A new research paper explores issues with how action effects are tested in AI world models, drawing parallels to biological experiments. The authors identify two primary problems: future actions can be mistaken for historical data, and pooled scores can obscure small model errors. They propose a tempered statistic as a more valid diagnostic, demonstrating its effectiveness on diffusion models, Atari games, and control tasks, significantly outperforming standard pooled tests.
