The keynote address "Social Impact of University Rankings" will critically explore how university rankings affect institutions and society. While universities often prioritize rankings for reputation and funding, this talk will examine their impact on educational policy, institutional behavior, and societal perceptions. It will analyze both the positive and negative effects, using case studies to illustrate how rankings influence university strategies, student demographics, and faculty dynamics. The goal is to provoke a thoughtful examination of whether pursuing higher rankings aligns with the educational and social missions of higher education institutions.
