In his book Agent_Zero: Toward Neurocognitive Foundations for Generative Social Science, SFI External Professor Joshua Epstein introduces a new theoretical software entity: Agent_Zero. 

Grounded in contemporary neuroscience, this software individual, or "agent," is endowed with distinct emotional/affective, cognitive/deliberative, and social modules. When multiple agents of this new type move and interact spatially, they collectively generate a range of dynamics spanning the fields of social conflict, psychology, public health, law, network science, and economics.
