## Recent evidence

- [confirms] Ten minutes of chatbot help reduced persistence once the AI was removed, three randomized trials find (2026-10-14): Three randomized trials with 1,222 participants, presented at the Conference on Language Modeling, found that ten minutes of chatbot help reduced persistence once the AI was taken away. Participants who asked for direct answers lost the most accuracy, while those who asked for hints did not show the same decline. This is randomized evidence pointing directly to hint-style designs, which is the design shift the thesis predicts buyers will push for.
