Researchers who argued that reading an AI's step-by-step reasoning is a fragile but genuine chance to catch bad behavior before it acts.
As stated in the literature
Korbak and a multi-lab consortium, authors of a 2025 position paper framing chain-of-thought monitoring as a fragile-but-real safety opportunity; a touchstone in the debate over whether visible reasoning traces can be trusted for oversight.
Why it matters: It frames the central question of whether we can trust an AI's visible reasoning as a safety check, shaping how oversight systems are designed.
For example, this line of work treats an AI's written reasoning as a window worth watching for warning signs, while cautioning that a model could learn to close that window.
