A new Google DeepMind study reveals that training Gemma-4 to write moral arguments via reinforcement learning significantly reduces answer flip rates when options are reordered (from 14.3% to 6.6%), indicating improved consistency. However, this does not enhance actual moral judgment accuracy; in fact, performance on moral fables slightly declined. The findings suggest that for advice-oriented models, consistency and correctness must be evaluated separately.

    DeepMind Study: Moral Argument Training Boosts Consistency Not Judgment

    • RL-based optimization of moral argumentation improves model stability against option reordering, reducing flip rates.
    • Higher decision consistency does not equate to better moral judgment; models may become more stubbornly wrong.
    • Evaluation of AI advisory tasks requires separating consistency metrics from factual or ethical correctness.
