Acts of Configuration: Rethinking Provenance, Temporality and Legitimacy in Post-Mortem Agents
For researchers and designers of AI agents for end-of-life scenarios, this work provides empirical insights into user preferences for agentic delegation post-capacity loss, highlighting tensions between provenance, temporality, and legitimacy.
The paper challenges the life/death binary in designing post-mortem agents by studying how people reason about AI agents for Advance Care Planning when users lose decisional capacity. Findings reveal that participants prefer bounded agents with first-party authorship and static behavior after capacity loss, but allow evolution before loss, introducing the concept of 'adjacent use' driven by persona persistence.
Work on persona-persistent post-mortem agents typically frames design around a life/death binary. This framing neglects a consequential yet under-theorised condition: when individuals remain alive but have impaired decisional capacity. Drawing on a multi-phase workshop in which participants trained and reflected on an AI agent for Advance Care Planning, we examined how people reason about agentic delegation post-capacity loss. Initially, participants favoured bounded agents grounded in first-party authorship and representational fidelity over autonomous or evolving stand-ins. However, temporality introduced novel ideas like adjacent use driven by persona persistence over functional expansion: agents should evolve while users retain capacity, remain static once capacity is lost, but somehow inform adjacent post-mortem uses. We discuss the implications of these findings and propose that the configuration of agents for post-capacity use reshapes our understanding of provenance, temporality, and legitimacy for post-mortem agents.
