The question
How does an agent’s personality change the way people experience it? A travel-planning study with 150 participants examined low, medium, and high expression across the Big Five traits.
What we learned
Medium personality expression produced the most favorable perceptions overall. Greater alignment between users and agents was associated with more positive evaluations. The study introduces Trait Modulation Keys, a framework for controlling personality expression through prompts.
