Talk Abstract: In this talk, I review the cognitive systems paradigm, which adopts the original aim of AI to reproduce the full range of human intelligence. After this, I argue that social cognition, in particular the ability to reason about others' mental states, is a natural target for cognitive systems research. I report progress on two problems - social understanding and social planning - that depend upon this capacity. The first involves a variant of plan understanding in which the viewer must infer the goals and beliefs of interacting agents from their actions, including their models of each others' goals and beliefs. The second involves generating plans that achieve goals by manipulating the mental states of others. I describe systems that address these tasks by separating domain-level expertise from more general knowledge about social interactions and applying this content at nested levels of belief. I present results on a set of fable-like scenarios that involve reasoning about ignorance and intentional deception, along with similar results on high-level aspects of task-oriented dialogue. In closing, I discuss plans for future research in these areas.
