Why

The AI developed biases from its pre-training on the standard model (ΛCDM), leading to "negative transfer" where it struggled to distinguish between different physical effects and missed potential new physics.

How this affects you

This research highlights that while AI can accelerate scientific discovery, careful oversight by human experts is crucial to prevent pre-training biases from misleading investigations into unknown phenomena, particularly in complex fields like cosmology.
