Asymmetric uncertainty regulation in human–artificial intelligence interaction

Frontiers in Artificial Intelligence
IntroductionHuman–AI interaction is commonly framed as a problem of uniformly minimizing uncertainty across the joint system. We challenge this assumption by proposing Asymmetric Uncertainty Regulation (AUR), a dynamical framework in which stable and ...
