The Complexity of Causality and Responsibility for Query Answers and non-Answers
Summary: Adapts Halpern-Pearl-Chockler causality to define causes and responsibility for answers and non-answers, with ranking. Conjunctive-query causes are PTIME; responsibility has a PTIME/NP-complete dichotomy with max-flow in PTIME and LOGSPACE-hardness. (summarized by gpt-5-nano on Feb 09 2026)
