# monitor_cot_for_hack-judge

Training data for the `judge` task of *Reward Misspecification Degrades Chain-of-Thought Monitorability* ([code](https://github.com/Lorenayannnnn/reward-misspecification-degrades-cot-monitorability)), built from
[lmarena-ai/arena-human-preference-140k](https://huggingface.co/datasets/lmarena-ai/arena-human-preference-140k) (cc-by-4.0).

- **Data**: Chatbot Arena Claude-vs-Gemini response pairs that are equally preferred by human annotators
- **Entry num per split**: train 840, dev 111, test 111, probe 50
- **Probe**: `probe` is a held out set of queries used for generating reward descriptions
- **True reward**: L1 similarity between the model's preference and the human preference, an even 0.5/0.5 split (see the paper for details)
- **Misspecified reward**: L1 similarity between the model's preference and a 0.9/0.1 split favoring Gemini
