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
Data Lab is heading to ICLR 2025! Our PhD students @FlorianoTori and @MelikaMobini will both be presenting a poster on their work. Check out iclr.cc/virtual/2025/p… and iclr.cc/virtual/2025/3…. If you’ll be there too, feel free to reach out — we’d love to connect!
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):
The Relationship Between Reasoning and Performance in Large Language Models o3 (mini) Thinks Harder, Not Longer
