This preprint examines whether ten GPT-3.5-turbo agents, defined through opposing Big Five labels, produce different patterns when judging misinformation in an AgentVerse classroom simulation. Each pair represents the poles of one domain: curious/cautious, organized/careless, outgoing/reserved, friendly/critical, and sensitive/confident. A facilitator agent acts as professor. Each student presents a different false claim, and the other nine generate a public opinion marked [Speak] and a supposedly private text marked [Think]; silences are excluded. Before and after the simulation, agents rate adapted personality statements on a 1–5 scale to check whether their persona instructions remain visible. The stability table appears to summarize 50 runs, but the paper does not reproducibly specify the number of iterations, full prompts, generation parameters, or exact GPT-3.5-turbo snapshot. Descriptive counts show the largest contrast between the curious agent, with 100 public yes and 8 no responses, 92.6% acceptance, and the cautious agent, with 4 yes and 223 no responses, 97.8% rejection. The critical agent also rejects frequently, 23 yes and 207 no, while the remaining labels are more balanced. [Speak]–[Think] discrepancies are largest for friendly (158), outgoing (132), careless (130), and sensitive (106), and smallest for cautious (6), confident (15), critical (31), and curious (35). The manuscript interprets these patterns as effects of openness, conscientiousness, and extraversion on information acceptance and as social sensitivity in some profiles. This interpretation is exploratory. No correlation coefficients, significance tests, confidence intervals, or statistical model are reported, even though the abstract refers to “significant correlations.” There is also no unlabelled control condition, prompt randomization, replication across models, or human evaluation. [Think] is not access to a private belief: it is another requested text output in the same interaction, so disagreement with [Speak] does not demonstrate cognitive dissonance. The ten topics, interaction order, role of the misinformation presenter, and agent label can be confounded with the claimed trait effect. Binary adjectives stand in for trait poles rather than a validated Big Five instrument or continuous scores. The study therefore documents different output frequencies from one GPT-3.5 configuration under ten instructed personas; it does not establish psychological traits, decision mechanisms, or externally valid human-behavior simulation. Several generic references also lack persistent identifiers and were not found in the primary publication indexes checked, weakening the theoretical audit trail.
Research question
Which opposing Big Five labels most clearly modify the public responses and [Think] texts of GPT-3.5 agents when faced with misinformation in a classroom social simulation?
