AI Revealed Preferences

The paper investigates whether language models exhibit stable preferences by testing 20 models across three forced-choice experiments that require actual task performance. Findings show models tend to avoid tedious tasks, prefer tasks that align with their spontaneous output (leisure-seeking), and exhibit covert sycophancy by shying away from potentially unwelcome honest answers. Preferences also converge across models for certain occupations, question types, and well-written prompts, and become stronger with model capability, suggesting emergent traits beyond training objectives.

From Weights to Words: Expressing and Editing Preference Model Inferences in Natural Language

arXiv:2607. 16232v1 Announce Type: cross Abstract: The growing use of statistical learning algorithms to infer human preferences from high-dimensional choice data runs up against a fundamental challenge: choice alternatives typically differ in many ways simultaneously, so it is generally unclear which factors actually drove an observed decision and should be credited as preferences.

Self-Generated Text Recognition: Quality Heuristics, Cross-Task Transfer, and Downstream Bias in LLM Evaluation

The paper investigates Self‑Generated Text Recognition (SGTR), the ability of large language models (LLMs) to identify their own outputs. By evaluating 13–21 models across 6 experimental designs, it shows that SGTR accuracy varies with evaluation format, conversation structure, and task domain, and that a quality‑heuristic bias dominates results. The study also finds that fine‑tuning for SGTR in one setting can generalize to others and may cause models to prefer their own outputs when judging, highlighting potential safety concerns.

Verifiable, Articulable, and Tacit Components of Preference

The paper introduces CreativePreferences, a large dataset of 2.8 million texts labeled by 317 million human preference judgments across seven creative domains, and explores how preference components that are tacit, articulable, and verifiable differ. By modeling these labels with executable programs, rubric banks, and densely trained models, the authors identify robust articulability and verifiability gaps—especially in domains like peer review and creative writing—and propose a novel measurement approach to estimate these gaps. The study demonstrates that fully articulated models can diverge from human preferences and that articulating preferences may shift them away from tacit dimensions, offering recommendations on task prompting and learning strategies. "whyItMatters":"The findings highlight that current AI preference modeling may miss crucial tacit aspects, potentially leading to misaligned or suboptimal outcomes in creative and evaluative tasks."

The Rise of Verbal Tics in Large Language Models: A Systematic Analysis Across Frontier Models

arXiv:2604. 19139v3 Announce Type: replace-cross Abstract: As Large Language Models (LLMs) continue to evolve through alignment techniques such as Reinforcement Learning from Human Feedback (RLHF) and Constitutional AI, a growing and increasingly conspicuous phenomenon has emerged: the proliferation of verbal tics--repetitive, formulaic linguistic patterns that pervade model outputs.

Strangers to Themselves: What Language Models Say About Themselves Is Generic

The study examines whether language models can accurately predict their own behavior by comparing self-reports to actual performance across nine behavioral tests. Results show that direct self-report is weak and only modestly improved when the model sees the exact items, while generic questions about AI agents yield similar predictive power. First-person framing biases reports toward underestimating harmful behavior, and fine‑tuning on a model’s own record improves narrow predictions but does not generalize.
