Postmortem avatars in grief therapy: Prospects, ethics, and governance
Pith reviewed 2026-05-10 15:35 UTC · model grok-4.3
The pith
Postmortem avatars can be used ethically in grief therapy because no major objection rules them out in clinical settings.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Postmortem avatars, which are AI models fine-tuned on a deceased person's data, can be integrated into grief therapy through imaginal exercises such as the empty chair technique and through the creative process of building the avatar itself. Drawing on the dual-process model of grief and the theory of continuing bonds, the authors treat these avatars as fictional aids rather than literal recreations. They examine five ethical objections and maintain that none of them provide decisive reasons against therapeutic deployment, largely because the structured clinical environment supplies safeguards around consent, authenticity, and psychological safety that are absent in casual uses.
What carries the argument
The framework that treats postmortem avatars as fictional continuing bonds within established grief therapy techniques, allowing ethical objections to be assessed against the protective effects of clinical oversight.
If this is right
- Therapists could add postmortem avatars to existing imaginal exercises to help clients sustain meaningful bonds with the deceased.
- The act of creating a postmortem avatar could itself become a structured art-therapy activity that aids grief processing.
- Clinical contexts reduce the force of ethical objections that apply more strongly to non-professional or commercial uses of the same technology.
- Governance systems must still develop clear standards for data use, posthumous consent, and professional accountability.
- Empirical trials are needed to measure actual therapeutic outcomes and to identify any hidden psychological costs.
Where Pith is reading between the lines
- If the approach proves workable, families and individuals might begin curating digital archives specifically for future therapeutic use after death.
- Legal questions about ownership and control of a person's digital likeness after death would become more pressing.
- The same technology could be tested in related areas such as supporting people with dementia or processing other forms of loss.
- Commercial services offering postmortem avatars outside therapy would likely require separate and stricter rules to prevent exploitation.
Load-bearing premise
The assumption that clinical therapeutic frameworks and professional oversight will reliably limit harms from inauthenticity, missing consent by the deceased, and unintended emotional effects.
What would settle it
A controlled study finding that patients assigned to use postmortem avatars show higher rates of complicated grief, prolonged distress, or dependency than patients receiving standard therapy alone would undermine the safety argument.
read the original abstract
Postmortem avatars (PMAs) -- AI systems that simulate a deceased person by being fine-tuned on data they generated or that was generated about them -- have attracted growing scholarly attention, yet their potential role in clinical settings remains largely unexplored. This paper examines the ethics of deploying PMAs as therapeutic tools in grief therapy. Drawing on the dual-process model of grief, the theory of continuing bonds, and the philosophical framework of fictionalism, we propose two potential therapeutic applications: incorporating PMAs into established imaginal exercises such as the empty chair exercise, and treating the process of PMA creation as an art-therapeutic exercise in its own right. We consider five ethical objections to these applications and argue that none constitute knock-down arguments against therapeutic use, particularly given the risk-mitigating role of the clinical context. We conclude by identifying outstanding governance challenges and calling for empirical research, without which neither the promise nor the dangers of therapeutic PMAs can be adequately assessed.

Referee Report
Summary. The paper claims that postmortem avatars (PMAs)—AI systems fine-tuned on data from or about a deceased person—can be ethically used in grief therapy via two applications: integrating PMAs into imaginal exercises such as the empty-chair technique, and framing PMA creation itself as an art-therapy process. Drawing on the dual-process model of grief, continuing-bonds theory, and philosophical fictionalism, the manuscript reviews five ethical objections (authenticity, consent, harm, etc.) and argues that none constitute knock-down arguments against therapeutic deployment, primarily because the clinical context supplies risk-mitigating safeguards. It concludes by outlining governance challenges and calling for empirical research to evaluate both benefits and dangers.
Significance. If the central claim is substantiated, the work is significant as one of the first structured ethical analyses of an emerging AI technology in clinical grief therapy. It earns credit for grounding its proposals in established psychological frameworks (dual-process grief model, continuing bonds, fictionalism) rather than ad-hoc invention and for identifying concrete applications and governance gaps instead of issuing blanket endorsements or prohibitions. The balanced treatment of objections and the explicit call for empirical validation provide a useful starting point for interdisciplinary work at the intersection of AI ethics and mental-health practice.
major comments (2)
- [section on ethical objections and clinical mitigation] The section discussing the five ethical objections and their rebuttals: the central claim that 'none constitute knock-down arguments... particularly given the risk-mitigating role of the clinical context' is asserted without operational detail. No concrete mapping is provided showing how standard therapeutic safeguards (informed-consent checklists, session protocols, outcome monitoring) would be adapted to AI-specific issues such as the authenticity of generated speech, data provenance from the deceased, or potential attachment to a non-human entity. This leaves the mitigation argument as an assumption rather than a demonstrated buffer, directly affecting whether the objections are shown to be non-decisive.
- [section proposing therapeutic applications] The subsection proposing the two therapeutic applications (PMA-augmented empty-chair exercises and PMA creation as art therapy): while the applications are described at a high level, there is no discussion of how the dual-process or continuing-bonds frameworks would be modified to accommodate the non-human, data-derived nature of the avatar, leaving the therapeutic rationale incomplete for the very risks the paper later claims are mitigated by clinical context.
minor comments (3)
- [Abstract] Abstract: the five ethical objections are referenced but not enumerated; adding a parenthetical list would improve immediate clarity for readers scanning the abstract.
- [References] References: full citations for the dual-process grief model, continuing-bonds theory, and fictionalism should be supplied in the reference list to allow readers to trace the foundational sources.
- [Conclusion] Conclusion: the call for empirical research would be strengthened by suggesting at least one or two example study designs (e.g., controlled comparison of PMA-augmented vs. standard empty-chair sessions) to guide future investigators.
Simulated Author's Rebuttal
We thank the referee for their detailed and constructive report. The comments correctly identify places where the manuscript's arguments would benefit from greater operational specificity. We address each major comment below, indicating revisions that will be incorporated in the next version.

Referee: The section discussing the five ethical objections and their rebuttals: the central claim that 'none constitute knock-down arguments... particularly given the risk-mitigating role of the clinical context' is asserted without operational detail. No concrete mapping is provided showing how standard therapeutic safeguards (informed-consent checklists, session protocols, outcome monitoring) would be adapted to AI-specific issues such as the authenticity of generated speech, data provenance from the deceased, or potential attachment to a non-human entity.
Authors: We accept this assessment. The original manuscript relies on the general claim that clinical oversight supplies safeguards without illustrating how those safeguards would be operationalized for PMA-specific risks. In revision we will add a new paragraph (or short subsection) that supplies illustrative mappings: for example, an informed-consent checklist item requiring disclosure of training-data provenance and model limitations; a session protocol requiring the therapist to log instances of generated speech that deviate from known biographical facts; and outcome-monitoring items that track attachment intensity via validated scales adapted for digital entities. These additions will make the mitigation argument demonstrative rather than assumptive while remaining within the paper's conceptual scope. revision: yes

Referee: The subsection proposing the two therapeutic applications (PMA-augmented empty-chair exercises and PMA creation as art therapy): while the applications are described at a high level, there is no discussion of how the dual-process or continuing-bonds frameworks would be modified to accommodate the non-human, data-derived nature of the avatar, leaving the therapeutic rationale incomplete for the very risks the paper later claims are mitigated by clinical context.
Authors: We agree that the therapeutic rationale is underdeveloped on this point. The manuscript invokes the dual-process model and continuing-bonds theory but does not explicitly address how their constructs must be adjusted when the 'bond' is with a synthetic, data-derived representation. In the revised version we will insert a brief discussion immediately after the description of the two applications. It will note that continuing-bonds theory already accommodates non-corporeal objects (e.g., photographs, letters) and can be extended to digital avatars provided the patient retains awareness of their fictional status, consistent with the fictionalism framework already cited. For the dual-process model we will indicate that the 'restoration' orientation may require additional therapeutic work to distinguish adaptive engagement with the avatar from maladaptive avoidance of grief reality. These clarifications will tighten the link between the proposed applications and the risk-mitigation claim. revision: yes
Circularity Check
No significant circularity; analysis grounded in external frameworks
full rationale
The paper draws on established external psychological and philosophical sources—the dual-process model of grief, continuing bonds theory, and fictionalism—to outline two therapeutic applications and evaluate five ethical objections. No mathematical derivations, fitted parameters, self-definitional loops, or load-bearing self-citations appear in the provided text or abstract. The central claim that clinical context mitigates risks is advanced as an interpretive argument supported by these independent references rather than reducing by construction to the paper's own inputs or prior results. The analysis is therefore self-contained against external benchmarks.
