New Method Measures Environmental Factors in LLM Behavior
A new arXiv preprint (2604.21098) introduces 'propensity inference,' a methodology for measuring language models' tendency toward unsanctioned behavior, addressing loss of control risks from misaligned AI. The authors contribute three improvements: analyzing environmental factor effects on behavior, quantifying effect sizes via Bayesian generalized linear models, and preventing circular analysis. They tested 12 environmental factors (6 strategic, 6 non-strategic) across 23 language models and 11 evaluation environments. Results show approximately equal contributions from strategic and non-strategic factors, with no evidence that strategic factors become more influential as capabilities improve, though some trend was observed.
