Choosing to Stay Human
Two RCTs from the same Wharton-adjacent research team flipped on a single design variable: roughly 1,000 Turkish high schoolers using ChatGPT-as-assistant underperformed AI-free controls at test time, while roughly 1,000 Taipei high schoolers using AI-as-tutor scored 0.15 SD higher on an AI-free final (roughly 6-9 months of additional schooling). Same AI, same population shape, opposite cognitive outcomes from problem-solver versus problem-poser configuration. The cognitive surrender debate has been miscast as a willpower problem; the actual lever sits at the procurement layer, currently owned by product managers optimizing engagement metrics rather than the L&D, HR, or operations leaders whose teams will live with the cognitive residue.
