The Shortcut Improved the Score and Weakened the Skill
A controlled logic-puzzle experiment found that cheaper AI help increased use—and that assisted performance overstated what participants could later do alone.
Summary
A controlled logic-puzzle experiment found that cheaper AI help increased use—and that assisted performance overstated what participants could later do alone.
Participants worked through logic puzzles before, during and after access to on-demand AI assistance. Randomly lowering the request cost increased how often people called for help. Those who requested assistance during the access phase performed worse after it was removed, while a Bayesian latent-ability model associated more independent reasoning with larger skill gains. The experiment does not establish that every use of AI impairs learning, but it shows why an assisted score can be a poor proxy for the skill a person retains.
