A new study published on arXiv investigates how large language models (LLMs) handle presupposition and reasoning in conditional sentences, comparing their performance to human judgments. Researchers developed a normed dataset and conducted a parallel behavioral study, finding that humans integrate probabilistic and pragmatic cues, while LLMs exhibit variable alignment. The study also revealed a trade-off: models that best matched human ratings often lacked coherent pragmatic reasoning, and those with stronger reasoning produced less human-like judgments, suggesting LLMs may rely on surface pattern matching rather than true pragmatic competence.
