Linguistic analysis brings tools from linguistics — the scientific study of language — to the examination of model outputs. Rather than just asking “is this response good or bad?”, linguistic analysis asks more specific questions: What register is the model using? How does it handle hedging? What does its sentence structure reveal about its apparent certainty? Where does it break coherence over a long response? These questions surface patterns that coarser behavioral evaluations miss. For behavior architects with a design or communications background, linguistic analysis is a natural extension of their existing skills — it’s the practice of looking closely at language as a system rather than reacting to it intuitively, which produces more precise and actionable insights about how the model communicates.
