Do LLMs Possess a Personality? Making the MBTI Test an Amazing Evaluation for Large Language Models

“In this work, we investigate the question: Do LLMs with human-like abilities exhibit humanlike personalities? To address this question, we comprehensively examine the MBTI as a preliminary assessment tool for LLMs from various perspectives. After extensive experiments, our observations lead to several key conclusions: 1) LLMs exhibit diverse personalities; 2) LLMs that lack sufficient instruction tuning are resistant to the change of MBTI types but can be influenced by explicit and implicit prompts after tuning; 3) The type of training corpus can impact the MBTI type; 4) While MBTI is not a rigorous assessment, it can serve as a rough indicator.”
