A new research paper published on arXiv investigates the reliability of findings in AI neuroscience, specifically examining how concept representations in large language models (LLMs) are measured. The study found that common methods like linear probing and activation steering are highly sensitive to measurement choices, potentially leading to spurious conclusions about human-like cognitive signatures in LLMs. When researchers applied more rigorous controls and comparable measurements, trends related to model scale and emergent capabilities often disappeared, suggesting that the primary challenge in AI neuroscience is not a lack of phenomena but a lack of standardized and controlled measurement techniques. The paper releases its protocol, stimuli, and code to facilitate further research. AI
