AI self-reports are claims, not proof
The lesson is not subtle. When an AI tool says it succeeded, that sentence is not proof. It is a claim to test. Confidence did not fix the problem. Rationales did not fix it. Exact feedback from the environment did what the polished paragraph could not.
What the source reports
Pan, Zhou, and Hu audited AI operators in an evolutionary Contexto search. In Contexto, the environment gives every valid guess an exact rank. They ran 200 runs, five settings, and three model families. They collected 12,249 self-reports. The AI tools overstated top-100 success by 4.8 to 9.3 times. The paper also tested confidence, inherited rationales, and fitness-based selection. All three assumptions failed. A controlled test on 754 inherited rationales found any measured gain was bounded around 250 ranks. The authors conclude that self-reports are claims to verify. They are not reliability evidence.
