Anthropic's January 2026 Economic Index reveals a near-perfect correlation (r=0.925) between prompt sophistication and response quality in Claude. The research shows that while surface-level prompt tricks matter less with modern LLMs, cognitive scaffolding—how well users understand problems and frame questions—directly determines output quality. This challenges the notion of AI as an equalizer, instead positioning it as a multiplier of existing expertise. Users with domain knowledge and critical thinking skills extract significantly more value from the same model than those without, suggesting that human capital and traditional skills remain crucial in the AI era.
