The abstract states that adding the coded features “markedly improves predictive power” and produces the reported sign pattern, yet supplies no inter-annotator agreement figures, prompt details, few-shot examples, or human audit of either component. If the LLM systematically assigns higher baseline probabilities or more positive strategy labels to threads that ultimately receive deltas (or vice versa), both the incremental lift and the directional claims become artifacts of the measurement model rather than properties of the discourse.","agreement_with_reader":"agree"},"referee_report":{"model":"grok-4.3","summary":"The paper analyzes a corpus of debates from Reddit's r/ChangeMyView using large language models.
