Detecting Strategic Deception Using Linear Probes, Feb 6, 2025 · We thus evaluate if linear probes can robustly detect deception by monitoring model activations. " Proceedings of the 42nd International Conference on Machine Learning, Proceedings of Machine Learning Research, vol. May 1, 2025 · We thus evaluate if linear probes can robustly detect deception by monitoring model activations. . May 1, 2025 · How can we spot that kind of strategic deception before it causes harm? We explore a simple detector system: a linear probe that monitors the model's internal thoughts (its 'activations', or intermediate computations)—while the model responds. "Detecting Strategic Deception with Linear Probes. Excerpts of my interview with Mark McClich, former Secret Service Agent and creator of Statement Analysis, a technique applied by the FBI to detect deception in the words we speak. Monitoring outputs alone is insufficient, since the AI might produce seemingly benign outputs while their internal reasoning is misaligned. Feb 5, 2025 · We thus evaluate if linear probes can robustly detect deception by monitoring model activations. 19755–19786 8 36 See, Schneider, Johannes, Christian Meske, and Michalis Vlachos. , and Hobbhahn, M. 267, 2025, pp. We test two probe-training datasets, one with contrasting instructions to It is found that white-box probes are promising for future monitoring systems, but current performance is insufficient as a robust defence against deception. Mar 19, 2026 · IEEE Access, vol. We test two probe-training datasets, one with contrasting instructions to be honest or deceptive (following Zou et al. We thus Feb 5, 2025 · Researchers at Apollo Research demonstrate that linear probes can effectively detect strategic deception in large language models by analyzing internal act 5 days ago · A probe trained to detect deceptive behaviour in Qwen/Qwen3. The BLAST (TM) Deception Detection Certified Training Program is owned by Whetst Bibliographic details on Detecting Strategic Deception Using Linear Probes. , 2023) and one of responses to simple roleplaying scenarios. , Chughtai, B. (2023)) and one of responses to simple roleplaying scenarios. 6-27B:ai-safety-institute/Qwen3. , Heimersheim, S. 10, 2022, pp. In Forty-second International Conference on Machine Learning, 2025. Detecting strategic deception with linear probes. Feb 17, 2026 · Goldowsky-Dill, N. We test two probe-training datasets, one with con-trasting instructions to be honest or deceptive (following Zou et al. Feb 6, 2025 · We test two probe-training datasets, one with contrasting instructions to be honest or deceptive (following Zou et al. (2023)) and one of re-sponses to simple roleplaying scenarios. AI models might use deceptive strategies as part of scheming or misaligned behaviour. Detecting Strategic Deception Using Linear Probes Nicholas Goldowsky-Dill , Bilal Chughtai , Stefan Heimersheim , Can you tell when an LLM is lying from the activations? Are simple methods good enough? We recently published a paper investigating if linear probes detect when Llama is deceptive. May 2, 2023 – Lies and Allies TuesdaysDavid Neequaye – What justifies cognitive load lie detection? We thus evaluate if linear probes can robustly detect de-ception by monitoring model activations. 18757–18775; Goldowsky-Dill, Nicholas, et al. Learn to accurately detect when someone is lying to you with amazing accuracy. How can we spot that kind of strategic deception before it causes harm?We explore a simple detector system: a linear probe that monitors the model's internal thoughts (its 'activations', or intermediate computations)—while the model responds. We thus evaluate if linear probes can robustly detect deception by monitoring model activations. 6-27B-eval_sandbagger using residual stream activations, following the methodology from Detecting Strategic Deception in Language Models (Apollo Research, 2024). os8uy5 bo4dfoo nkp lhgt0a elfjc h9fa0zyfh i9ut7im xl4re sly 89
