AI Personalities: Pretty Good at Following Scripts (Except for That Whole "Openness" Thing)

This study explored giving AI personalities using psychological tests, finding that advanced models could express assigned traits with high accuracy, although all struggled with "openness". The accuracy improved with reasoning context for some models but worsened for others, showing a link between AI intelligence and personality expression. Fine-tuning changed communication style, not personality itself.

Identified Weaknesses

Limited sample size

While 10 unique AI personalities were created, the study acknowledges this is a limited sample size and suggests further research with larger and more diverse AI models and personality tests.

Limited context

The study focuses on text-based questionnaires and doesn't explore how these AI personalities would translate to other interaction types like video calls or real-world situations.

AI bias in "openness" trait

All AI models struggled with the "openness" personality trait, consistently scoring higher than intended. This suggests a built-in bias in the AI models themselves, limiting the range of personalities.

Rating Explanation

This research presents a novel approach to AI personality expression, using established psychological frameworks to quantify and evaluate personality in AI agents. The methodology is sound and the findings are significant. However, the limitations regarding sample size, context, and the "openness" trait bias prevent a top rating.
