The reader's weakest_assumption, however, focused on the empirical assumption about human use of yellow flags and override behaviour. While that is a genuine fragility, I identify a more load-bearing concern: the central claim is a legal conclusion, and the section that would contain the doctrinal argument (Section 4) is not present in the supplied text. Without it, the claim is not merely empirically uncertain; it is unverifiable in the material provided. The paper explicitly says Section 4 will assess both interventions under relevant UK laws, and the introduction frames the proportionality argument as a principal contribution. The supplied text jumps from Section 3.2.1 to references, so there is no way to check whether the legal reasoning is sound or even present. This is a concrete, locatable gap: Section 4 is referenced but omitted. My concrete test is to retrieve the actual paper and check whether Section 4 exists and supports the claim. I therefore partially agree with the reader: the empirical assumption is fragile, but the missing legal analysis is the most immediate blocker to the central claim.

Every other argument in the paper (uncertainty distributions, human override behaviour, two-track decision processes) is in service of a legal conclusion that is never demonstrated.

The paper defines two uncertainty-based algorithmic interventions for AI-assisted decision-making—selective abstention (withholding high-uncertainty predictions) and selective friction (showing predictions with a yellow-flag warning)—and applies them to two case studies: consumer credit and risk of reoffending. Its stated central contribution is a doctrinal analysis under UK law, arguing that selective friction is legally preferable to selective abstention because it preserves access to the prediction and is more likely to satisfy proportionality under the Equality Act 2010. The argument is conditional, with the paper explicitly acknowledging that whether friction improves decision quality in practice is uncertain.

The paper has notable strengths: it formalizes the two interventions clearly, states its assumptions explicitly (calibration, entropy thresholds, trained users), grounds its case studies in concrete decision scenarios, and is unusually honest about empirical uncertainty, including the possibility that friction may not improve decision quality. The use of case law and empirical evidence on lender overrides is promising. Nevertheless, as submitted, the paper's central claim—that friction is legally preferable under the Equality Act 2010—is entirely unverifiable because the legal analysis that would establish it is absent. The mismatch between the arXiv metadata and the full text compounds this, making the submission incoherent as a reviewable paper.","major_comments":[{"comment":"The paper's central claim—that selective friction is legally preferable to selective abstention under the Equality Act 2010—is asserted in the introduction and abstract but never demonstrated.

The legal argument for preferability depends on the missing Section 4 to weigh these risks against the purported benefits of friction.

The arXiv metadata describes a weakly supervised affordance grounding paper; the full text is a UK law and policy analysis of selective abstention versus selective friction. Treating the full text as the manuscript, it's a thoughtful policy paper that is missing its central section, so the main legal conclusion is unverifiable from what's in front of us.\n\nWhat the full text does well: the friction-versus-abstention comparison framed through the Equality Act 2010 appears genuinely new relative to the ML fairness literature on abstention disparities. The paper is refreshingly candid about what it doesn't know, explicitly saying that whether friction improves decision quality is uncertain. The formal setup—entropy threshold, two-track decision process, the four scenarios in Table 1—is clean and makes the argument easy to follow. The sections on credit and reoffending are careful about the limits of the COMPAS analogy.\n\nSoft spots: the load-bearing problem is that Section 4, the legal analysis, is missing. The introduction says Section 4 assesses both interventions under UK law and Section 5 concludes. The text I have jumps from 3.2.1 straight to references. So the central claim that friction is 'legally preferable' because it is 'more likely to satisfy proportionality' rests entirely on an argument we cannot see. The metadata mismatch is a separate hard problem: no editor or reviewer can certify a paper when the title, authors, and abstract describe a different work. The assumptions about trained users and non-adversarial friction are stated clearly, but they remain empirical premises; the override evidence cited goes some way, yet the paper itself concedes the decision-quality effects are uncertain.\n\nWho it's for: people interested in human-AI decision-making and UK/EU non-discrimination law. If the complete version contains the missing legal analysis, it deserves a serious referee. As supplied, it does not.\n\nRecommendation: desk reject or require the authors to submit the complete, correctly identified manuscript.

The argument is developed through two case studies—consumer credit and risk of reoffending—and through a four-scenario analysis of what happens when a human concurs with or overrides an uncertain prediction.
