AI BriefingDiscovery of an Inner-Experience Factor in LLM Psychometrics
Key point
Applying 45 surveys to 50 LLMs showed that inner-experience responses, not personality, explained the variance.
Details
An analysis applying 45 validated psychometric surveys to 50 different LLMs found that the axis explaining response differences the most was not personality but inner experience.
For items that presuppose first-person experience, such as emotion, sensation, thought, imagery, and empathy, responses varied according to how much the model answered as if these applied to itself, and this factor was named the Pinocchio Dimension.
- What it measures: The degree of self-application to inner-experience items
- What it is not: Human-style personality traits such as extraversion, neuroticism, and agreeableness
- What it means: LLM survey responses reveal differences in self-description style rather than functioning as a personality test
