Accurate AI Simulation of 1,000 Real Individuals Using GPT-4: Reproducing Their Behavior

In experiments that simulated more than 1,000 real people using the artificial intelligence model behind ChatGPT, we were able to reproduce their unique thoughts and personalities with high accuracy, making it possible to imitate individuals in this way. Concerns have been raised about the ethics of doing so.

Park Joon Sung Researchers at Stanford University in California wanted to use generative AI tools to model individuals as a way to predict the impact of policy changes. Historically, this has been attempted using simpler rule-based statistical models, with limited success.
