In an age of profound division, identifying common ground for societal consensus has become increasingly challenging. This urgency has underscored the need to uncover the fundamental principles enabling group decision-making. Recent literature suggests a new social contract theory may be required to redefine the reciprocal obligations between individuals and society. Group Decision and Negotiation (GDN) research has long addressed this core issue, now flourishing in new areas such as procedural choice and meta-decision problems. These emerging fields theorize how individuals autonomously form the rules and institutions that facilitate collective action. This keynote will reflect on the speaker’s journey toward establishing such theoretical and pragmatic foundations for a robust group decision science.<\/p><\/div><\/div><\/div><\/div><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Masahide Horita is currently a Professor at the Department of Civil Engineering, University of Tokyo. His areas of interest include: procedural choice, theory of meta-decisions, evolution of cooperation, infrastructure systems management, and AI\/DX in construction. He received a PhD from the London School of Economics in 1999 and subsequently worked at Durham Business School as Senior Research Associate until he moved to the University of Tokyo in October, 2000. He is the author of a number of papers and books, including Innovations in Collaborative Urban Regeneration,<\/em> (co-edited with Koizumi, H) Springer. Professor Horita also advises home and overseas governments on various infrastructure policies, serving on the Central Construction Industry Council. He is a member of IEEE, a Fellow of the Japan Society of Civil Engineers (JSCE), and an associate editor of Group Decision and Negotiation journal. His recent paper, \u201cSocial Ranking Problem Based on Rankings of Restricted Coalitions,\u201d co-authored with Takahiro Suzuki, was awarded as the Best Paper in GDN 2021.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Were one to ask an AI system to answer the question \u201cWould a machine such as you be able to negotiate a conflict impartially?\u201d, the answer reveals major issues with AI systems today such as potential bias in training data, understanding impartiality, lack of emotional intelligence, and the need for transparency and explainability.\u00a0 We propose a way to address these issues with research involving the Analytic Hierarchy Process and its extensions to the continuous case, and how our approach can be used in conflict resolution.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
