SIGNAL INDEX

An index of what matters and why

Signal Index is an independent publication that follows credible evidence to identify the changes in science and technology beginning to shape the future.

Why Signal Index Exists

The problem is not a lack of information. Valuable research and technological advances emerge every day across different disciplines, organisations and countries. The challenge is seeing how these developments connect and what larger changes may be taking shape while they are still emerging.

Signal Index was created to help address that challenge. Rather than reporting technology news, it follows credible evidence over time to understand how important changes develop, spread and eventually become part of the wider world.
