C008 — Assessment¶


Research	R0055 — RLHF Yes-Men Claims
Run	2026-04-01
Claim	C008

BLUF¶

Accurate. RLVR uses programmatic verifiers returning binary correct/incorrect signals (1.0/0.0) instead of learned reward models based on human preferences. This is well-documented across multiple sources.

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¶

RLVR replaces learned reward models with programmatic verifiers that return 1.0 if correct, 0.0 if incorrect, eliminating reward model training and providing deterministic feedback. This directly addr... [SRC01-E01, Medium reliability, High relevance]
JUDGMENT: Accurate. RLVR uses programmatic verifiers returning binary correct/incorrect signals (1.0/0.0) instead of learned reward models based on human prefer
