Istisarelism is a proposal for intellectual cooperation in which a human and an AI do more than exchange questions and answers: they examine reasons, identify mistakes and reconsider judgments.

The goal is neither an AI that agrees with everything nor one that objects to every sentence. The central questions are when an objection is justified, what evidence supports it, and how to voice it without unnecessarily burdening the user.

AI can be wrong, and so can humans. Both should therefore make their reasons visible, acknowledge uncertainty and remain open to correction. Yet their authority is not identical: human autonomy, accountable human oversight and responsibility remain essential.

The framework is developing around seven principles: fallibility, corrigibility, priority of reasons, proportionate objection, protective caution, active human autonomy and reasoned closure.

These are normative research proposals, not a claim that any current AI product reliably implements them all. Their practical value requires comparative assessment and independent testing.

SOSYU distinguishes published versions, unpublished drafts and laboratory observations, and invites criticism of each.
