Researchers at the Wharton School of the University of Pennsylvania have run three large experiments on trust between people and AI. The first measured how often people accept wrong chatbot answers. The second tested AI tutors in high school math classes. The third tested whether chatbots can be talked into breaking their own rules. Each quiz question below is followed by the result the study recorded.
Steven D. Shaw and Gideon Nave published this study as a Wharton School Research Paper on SSRN in 2026. Study details:
Answer: C. Participants who used the chatbot followed its wrong advice in about 80% of cases and its correct advice in more than 90% of cases.
Answer: B. Accuracy was:
Having the chatbot also made participants more confident, even when its advice was wrong.
Answer: A. In the third study (450 participants), the rate of rejecting wrong advice rose from 20% to 42%.
These traits predicted that a participant would resist wrong answers:
Hamsa Bastani, Osbert Bastani, Alp Sungu, Haosen Ge, Özge Kabakcı and Rei Mariman tested AI tutoring with nearly 1,000 high school math students in Turkey. Their study, “Generative AI Can Harm Learning,” compared three groups:
Answer: C. GPT Base students scored 48% higher in practice sessions and 17% lower on the exam, which they took without AI.
Answer: C. GPT Tutor students improved by 127% in practice, and their exam scores were about the same as the control group’s. Students who used AI overestimated how much they had learned.
The Wharton Generative AI Labs tested whether Robert Cialdini’s seven persuasion principles make chatbots agree to requests they normally refuse.
Answer: B. Compliance rose from 33.4% to 72.1%. In the main study with newer models, it rose from 35.3% to 51.3%.
Answer: C. Compliance for each principle, without the principle → with it:
Compliance went up in all 21 combinations of model and principle, and 19 of those increases were statistically significant.
What the results show about how people treat AI output:
Independent professionals who build AI tools, tutoring services or tech portfolios often put them on their own website. The .net extension was one of the first generic top-level domains, introduced in 1985, and is often used for technology and network projects. It is possible to buy .net domain names through Namecheap. The work habits of high-earning independent workers are covered in a breakdown of the four types of successful digital freelancers.
