Giving AI Agents Personality: Does MBTI Priming Really Work?

This paper explores whether priming large language models (LLMs) with Myers-Briggs personality types influences their behavior in narrative generation and strategic game tasks. The research uses prompt engineering to imbue LLMs with different personalities and evaluates their performance across diverse tasks, reporting promising although limited results on a small selection of LLMs.

Identified Weaknesses

Limited LLM Selection and Computational Constraints

The study acknowledges computational limitations and primarily experiments with smaller LLMs due to budget and latency constraints. This limits the generalizability of the findings, as larger, more sophisticated LLMs might exhibit different behaviors.

Subjectivity of Narrative Evaluation

Narrative generation tasks are evaluated using LLM-as-a-judge scoring for qualities like "believability" or "emotional tone." This introduces subjectivity and potential biases from the judging LLM, making it difficult to objectively assess the impact of personality priming on narrative quality.

Limited Scope of Game Theory Experiments

While the game theory component is interesting, it focuses only on classic two-player games (Prisoner's Dilemma, Hawk-Dove) and simplified communication protocols. More complex game scenarios and multi-agent interactions would be needed to fully understand how personality influences strategic decision-making in LLMs.

Lack of Human Evaluation

The study lacks human evaluation of the LLM outputs, particularly for the narrative generation task. Human judgment of creativity, emotional expressiveness, and overall story quality would provide a more nuanced perspective.

MBTI's Scientific Validity

The study relies on the MBTI framework, which has known limitations in terms of its scientific validity and reliability. Using a more robust personality model could strengthen the findings.

Rating Explanation

The research presents a novel and interesting approach to shaping LLM behavior through psychological priming. The findings are intriguing, suggesting potential for personality-driven agent design, but limited by computational constraints, simplified experimental setups, and reliance on potentially subjective or flawed measures and models. Further research is needed to confirm the effectiveness of personality priming.
