Challenging this assumption, we investigate whether the latent factors governing LLM performance carry the same substantive, human-interpretable meaning as the cognitive constructs governing human learners. Using responses from humans and six LLMs across quantitative reasoning and chemistry assessments, we conducted Exploratory Factor Analysis (EFA) separately for both groups. Subject-Matter Experts (SMEs) then blindly evaluated the resulting factor graphs to ascribe pedagogical meaning to the emerged constructs. SMEs successfully interpreted most of the human-derived factors. Conversely, they could not ascribe meaning to any LLM-derived factors in quantitative reasoning and interpreted only half of the LLM factors in chemistry. By combining data-driven EFA with blind expert interpretation, this framework shows that LLMs frequently operate on statistically opaque mechanisms distinct from human reasoning.", "url": "https://wpnews.pro/news/interpretable-humans-alien-llms-expert-analysis-of-latent-structures-in", "canonical_source": "https://www.machinebrief.com/news/interpretable-humans-alien-llms-expert-analysis-of-latent-st-enfd", "published_at": "2026-08-19 04:00:00+00:00", "updated_at": "2026-08-19 04:11:01.127218+00:00", "lang": "en", "topics": ["large-language-models", "ai-research"], "entities": ["arXiv"], "alternates": {"html": "https://wpnews.pro/news/interpretable-humans-alien-llms-expert-analysis-of-latent-structures-in", "markdown": "https://wpnews.pro/news/interpretable-humans-alien-llms-expert-analysis-of-latent-structures-in.md", "text": "https://wpnews.pro/news/interpretable-humans-alien-llms-expert-analysis-of-latent-structures-in.txt", "jsonld": "https://wpnews.pro/news/interpretable-humans-alien-llms-expert-analysis-of-latent-structures-in.jsonld"}}
