Do people organically sever ties to misinformation spreaders? And what predicts doing so? We tracked ∼900K followers of ∼5K health misinfo spreaders on Twitter. Misinformation ties are persistent: 99.5% of misinfo ties persist each month.

Interpretability tools are intended to help people better understand ML; we find that they can impair understanding. This paper presents an experiment showing that ML practitioners spent 5x less time on task, and were 17% less accurate, with access to interpretability tools.

We propose an alternate framework for ML interpretability grounded in Weick’s sensemaking theory, which focuses on who the explanation is intended for. The paper introduces design guidelines for sensible AI, AI that factors in human cognition when explaining itself.
