Abstract: Humans and AIs are often paired on decision tasks with the expectation of achieving
complementary performance -- where the combination of human and AI outper-
forms either one alone. However, how to improve performance of a human-AI
team is often not clear without knowing more about what particular information
and strategies each agent employs. In this paper, we propose a model based in
statistically decision theory to analyze human-AI collaboration from the perspec-
tive of what information could be used to improve a human or AI decision. We
demonstrate our model on a deepfake detection task to investigate seven video-level
features by their unexploited value of information. We compare the human alone,
AI alone and human-AI team and offer insights on how the AI assistance impacts
people’s usage of the information and what information that the AI exploits well
might be useful for improving human decisions.
