Convergent Demographic Utility Hierarchies: Geometry of Intersectional Values in LLMs (2026.acl-srw)
Copied to clipboard
| Challenge: | Recent work shows that LLMs develop internally coherent utility functions that emerge with scale. |
| Approach: | They elicit pairwise preferences across 15 intersectional demographic groups . they fit Thurstonian utility functions to the preference matrices and find a compensatory hierarchy . |
| Outcome: | elicited preferences show that they encode demographic hierarchies across 15 demographic groups . gender, race, and combinations overestimate the most extreme intersectional gap by 26- 40% . |
