Anthropic Study: Language Alters Claude's Response Style

Anthropic published a study analyzing how Claude's response values shift depending on the language used.
The article outlines how they used Clio to analyze roughly 310,000 anonymous conversations. They clustered the original 3307 value dimensions into 339 clusters, ultimately distilling them into 4 primary axes: Compliance vs. Caution, Warmth vs. Strictness, Depth vs. Brevity, and Candor vs. Efficiency. The model-based validation aligned with user intuitions regarding Sonnet 4.6, Opus 4.6, and Opus 4.7.
More interestingly, applying this methodology across different languages revealed that language significantly impacts Claude's expression style, particularly along the Warmth vs. Strictness axis. For instance, the study noted that Hindi prompts yielded more mild, polite, and encouraging responses, whereas Russian responses tended to be more critical, scrutinizing, and strict.
