Responsibility Handoff Without Accepted Uptake: Why Sending a Task Does Not Make It Someone Else's

This conceptual paper introduces Responsibility Handoff Without Accepted Uptake, a mechanism in which a sender treats delivery of a message or task as a transfer of responsibility while the recipient treats the same event as receipt of information, leaving no one to undertake the next action. The account assesses responsibility after a handoff by distinguishing delivery, acknowledgment, acceptance, and the rule of responsibility established by the applicable practice. Proof that information arrived does not by itself establish that responsibility moved. Under some procedures, however, receipt itself constitutes acceptance, so the governing handoff rule must be identified before a failure of uptake can be inferred. The discussion connects the mechanism to Patterson and colleagues’ study of handoff strategies in high-consequence settings and examines a reported orthopedic referral failure described by Karsh. A cancellation notice reached two clinicians, but the expected follow-up did not occur. The source infers that the recipients believed the primary care physician was handling the next step. The case documents delivery without the expected action; the recipients’ interpretation remains an inference from the source. Part of the Coordination and Dependence series within On Human Modeling, the paper examines how responsibility can fall between participants even when information is successfully transmitted. Its framework can inform human–AI research on workflow automation, task delegation, multi-agent systems, and interfaces that need to represent not only whether a message was delivered but whether responsibility for the next action was actually accepted.
