Our dream is to use AI to create realistic large-scale simulations where each agent in the simulations behaves like a human. Current agent-based behavior models and simulations strip away critical facets of human behavior. This prevents us from achieving real insight into intractable social problems like sexism, racism and radicalization to name a few. We will build both an agent model and a simulation system that is capable of performing deep behavioral simulations on a scale that has not been attempted so far.
