Separation of Grounded Exclusion From Deprioritization and Omission: Why the Way an Option Leaves an Inquiry Matters
Year: 2026
Type: article
Abstract: This conceptual paper introduces Separation of Grounded Exclusion From Deprioritization and Omission, an evaluative criterion for assessing how options leave an inquiry. Identical shortlists can result from grounded exclusion, exclusion on grounds that fail or cannot be checked, lower priority, or omission without a stated reason. Grounded exclusion requires a stated constraint that is relevant, justified, applicable to the case, and violated by the option. Recoverability depends separately on timing, records, authority, and resources. A later justified exclusion does not by itself establish that an earlier removal had grounds. The discussion relates the criterion to Bachrach and Baratz’s account of nondecisions and examines the Columbia Accident Investigation Board’s account of requests for wing imagery. The case involves stated reasons for removal, so it does not document unexplained omission. The Board’s rescue analysis depended on early recognition and favorable operational conditions; it did not establish that imagery would have saved the crew. Part of the Possibility and Counterfactual Structure series within On Human Modeling, the paper offers questions about how options leave consideration and who can restore them. Its framework can inform human–AI research on whether systems preserve inspectable reasons for excluding or deprioritizing alternatives and distinguish those decisions from unexplained omission.
