The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The interpersonal–institutional dispute dimension recovered by exploratory then confirmatory factor analysis on the same 46 vignettes; it is the latent organization that both predicts baseline AI preference and channels the effects of the emotion and prototypicality manipulations.
What would settle it
Direct classification tasks, reaction-time or process-tracing measures, or priming that forces institutional versus relational construal before any acceptability rating is collected: if induced classification does not shift subsequent AI preference in the predicted direction, the classification-mechanism claim fails.
Extended reading notes
Core claim
Acceptability judgments for AI versus human adjudication form a stable two-dimensional structure—interpersonal-relational versus institutional-procedural—and that structure is causally sensitive to experimentally manipulated emotional involvement and prototypicality, with AI-specific expectations as the dominant proximal predictor.
Load-bearing premise
That the two-factor pattern recovered from the very ratings used as the dependent variable, plus the framing effects, can be read as evidence that people first classify the dispute and then decide on the adjudicator, rather than both patterns arising from shared emotional or moral reactions that were never measured separately.
Editorial extensions
If this is right
- AI legal tools should be piloted first in high-consensus institutional domains (traffic, regulatory, contractual) where public acceptance is higher and less variable.
- Interpersonal cases (custody, violence, child welfare) require robust human oversight and transparent limits if legitimacy is to be preserved.
- Communication that targets specific AI capabilities and risks will move acceptance more than generic technology campaigns or personality-based outreach.
- Gender-differentiated responses under emotional framing imply audience-segmented messaging may be needed, at least within the studied cultural setting.
- Technology-acceptance models that ignore dispute content will systematically mis-predict uptake across judicial domains.
Reading between the lines
- If the interpersonal–institutional split is culture-general, the same two-factor map could serve as a design template for hybrid human–AI systems outside Japan.
- The large effect of AI-specific expectations suggests that short, case-type-matched educational interventions could produce measurable acceptance shifts faster than long-term personality or demographic change.
- Boundary cases that load on both factors (armed robbery, workplace overwork) are natural test beds for measuring competing classification schemes in real time.
- Once process measures confirm or refute the classification step, the same vignette battery could be re-used to isolate emotional, moral-foundation, or fairness pathways that currently remain confounded.

Referee Report
Summary. The paper argues that public acceptance of AI versus human legal adjudication is shaped not only by individual differences but by psychological features of dispute content. Across two Japanese online-panel studies (N=1,384; N=596), Study 1 uses exploratory factor analysis on acceptability ratings of 46 single-sentence vignettes and recovers a two-factor structure distinguishing interpersonal-relational disputes (stronger human preference) from institutional-procedural disputes (comparatively higher AI acceptance). Study 2 replicates the structure with a five-point scale, experimentally manipulates emotional involvement and prototypicality, and finds a three-way interaction with gender plus a large main effect of AI-specific expectations (η2=0.252). The authors interpret the pattern through categorization and construal-level theory while acknowledging that classification itself was not measured and that emotion, moral intuition, or fairness may produce similar covariation.
Significance. If the descriptive claim holds, the work usefully extends technology-acceptance models by showing that dispute type is a systematic source of variance in AI legitimacy judgments, with clear practical implications for phased judicial AI deployment. Strengths include a large exploratory sample, independent-sample replication across response formats, sensitivity analyses on exclusion thresholds, and transparent discussion of alternative mechanisms and generalizability limits. The contribution is primarily empirical and descriptive rather than a definitive demonstration of cognitive classification as a causal mechanism; that framing is appropriately hedged in the General Discussion.
major comments (3)
- §5.1.2 and §5.2.1 correctly note that the two-factor structure is recovered from the same acceptability ratings that serve as the DV (Study 1 EFA, Table 2; Study 2 replication, Table 5). The central claim is therefore best stated as systematic preference covariation by dispute type plus experimental modulation, not as evidence that cognitive classification is the mediating process. The Abstract and §1–2 still lean toward the stronger mechanism language; those sections should be aligned with the more cautious General Discussion so that the load-bearing claim matches what the design can support.
- Study 2 exclusion rate of 67.2% (§4.2.2) is high even for online experiments with dual attention and comprehension checks. Demographic comparisons (§4.4.2) show modest shifts (age, gender, occupation). The sensitivity analyses (§4.3.6) are helpful, but the manuscript should report whether the three-way interaction and the η2=0.252 AI-expectations effect remain significant and of similar magnitude under the attention-check-only and no-exclusion samples, not only that factor structure is recovered. Without that, the experimental claim rests on a selected subsample whose digital literacy and AI familiarity may differ from the target population.
- The single-sentence vignettes (§3.2.2, §5.2.3, §5.4) are an explicit design choice that may amplify prototype-based distinctions. The paper acknowledges ecological-validity limits but does not test whether the institutional–interpersonal split survives richer materials. At minimum, a short robustness check or a clearer boundary statement in the Abstract/Conclusion is needed so readers do not over-generalize from highly abstracted stimuli to real case materials.
minor comments (5)
- Table 1 and Table 4 omit Q10 and Q34 (attention checks) without a note in the table notes; add a brief explanation for completeness.
- TIPI-J fit is poor (CFI=0.789, RMSEA=0.186; §4.3.2). The text already notes ultra-brief-scale limitations; a sentence on why personality results should be treated as exploratory would help.
- Figure 2 caption reports η2 values for simple interactions; ensure the y-axis metric (summed composite vs mean) is stated so readers can interpret the plotted means (e.g., 110–129 range).
- Preregistration is absent for both studies; the authors note this. A brief OSF or similar deposit of analysis code and vignette list would strengthen reproducibility claims already partially supported by the AI-use OSF link.
- Minor wording: §1.2 “Categorization theory (Rosch, 1975; Murphy, 2004) that individuals…” appears to miss a verb (“proposes” or similar).
Circularity Check
Mild descriptive circularity only: the two-factor structure is recovered from the same acceptability ratings that serve as the DV; the paper itself treats this as descriptive, and Study 2 supplies independent experimental modulation.

[Study 1 §3.3.2 (EFA) and §3.4.2 / General Discussion §5.1.2, §5.2.1–5.2.2]
"Exploratory factor analysis with promax rotation extracted two factors accounting for 61.6% of variance... This two-factor structure should be interpreted as a descriptive organization of acceptability judgments that systematically covaries with evaluations of AI suitability across dispute types... the dimensional structure represents a descriptive summary of response patterns, not direct evidence for classification as a psychological mechanism."
The latent dimensions are defined by the loadings of the same acceptability items that constitute the dependent variable. Recovering ‘interpersonal vs institutional’ structure from those ratings is therefore a re-description of the DV’s covariance rather than independent evidence that cognitive classification causes the ratings. The paper correctly labels this descriptive and does not treat the EFA as a causal derivation; Study 2’s experimental manipulations supply the non-circular content.
full rationale
This is an empirical two-study paper (EFA + experimental framing), not a first-principles derivation. The only near-circular step is that Study 1’s two-factor solution is obtained by factor-analyzing the very acceptability ratings later treated as evidence that ‘psychological features of dispute content’ organize those ratings. That is a descriptive summary of the covariance of the DV, not an independent measurement of a latent classification process. The authors repeatedly flag exactly this limitation (§3.4.2, §5.1.2, §5.2.1–5.2.2) and list alternative mechanisms (emotion, moral foundations, fairness). Study 2 then (a) recovers the same structure on an independent sample with a different response format and (b) shows that experimentally manipulated emotional involvement and prototypicality shift the ratings in theoretically predicted directions, with AI-specific attitudes as the strongest covariate (η² = 0.252). No parameters are fitted and then re-labeled as predictions, no uniqueness theorem is imported from the authors’ prior work, and no ansatz is smuggled via self-citation. The central empirical claim—systematic variation by dispute type plus contextual modulation—therefore stands on independent experimental content. Score 2 reflects only the acknowledged descriptive circularity of the EFA step; it is not load-bearing for the paper’s strongest results.

Public acceptance of artificial intelligence (AI) in legal decision-making has been primarily explained through individual differences in personality traits and general technology attitudes. However, contextual features of legal disputes themselves may systematically influence preferences for AI versus human adjudicators. Across two studies with Japanese participants (N = 1,384 and N = 596), we examined whether psychological characteristics of dispute content shape acceptability judgments for algorithmic adjudication. Study 1 employed exploratory factor analysis on acceptability ratings across 46 legal dispute vignettes, revealing a two-dimensional structure distinguishing interpersonal-relational disputes (where human adjudicators were strongly preferred) from institutional-procedural disputes (where AI acceptance was comparatively higher). Study 2 replicated this structure in an independent sample and demonstrated that experimentally manipulated contextual features - emotional involvement and prototypicality - systematically modulated acceptability judgments, with effects varying by dispositional trust, AI-specific attitudes, and gender. AI-specific expectations emerged as the strongest predictor (eta2 = 0.252), and a three-way interaction among emotional involvement, gender, and prototypicality indicated that contextual effects are moderated by individual characteristics. These findings suggest that the psychological features of dispute content constitute an overlooked dimension in AI acceptance research, extending beyond technology acceptance models to fundamental questions about how individuals construe social problems and allocate adjudicative authority.
