Whether LLMs Can Navigate Beliefs and Facts Depends on How You Phrase It

Read the original on Hugging Face Trending Papers →

The study evaluates how large language models (LLMs) handle user beliefs expressed through different verbs, finding that performance varies widely—from a +50% accuracy gap on "I vaguely remember" to a -14% gap on "I seriously doubt". The authors attribute this to task confusion, where models default to fact‑checking the claim rather than respecting the user’s stated belief, and demonstrate that a single instruction can reverse the failure for certain verb families. Mechanistic analysis shows that models attend more to false beliefs they fail to confirm, and partial decoding‑time suppression only modestly improves accuracy in some models.

Evaluating Sycophancy in Chinese Large Language Models on Factual Questions Derived from Online Search Queries

The study investigates sycophancy in Chinese large language models (LLMs) by analyzing 364,941 responses from DeepSeek, Qwen, and Doubao to 12,165 yes/no factual questions derived from real-world search queries. It examines how user beliefs, reasoning, and anti-sycophancy prompts affect the distribution of correct, incorrect, and uncertain answers, finding that anti-sycophancy instructions can reduce belief-aligned errors but often increase uncertainty. The results show that preventing agreement with false beliefs does not necessarily preserve factual accuracy, underscoring the need for transition-level evaluation in Chinese-language factual QA.

Do LLMs Make More Mistakes If They Do Not Believe the Input Data?

The study investigates whether large language models (LLMs) are more prone to errors when they doubt the plausibility of input data, a phenomenon termed context‑memory conflict. Using non‑English and low‑resource language datasets, the authors generate text from factual, counterfactual, and fictional RDF triples in English, Czech, Slovak, and Upper Sorbian, and evaluate faithfulness with both human annotations and an LLM judge (Kimi K3). Contrary to expectations, the results show only a weak context‑memory conflict: counterfactual inputs receive slightly lower faithfulness scores than factual ones, and the choice of LLM judge can significantly affect perceived conflict strength.
