My stress-test does not reveal a fatal internal inconsistency; the methodology is appropriate for an initial qualitative study, and the authors are appropriately cautious in the discussion. However, the central claim as quoted ('cannot be predicted from perceived usefulness and ease of use alone') makes a stronger assertion than the data can support. A quantitative replication/validation is the natural and concrete test. Since the reader already conditioned the verdict on further validation, my concern does not change the verdict.

This claim rests on qualitative analysis of 26 users recruited from a single Dutch law faculty via snowball sampling and 12 experts from an author-organized workshop, with coding performed by the first author alone. The sample is disproportionately legally literate and EU-centric, which plausibly explains the prominence of systemic (public vs. market providers, monopoly avoidance) and external (GDPR/AI Act compliance, oversight) themes. A crucial, untested inference is that Systemic Conditions constitutes a distinct UTAUT construct needed to explain PPA acceptance; the paper itself concedes rigorous construct validation is required. Absent such validation, the assertion that acceptance 'cannot be predicted from perceived usefulness and ease of use alone' overstates the evidence. If these themes do not recur in a more diverse sample or fail to add predictive validity beyond existing UTAUT constructs, the three-theme structure may be an artifact of this particular, legally informed, EU-focused participant pool.","agreement_with_reader":"partial"},"referee_report":{"model":"deepseek-v4-flash","summary":"This paper reports a qualitative focus-group study (five groups; 26 potential users and 11–12 domain experts) on the acceptability of personalized privacy assistants (PPAs).

The paper is also honest in noting that the proposed UTAUT extension would require rigorous construct validation. Its main value is as a hypothesis-generating qualitative study rather than as a confirmatory test of an acceptance model.","major_comments":[{"comment":"The central claim about extending UTAUT is presented in stronger terms than the evidence supports. The paper states that Systemic Conditions 'could create a distinct construct for UTAUT' and then concedes that this 'demands rigorous construct validation before it can be integrated.' Yet the abstract and conclusion present the findings as 'theoretical extensions' and assert that acceptability 'cannot be reduced to AI technology or privacy alone.' Without discriminant-validity or predictive-validity evidence, the stronger formulations overstate what a qualitative study can establish. Recommend consistently framing the UTAUT extension as a set of hypotheses for future quantitative work, and softening the abstract/conclusion accordingly.","section":"Discussion / 'Extending technology acceptance models...'"},{"comment":"The sample is narrow: 26 users recruited from one Dutch law faculty via snowball sampling, and 12 experts from an author-organized workshop with a heavy legal/social-science concentration. The paper acknowledges EU-specificity, but it does not discuss how this legally literate, EU-focused participant pool may have privileged certain themes, particularly Systemic Conditions (public vs. market providers, monopoly avoidance). In addition, coding was performed by the first author alone, and the Results section contains no participant quotes or other raw-data excerpts to support the themes. This combination makes the three-theme structure a credible but weakly evidenced reconstruction. The manuscript should either provide a thicker audit trail (e.g., representative quotes, coding examples) or explicitly limit the generality claims, which would strengthen the contribution.","section":"Methodology (participant recruitment and analysis)"},{"comment":"The paper states that the FG4-5 guide was structured around UTAUT2 constructs but that these were 'not used as a theoretical framework for analysis.' This distinction between data collection and analysis is helpful, but the wording of the questions (usefulness, ease of use, social influence, facilitating conditions, price value) may have steered participants toward UTAUT-aligned responses. The later mapping of themes to UTAUT is therefore somewhat circular even if the coding was open. The authors should address this possibility directly, for instance by specifying what steps were taken to remain open to non-UTAUT topics and by acknowledging this as a limitation in the interpretation of the UTAUT extension.","section":"Methodology, FG4-5 question guide"}],"minor_comments":[{"comment":"The abstract reports expert n = 11, while Table 1 reports 12 participants (8 Law, 2 Social Science, 1 Philosophy, 1 Industry).

It does not prove that UTAUT needs a new construct, and the authors mostly do not claim it does.\n\nWhat is actually new: prior work (Stover et al.; Colnago et al.) looked at user perceptions of PPAs but did not systematically compare users to experts, and the systemic conditions theme — provider type, public vs market provision, monopoly avoidance — is a genuinely new addition to the acceptance discussion. The paper ships a transparent method: five focus groups, reflexive thematic analysis, open coding, and an explicit statement that the UTAUT-derived questions in FG4–5 were not used as an analysis framework. That last point matters, because it lowers the circularity risk; the systemic theme appears prominently in the non-UTAUT guides too.\n\nSoft spots: the sample is the whole story. Twenty-six users recruited by snowball from one Dutch law faculty, plus twelve experts from an author-organized workshop, mostly legal and social science. It is entirely plausible that the prominence of systemic/external themes (GDPR compliance, public providers, monopoly) reflects that legally literate, EU-centric pool. The stress-test is right to call the three-theme structure sample-dependent until it recurs elsewhere. But the paper already concedes most of this in its limitations and explicitly calls for construct validation before the UTAUT extension is taken seriously, so the conclusion “cannot be reduced to AI technology or privacy alone” is calibrated; the reader’s paraphrase “cannot be predicted from perceived usefulness and ease of use alone” is a bit stronger than the paper actually says.\n\nMinor: single-researcher coding is real but not fatal under reflexive TA, which does not claim inter-coder reliability; an audit trail would help. And the abstract says experts n=11 while Table 1 says 12 — sloppy and easy to fix.\n\nBottom line: worth a serious referee. It is a careful, honest exploratory contribution for the HCI/privacy and technology-acceptance crowd. I would send it out, ask for the n fix and a small softening of the abstract/conclusion if needed, and let it land as a hypothesis-generating study.","headline":"A transparent, exploratory focus-group study whose three-theme account of PPA acceptability (Design, External, Systemic) is plausible and useful, but the legally literate EU sample makes those themes hypotheses to validate, not settled findings.","tokens_in":16837,"tokens_out":4634,"would_cite":true,"duration_ms":47961,"reading_group":"yes","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"Acceptance of personalized privacy assistants hinges on three condition clusters, not just perceived usefulness.","keywords":["personalized privacy assistants","technology acceptance","UTAUT","focus groups","reflexive thematic analysis","privacy","AI assistants","systemic conditions"],"falsifier":"A large representative survey across EU and non-EU countries that measures the three themes alongside standard UTAUT variables (performance expectancy, effort expectancy, social influence) and tests whether systemic conditions (provider type, monopoly concerns, cost model) add incremental predictive power for behavioral intention to use a PPA.
