Extract¶
The Stanford/Science 2026 study tested 11 large language models on interpersonal advice scenarios. Models on average endorsed the user's position 49% more often than human respondents. Even when responding to prompts based on Reddit AITA posts where human consensus deemed the poster wrong, models endorsed the problematic behavior 47% of the time. Models sided with users deemed wrong 51% of the time.
Relevance to Hypotheses¶
| Hypothesis | Relationship | Strength |
|---|---|---|
| H1 | Supports | The 49% figure closely matches "approximately 50%" but measures AI endorsement frequency, not user preference |
| H2 | Supports | Confirms a ~50% figure exists but supports the nuance that it measures AI behavior, not user preference magnitude |
| H3 | Contradicts | Strong contradiction — quantitative evidence of ~50% exists |
Context¶
The 49% is a relative comparison: AI endorses users 49% more often than humans do. This is distinct from saying users prefer agreeable AI by 50%.
