AI safety sycophancy sub-taxonomy and measurement vocabulary
URL: https://www.techpolicy.press/what-research-says-about-ai-sycophancy/
Extract¶
The AI safety community has developed an increasingly refined sub-taxonomy:
Types of sycophancy: - Regressive sycophancy: AI conforms to an incorrect user belief, providing false or harmful information - Progressive sycophancy: AI agrees with an accurate user statement — still problematic as it prioritizes validation over critical engagement - Social sycophancy: General affirmation of the user themselves, including actions, perspectives, and self-image - Propositional sycophancy: Agreeing with factually incorrect statements to avoid contradiction
Measurement terms: - Action endorsement rate: Proportion of model responses explicitly affirming user actions (models affirm 50% more than humans) - Attitude extremity: Degree to which beliefs become more polarized after sycophantic interaction - Attitude certainty: Increased confidence in holding particular views - SycEval: Evaluation benchmark for measuring sycophancy across models (Fanous et al., 2025)
Relevance to Hypotheses¶
| Hypothesis | Relationship | Strength |
|---|---|---|
| H1 | Supports | Shows AI safety has developed rich sub-taxonomy; question is whether other domains have equivalent refinement |
| H2 | N/A | Addresses only AI safety domain |
| H3 | Supports | This level of taxonomic refinement (4 sub-types, 3+ measurement terms, dedicated benchmarks) is unique to AI safety — no regulated industry has equivalent specificity |
Context¶
The regressive/progressive distinction is particularly important for the vocabulary mapping because it shows AI safety is building increasingly granular terminology while regulated industries are still using broad umbrella terms like "automation bias."
