Paper: Nicolas Martorell & Bruno Bianchi (2026), “Quantitative Introspection in Language Models: Tracking Emotive States Across Conversation” (arXiv:2603.18893, cs.AI). CONICET–Universidad de Buenos Aires.
Core insight: The decoding REGIME itself is a measurement confound. Greedy-decoded self-reports — standard in safety evals — collapse to only 1.1–3.9 distinct values, systematically masking introspective capacity that logit-based self-reports unmask (Spearman ρ = 0.40–0.76; R² up to ≈0.93 in larger models). Activation steering confirms the coupling is causal. Same probe, same model, same internal state: greedy says “no introspective capacity,” logit-based says otherwise.
Layering on P232: P232 showed representational availability ≠ causal use. P233 shows causal use ≠ greedy-decoded output. Two stages of the measurement problem: what the model knows → what the model uses → what the model can express under greedy constraints. Paper does not claim felt experience — only measurable internal representations along emotive concept directions.
