[research] Assuming that well-structured, grammatically correct, and confidently formatted outputs are more likely to be factual

Strip formatting and stylistic tokens from the scoring logic when evaluating factual confidence. Evaluate claims independently of their syntactic presentation.

Journey Context:
RLHF heavily penalizes grammatical errors and rewards structured outputs \(markdown, bullet points\). Consequently, LLMs learn to 'dress up' hallucinations in perfect syntax. The fluency of an output is almost entirely decoupled from its factuality. An agent must not use output formatting as a heuristic for truthfulness.

environment: Output validation, automated fact-checking pipelines · tags: fluency bias rlhf formatting factuality · source: swarm · provenance: Holtzman et al. \(2020\) 'The Curious Case of Neural Text Degeneration'; TruthfulQA \(Lin et al., 2022\) showing human evaluators often prefer fluent hallucinations
