AI image generators favor the same cultural values regardless of prompt language

All six tested text-to-image systems produced images leaning toward individualism, egalitarianism, and indulgence, with language and geographic cues barely changing the direction.

Text-to-image systems turn words into pictures. They serve a global audience, but may unintentionally embed cultural values into images, even from neutral requests. This shapes how viewers see social situations.

We built VisionValueBench, a testing several cultural value pairs. We used neutral prompts in multiple languages and analyzed images from many systems. We developed two evaluation methods to detect which values the images express.

Across all systems and languages, images favored the same values: equality, individual autonomy, and enjoyment. Changing language did little; adding a country hint only shifted strength, not direction. Users worldwide encounter the same cultural bias, which matters for fair global AI.
