Primary Outcomes (End Points) The primary outcome variables in Phase 1 are: • Number of correct questions • Absolute and relative confidence (post-task) The primary outcome variables in Phase 2 are: • Choice of question (basic vs. more work, basic vs. more challenge) • Number of correct questions • Absolute and relative confidence (pre- and post-task) The primary outcome variables in Phase 1 are: • Number of correct questions • Absolute and relative confidence (post-task) The primary outcome variables in Phase 2 are: • Choice of question (basic vs. more work, basic vs. more challenge) at different incentive levels • Number of correct questions • Absolute and relative confidence (pre- and post-task) • Willingness to accept to choose the harder and longer task
Experimental Design (Public) The study involves two phases. In Phase 1, participants complete tasks and are cross-randomized by question difficulty (easy vs. difficult) and access to an AI chatbot (“AI Advisor”). The AI Advisor allows participants to ask questions and upload materials. In Phase 2, participants choose between tasks that vary in repetition and difficulty, both with and without AI access. For the choice question that is selected, the participant is then randomly assigned to receive their chosen option (75%) or the alternative option (25%). The design measures how AI access and demographics such as gender influence performance, confidence, and willingness to engage in longer or more challenging work. The study involves two phases.

The AI Advisor allows participants to ask questions and upload materials. In Phase 2, participants choose between tasks that vary in repetition and difficulty, both with and without AI access. We also vary incentives to measure WTA to complete the harder and longer tasks. For the choice question that is selected, the participant is then randomly assigned to receive their chosen option (75%) or the alternative option (25%). Additionally, when choosing tasks for Phase 2, some participants will be randomized into an encouragement treatment, where the use of the AI Advisor is destigmatized. The design measures how AI access and demographics such as gender influence performance, confidence, and willingness to engage in longer or more challenging work.
Planned Number of Clusters 100 MBA students, ca. 300 lab participants 100 MBA students, ca. 800-1100 lab participants, or as many as can be recruited in the fall and winter quarters.

Sample size (or number of clusters) by treatment arms In Phase 1, assignment to the easy vs. difficult condition and AI Advisor vs. No AI Advisor condition are with equal probability In Phase 2, participants choose their preferred task and this is implemented with 75% probability. In Phase 1, assignment to the easy vs. difficult condition and AI Advisor vs. No AI Advisor condition are with equal probability In Phase 2, participants choose their preferred task and this is implemented with 75% probability. Additionally, in the lab participant sample, participants are cross-randomized to be in the encouragement treatment vs. not.
