This course examines the science and practice of decision-making through the lens of psychology, behavioral economics, and management. Students explore the cognitive biases, heuristics, and emotional influences that shape decisions and learn how to create value by designing effective decision-making strategies. Anchored in Ellen Langer's principle the psychology of possibility and enriched by key frameworks like prospect theory, the broaden-and-build theory, and growth mindset, the course connects theory with practice. Students tackle real-world scenarios, participate in negotiation simulations, and analyze decision-making through cultural and organizational perspectives. By the end of the course, students have developed the critical thinking skills and practical tools to address complex problems, lead with confidence, and enhance decision-making processes in their organizations and industries.
