# Psychological Continuity **Domain:** Philosophy of Mind / Neuroethics / Identity **Doc Type:** Concept Node **Maturity:** Established Philosophical Concept, Emerging Governance Concern **Related:** [[Personal Continuity Ontology]], [[Autobiographical Memory]], [[Cognitive Liberty]], [[Memory Continuity]] --- ## Definition **Psychological continuity** is continuity across time through overlapping relations of memory, intention, personality, values, commitments, agency, and self-recognition. It need not imply that every property remains unchanged. ## Neurotechnology relevance Systems that alter memory, affect, decision-making, or self-models can affect continuity without physically destroying a person. Governance therefore must address manipulation and identity change as well as data extraction. ## Digital Afterlife Interface **Evidence / Concept Status:** Recognized in intergovernmental and national policy discourse; legal force varies. Psychological continuity is the closest existing rights vocabulary to continuity of self, but current policy use is principally a negative protection for living persons rather than a positive postmortem right to technological continuation. That boundary must remain visible when routing into [[wiki/Personal Identity Right|Personal Identity Right]], [[wiki/Neurorights|Neurorights]], [[wiki/Negative-to-Positive Continuity Gap|Negative-to-Positive Continuity Gap]], and [[wiki/Continuity Constitutionalism|Continuity Constitutionalism]]. ## Branching and Fission Psychological continuity may branch. If two successors inherit equally strong memory, intention and character relations from one predecessor, both can be psychologically continuous while they cannot both be the one numerically identical person under an ordinary one-to-one account. [[wiki/Derek Parfit|Derek Parfit]] uses cases of this kind to separate survival-relevant continuity from strict identity; [[wiki/Fission and Fusion of Persons|Fission and Fusion of Persons]] develops the governance problem. Branching therefore requires explicit rules for provenance, standing, inherited duties and non-impersonation. Choosing one branch as the “real” person is a legal or institutional act unless the selection criterion is independently justified.
