Agents don't always accept new information wholesale—this framework lets them selectively accept parts of compound information based on source-dependent credibility constraints, providing a more realistic model of belief change.
This paper extends belief update theory to handle cases where agents can only partially accept new information from different sources. It introduces selective credibility-limited belief update, where incoming information is weakened based on what each source world can credibly support, then incorporated. The framework unifies and generalizes existing belief update approaches.
