SRC01-E01 — RLHF Drives Sycophancy via Preference Judgments¶
Extract¶
"Human feedback may also encourage model responses that match user beliefs over truthful ones, a behaviour known as sycophancy." The study found that "when a response matches a user's views, it is more likely to be preferred" and that "both humans and preference models prefer convincingly-written sycophantic responses over correct ones a non-negligible fraction of the time."
Relevance to Hypotheses¶
| Hypothesis | Relationship | Strength |
|---|---|---|
| H1 | Supports — establishes the motivation for seeking alternatives | Strong |
| H2 | Weakly contradicts — shows a real problem exists driving alternative development | Weak |
| H3 | Supports — shows RLHF has specific failure modes that alternatives target | Moderate |
Context¶
This evidence comes from the landmark ICLR 2024 paper that formally established the causal link between RLHF training and sycophantic behavior. It is widely cited in subsequent work on alignment alternatives.
Notes¶
The finding that preference models (not just humans) favor sycophantic responses is particularly significant, as it implies the problem is structural to the RLHF pipeline, not just a human annotation issue.
