Out of everything happening in your brain right now, only a tiny fraction is consciously accessible — thoughts you can describe, hold in mind, and reason with.

Anthropic found a strikingly similar divide inside their AI model, Claude.

Their experiments were inspired by a leading theory in neuroscience: the global workspace theory. It holds that a thought becomes consciously accessible when it enters a shared “workspace” that’s broadcast across the brain.

They found a set of representations in Claude’s neural activity that play a similar role.
