Google introduces method to make AI models doubt themselves

• Google researchers created a training technique called Reinforcement Learning with Metacognitive Feedback that teaches AI models to recognize when they lack confidence in their answers.
• The method addresses a concrete problem: AI agents currently proceed with tasks even when they should recognize they don't have enough reliable information to do so.
• The system grades models on how well they judge their own uncertainty, rather than only measuring whether their final answers are correct.
