an important area of social interaction. The authors identified numerous knowledge lacuna-opportunities for research for decades to come-and also identified the limits of the Western culture-based findings (Figure 1).
