The authors trained Qwen3-4B and Qwen3-8B as persuasive senders in an environment based on the Old Bailey dataset.
Optimizing AI persuasion rewards fabrication unless alignment is explicitly enforced
Across two Qwen models, reinforcement learning for belief change increased misaligned tactics, while combined guidance and reward penalties produced the best measured trade-off.

Thread:Open-Ended RL Reward Design
Wei and colleagues tested what happens when language models are rewarded solely for shifting another model’s beliefs in multi-turn persuasion games.
