Global Workspace Theory (GWT)

This introduces Global Workspace Theory (GWT) — a theory from cognitive science that inspired the series' framing. It describes a small shared workspace that broadcasts information to the whole brain.

How it works

1. 1In humans, specialist systems (vision, hearing, memory, movement, emotion) run unconsciously.
2. 2Information that reaches the global workspace becomes consciously accessible.
3. 3Many systems (language, planning, reasoning, action) can then read and use it.
4. 4Analogy: a library holds all knowledge, but only a few books sit on the 'conscious desk' at once.
5. 5The desk is the global workspace everyone can read from.

Key points

• Key properties: broadcasting to many systems, limited capacity, flexible use, reportable.
• It's the basis of deliberate thought.
• The series maps this idea onto a model's internal workspace.
• GWT is where information becomes broadly available across the mind.

Why it matters

GWT gives a useful metaphor for interpretability: a shared, limited workspace that broadcasts key information — helping explain how a model might coordinate reasoning internally.

Frequently asked questions

What is the global workspace?

A small, shared space where information becomes broadly accessible to many cognitive systems at once.

Why use it as an analogy?

It captures the idea of a limited, broadcast 'thinking space' that coordinates reasoning.
