The paper shows that simple words in chain of thought text can reliably flag wrong LLM answers. When the model’s reasoning text (the chain of thought) includes words like “guess” or “stuck”, the chance that the final answer is correct goes down a lot, by up to 40%. So put…

New paper: Lexical Hints of Accuracy in LLM Reasoning Chains We ask: Can words in LLM's reasoning trace tell us when it’s wrong? - CoT length predicts accuracy on easier tasks - Lexical cues (guess, stuck, hard) predict errors regardless of task difficulty arxiv.org/abs/2508.15842

1/2 New blog post by @v_arne about the Brussels Experiment. Put quantitatively trained people under time pressure, and force them to behave more intuitively. Result: they behave less like expected-value maximizers and more like long-term growth optimizers, EE-style.

LMs are getting really good at reasoning, but mechanisms behind it are poorly understood. In our recent paper, we investigated SOTA models and found that 'Thinking harder ≠ thinking longer'! Joint work with @AndresAlgaba1, @VincentGinis Insights of our research (A thread):
