Blameworthiness in Multi-Agent Settings

Understand

We provide a formal definition of blameworthiness in settings where multiple agents can collaborate to avoid a negative outcome.

• We first provide a method for ascribing blameworthiness to groups relative to an epistemic state (a distribution over causal models that describe how the outcome might arise).
• We then show how we can go from an ascription of blameworthiness for groups to an ascription of blameworthiness for individuals using a standard notion from cooperative game theory, the Shapley value.
• We believe that getting a good notion of blameworthiness in a group setting will be critical for designing autonomous agents that behave in a moral manner.
