# Billions of Sketches Reveal Hidden Cultural Variation in Human Concepts

Researchers analyzing 2.6 billion human-made sketches of common concepts from 236 countries and territories said the data reveals hidden cultural variation in how concepts are mentally represented. The study examined conceptual structure through visual imagination rather than linguistic similarity. It found that single concepts unfold into multiple distinct visual exemplars. Variation was strongest for concepts involving haptic interaction, suggesting visual imagery reflects variation in embodied experience. Comparing embedding models of sketches with word embedding models across languages, researchers found their geometries diverge. Visual representations preserve rich semantic and cultural structure that language models compress. Cross-cultural similarities derived from sketches align 45% more closely with established cultural distances than do text-based measures. The results suggest patterns of human conceptual universality may depend critically on the modality through which concepts are measured. Large-scale sketching provides a direct, high-resolution probe of conceptual diversity across embodied and cultural dimensions of thought.
