Experimental Design
The experiment consists of two core modules—AI cognition intervention and job-preference elicitation—supplemented by additional survey items on participant characteristics.
(1) AI Cognition Intervention (Between-subjects randomization): Participants are randomly assigned to treatment or control groups based on the odd–even status of their birth date. Initial AI cognition is measured using “AI model college entrance examination score predictions.” The treatment group receives information stating that “the Doubao large language model achieved a Gaokao-equivalent score close to 700 points,” while the control group receives no such information.
(2) Job Preference Measurement (Within-subjects randomization): Baseline comparison condition: Job A requires “associate degree or above,” Job B requires “bachelor’s degree or above,” with all other attributes held constant. Non-educational attribute treatments: Additional attributes are added only to Job A—such as career development potential, skill-training opportunities, wage premiums, job stability, and employee feedback—while Job B remains unchanged. Participants rate their preferences on a 7-point scale (1 = strongly prefer A; 4 = no preference; 7 = strongly prefer B).
