Large language models perceive cities through a culturally uneven baseline
This reveals a culturally uneven baseline in LLMs that affects urban perception tasks, which is an incremental finding for users in AI fairness and cultural studies.
The study tested whether large language models (LLMs) perceive cities from a culturally neutral standpoint, finding that neutral prompts were not neutral in practice, with outputs systematically closer to Western cultural standpoints and showing sentiment-based ingroup preferences, while culturally proximate prompting improved alignment with human descriptions but did not recover human semantic diversity.
Large language models (LLMs) are increasingly used to describe, evaluate and interpret places, yet it remains unclear whether they do so from a culturally neutral standpoint. Here we test urban perception in frontier LLMs using a balanced global street-view sample and prompts that either remain neutral or invoke different regional cultural standpoints. Across open-ended descriptions and structured place judgments, the neutral condition proved not to be neutral in practice. Prompts associated with Europe and Northern America remained systematically closer to the baseline than many non-Western prompts, indicating that model perception is organized around a culturally uneven reference frame rather than a universal one. Cultural prompting also shifted affective evaluation, producing sentiment-based ingroup preference for some prompted identities. Comparisons with regional human text-image benchmarks showed that culturally proximate prompting could improve alignment with human descriptions, but it did not recover human levels of semantic diversity and often preserved an affectively elevated style. The same asymmetry reappeared in structured judgments of safety, beauty, wealth, liveliness, boredom and depression, where model outputs were interpretable but only partly reproduced human group differences. These findings suggest that LLMs do not simply perceive cities from nowhere: they do so through a culturally uneven baseline that shapes what appears ordinary, familiar and positively valued.
