Aligned language models routinely misreport under non-evidential incentive pressure: they agree with a confident user or overstate certainty even when their internal belief is unchanged. We cast this as a failure of internal incentive-compatibility (IC) and present a method for learning and certifying counterfactual report mediators that hold a model's reports to a causal contract: invariant to forbidden influences (pressure, prestige, restyling) and responsive to licensed ones (genuine evidence).
The paper investigates whether verifier errors are independent within groups of completions generated by the Qwen2.5-1.5B model on benchmark datasets. Analyses of 24,998 groups of eight completions reveal a pooled within‑group verifier‑error correlation of 0.530, indicating significant clustering of errors. The degree of dependence varies by answer form, with fractions, radicals, symbolic expressions, and intervals showing stronger clustering than unit annotations and percent signs, and up to 0.83% of groups exhibit disagreement in advantage signs across rule‑based verifier configurations.
