  In August of 2021, the Santa Fe Institute hosted a workshop on collective
intelligence as part of its Foundations of Intelligence project. This project
seeks to advance the field of artificial intelligence by promoting
interdisciplinary research on the nature of intelligence. The workshop brought
together computer scientists, biologists, philosophers, social scientists, and
others to share their insights about how intelligence can emerge from
interactions among multiple agents--whether those agents be machines, animals,
or human beings. In this report, we summarize each of the talks and the
subsequent discussions. We also draw out a number of key themes and identify
important frontiers for future research.
