We revisit research on group-decision making, examining how humans make decisions not only in collaboration with other humans, but machines as well. This is done in a nuanced social decision task—lie detection. Compared to humans alone (68.8%), and computers alone (66.2%), humans and computers deciding together are more accurate, but only when computers “make the final decision” (75.7%).
