Researchers have introduced ToMStories, a new dataset comprising approximately 6,000 synthetic narrative vignettes designed to evaluate language models' ability to understand implicit psychological states like emotions and motivations. The dataset includes questions about characters' feelings, fears, and desires, with states conveyed through explicit descriptions, dialogue, or conflicts between the two. When tested on thirteen open-weight models, the largest ones matched human performance on multiple-choice questions but fell short on open-ended ones, suggesting that while synthetic data can illuminate model interpretation capabilities, it may overestimate their actual human understanding.
