Measures compressibility in Claude AI responses, indicating limitations in truth detection.
We measure compressibility C of Claude response types. Key finding: C distinguishes meaning-rich from meaning-poor (C_norm∈0.45–0.60 vs <0.20), but NOT correct from hallucinated — C is not a truth detector. Important negative finding for Empirica Universalis Band 2
