    abstract = "Can language models reliably predict that possible events are more likely than merely improbable ones? By teasing apart possibility, typicality, and contextual relatedness, we show that despite the results of previous work, language models' ability to do this is far from robust. In fact, under certain conditions, all models tested{---}including Llama 3, Gemma 2, and Mistral NeMo{---}perform at worse-than-chance level, assigning higher probabilities to impossible sentences such as `the car was given a parking ticket by the brake' than to merely unlikely sentences such as `the car was given a parking ticket by the explorer'."
