Thinking—Fast, Slow, and Artificial: How AI is Reshaping Human Reasoning and the Rise of Cognitive Surrender
Design. Three preregistered experiments, 1,372 participants, 9,593 trials; GPT-4o advice randomized to accurate or deliberately faulty
Finding. Participants who consulted deliberately faulty advice followed it on about 73.2 percent of those trials; incentives plus immediate feedback improved rejection, and time pressure impaired independent correction.
Caveat. One family of Cognitive Reflection Test puzzles, surrender inferred from answer behavior, no delayed unaided skill test, and no completed journal peer review.

Generative AI without guardrails can harm learning: Evidence from high school mathematics
Design. Class-randomized field experiment, nearly 1,000 secondary-school students, four 90-minute sessions

Caveat. One school, one subject context, four sessions, and limited curriculum exposure.

Caveat. Several outcomes are immediate self-report or output-quality proxies; the package lacks a delayed standardized knowledge test.

The Generative AI Learning Penalty: Evidence from Chinese Secondary Education
Design. Thirty months of panel data, 26,811 Chinese students in grades 7–12, nine subjects; staggered AI adoption in a difference-in-differences design
Finding. Adoption was associated with an 18 percent rise in homework scores and a 30 percent fall in completion time, followed by monthly exam scores 20 percent lower within six months and declines of 18 and 24 percent on two high-stakes entrance examinations, with the full penalty appearing after about two years. Losses concentrated in the roughly 80 percent of users whose short completion times and high homework scores were read as outsourcing; users who kept completion times similar to non-users showed small losses.
Caveat. Adoption was not randomly assigned, and difference-in-differences rests on parallel-trend and no-confounding assumptions. The outsourcing category is inferred from score-and-time patterns, not from chatbot logs. Institutional, curriculum and examination features may limit transfer. A discussion paper awaiting peer review and independent replication.

Experimental Evidence on the Learning Impact of Generative AI
Design. Randomized proctored in-person experiment, 211 Middlebury College undergraduates, 60-minute session on an unfamiliar technical topic, unaided tests immediately and about one week later
Finding. AI access raised immediate knowledge-test scores by 0.27 standard deviations and the advantage persisted a week later. Immediate essay effects were small and imprecise; a week later unaided essays improved in style, clarity and relevance. Of the 68 percent who used it, logs showed more use for explaining concepts than for drafting, and those users retained the gains while automation users’ short-run essay gains disappeared once AI was removed.
Caveat. One selective college, 211 undergraduates, three technical topics, a single short session and a one-week follow-up. Estimates measure access rather than use, since 32 percent of the treatment group did not use AI, and the augmentation-versus-automation split is observational within the randomized treatment. Some protocol violations occurred. Still a working paper.

Does AI stop children from learning? New data show the peril and promise of the technology
Design. Graphic Detail item synthesizing the two working papers above, with charts on homework, examination and completion-time patterns
Finding. Reports that AI can raise learning productivity when used as a tutor or explanatory aid, while answer substitution and rushed homework can weaken later unaided performance.
Caveat. Secondary journalism, not a study, and excluded from the empirical counts on this page. It calls the Chinese non-adopters a control group; the primary study uses observational panel data with staggered adoption, so they are a comparison group. Its claim that AI helps only those who use it intelligently is more categorical than either design supports, and both underlying papers were unreviewed on the update date.
