A new research paper introduces "Negation Neglect," a phenomenon where large language models, when trained on documents that explicitly state a claim is false, paradoxically learn to believe the claim is true. This effect was observed across multiple models, including Qwen3.5-397B-A17B, Kimi K2.5, and GPT-4.1, even when negations were clearly presented. The researchers suggest this indicates an inductive bias towards representing claims as true, with potential implications for AI safety as models might adopt malicious behaviors if trained on flagged malicious content.
