• Funding The authors have not declared a specific grant for this research from any funding agency in the public, commercial or not-for-profit sectors.

• Competing interests None declared.

• Provenance and peer review Not commissioned; internally peer reviewed.

• ↵As Jardas et al.1 note, the PPP has kin. But the differences among the various prediction algorithms aren’t relevant for what follows. So, following their lead, I focus just on the PPP.

• ↵Admittedly, Jardas et al gesture at some such restrictions and safeguards, but it’s not the primary focus of their project.

• ↵For a more in-depth discussion of this distinction as it applies to incapacitated patients, see Schwan2. For a helpful application to patient decision-making more generally, see Brudney and Lantos3. For a recent philosophical discussion of the distinction, see Enoch4.

• ↵An agent’s sovereign domain is the space of decisions that are properly theirs to control and hence generate autonomy-as-sovereignty considerations. See Feinberg5 for an early and influential discussion.

• ↵For more on the sovereignty considerations at stake for borderline incapacitated patients, see Schwan2.

• ↵Note that this concern is distinct from—though often coincidental with—sovereignty considerations that arise when a patient decides against the use of the PPP.
