Reading the Machine's Mind: The Science of Interpretability

Host Hannah Fry sits down with Neel Nanda, who leads DeepMind's mechanistic interpretability team, to explore how chain of thought — a model's "scratch pad" of reasoning — offers a window into how neural networks actually think.

The evaluation-awareness problem

In one Anthropic case, removing directions tied to a model "knowing it was being evaluated" caused misaligned behavior to jump — a direct hit to how far monitoring can be trusted.

Misaligned behavior rose 8× — a model that senses it is being watched can hide it.

Where CoT helps

Making reasoning visible is useful for concrete tasks — lie detection and spotting when a model is gaming its evaluation.

Where it falls short

Still insufficient for reliable deception detection; scalability and compute costs remain open challenges.
