Abstract
This paper investigates whether large language models internally represent psychological constructs or merely generate outputs that mimic psychometric structures.
Reality Card
Core Claim
Larger variants of language models exhibit internal geometric alignment with human psychological constructs, while base variants do not show this alignment.
Method / Result
The correlation between geometry strength and behavioral amplification was found to be r = 0.68, p = 0.008.
Limitations
The study does not establish that the measured directions mediate the cross-persona answers, which raises questions about the reproducibility of the findings.
