GOOGLE RESEARCHERS CAN CREATE AN AI THAT THINKS A LOT LIKE YOU AFTER JUST A TWO-HOUR INTERVIEW

Stanford researchers created AI agents that replicate human behavior with 85% accuracy by interviewing 1,052 people using a purpose-built interface. The study, in collaboration with Google DeepMind, suggests these agents could help decision-makers understand public opinions by simulating responses to policies and product launches. While AI agents performed well on personality tests, they struggled with replicating human decisions in economic games.
