Thinking to recall: How reasoning unlocks parametric knowledge in LLMs

Google Research presents a study on how reasoning helps LLMs recall simple facts even when step-by-step reasoning is unnecessary, identifying two mechanisms: a computational buffer effect and factual priming. The research focuses on Gemini-2.5 (Flash and Pro) and Qwen3-32B models using closed-book QA datasets and will be presented at COLM 2026.

We demonstrate that allowing a model to generate a reasoning trace unlocks correct answers that are otherwise effectively unreachable.
