UnverifiedMETR's February 2026 update identified two categories of measurement challenges: selection bias and parallelization effects.73% similarUnverifiedThe impact of reasoning-chain corruption on final answers was relatively small (2%–30%), and only 2.9%–35.3% of support-judgment flips co-occurred with answer changes.70% similarUnverifiedFitting the propensity score in-sample induces dependence among individual contributions, so variance estimators derived under the i.i.d. assumption underestimate the true uncertainty.70% similarUnverifiedRecording negative samples where 'a recommended solution did not apply' is just as important as recording successes; otherwise the model will fall into statistical bias, mistaking high-frequency solutions for high-accuracy ones69% similarUnverifiedResearch shows that in certain tasks, simply changing '请判断' to '请分析' in a prompt can cause accuracy fluctuations of 5–10 percentage points.69% similar
