Computer Weekly referenced research by Columbia Business School’s Tianyi Peng and Olivier Toubia in a discussion about artificial intelligence systems that model and simulate human behavior. Their study, Twin-2K-500: A Data Set for Building Digital Twins of over 2,000 People Based on Their Answers to over 500 Questions, examines how large-scale behavioral data can be used to construct digital representations of individuals. The research highlights both the promise and ethical considerations of AI systems designed to predict, mirror, and respond to human decision-making.
