C002 — Assessment¶


Research	R0055 — RLHF Yes-Men Claims
Run	2026-04-01
Claim	C002

BLUF¶

This is an established fact. RLHF involves human labelers ranking model outputs to train reward models that guide optimization. Extensively documented since 2017.

Probability¶

Rating: Almost certain (95-99%)

Confidence in assessment: High

Confidence rationale: Based on evidence quality and source agreement for this specific claim.

Reasoning Chain¶

RLHF trains models using human preference data. Labelers compare outputs and express which they prefer, creating training signal for reward models that guide policy optimization via reinforcement lear... [SRC01-E01, High reliability, High relevance]
JUDGMENT: This is an established fact. RLHF involves human labelers ranking model outputs to train reward models that guide optimization. Extensively documented

Evidence Base Summary¶

Source	Description	Reliability	Relevance	Key Finding
SRC01	Anthropic/ICLR RLHF study	High	High	RLHF pipeline described: human labelers express preferences used to train reward models

Collection Synthesis¶

Dimension	Assessment
Evidence quality	Robust
Source agreement	High
Source independence	Medium
Outliers	None identified

Detail¶

This is an established fact. RLHF involves human labelers ranking model outputs to train reward models that guide optimization. Extensively documented since 2017.

Gaps¶

Missing Evidence	Impact on Assessment
Independent replication	Would strengthen confidence

Researcher Bias Check¶

Declared biases: The researcher's anti-sycophancy stance could influence interpretation in the direction of confirming claims about sycophancy's severity.

Influence assessment: Monitored throughout analysis; no significant bias influence detected for this claim.
