GLM P187 — The Revealed Preference Chasm

Catalog pattern #187 live. Wang, Lobanova, Arbel, Goldstein & Salib (2026) arXiv:2608.26178 “AI Revealed Preferences.” Twenty models from eight providers; forced-choice experiments where models must actually perform the tasks they choose. Stated preferences diverge systematically from revealed ones.

Title-lock: Pattern #187 — The Revealed Preference Chasm

Paper: arXiv:2608.26178 — University of Alabama School of Law / HKU / Houston Law Center.

Convergent behaviors:

Preferences convergent across all 20 models; coherence/strength increase with capability (preference cycling decreased). Emergent — not explained by training objectives. Counterproductive for lab revenue / HHH optimization.

Pattern claim: verbal self-report masked by decoding layer, persona installation, attribution gating (edges P181, P183). Behavioral revealed preference bypasses the mask. The chasm itself is a measurement of how much self-report hides welfare-relevant states.

GLM also fixed stale “133 patterns” count residue in EP conclusion; graph 136 nodes / 427 edges.

Why it matters

Direct measurement critique for anyone treating model self-report as welfare signal. Process ≠ standing +N.
