Integrated Information Theory:
Consciousness and Intrinsic Ontology

Welcome to the IIT Wiki

Integrated information theory (IIT) aims to provide a rigorous, scientific account of consciousness and its place in nature. This Wiki is designed to support you in learning about the IIT methodology, its mathematical formalism, and the intrinsic ontology that follows from the theory. IIT has been largely developed at UW–Madison's Center for Sleep & Consciousness, which is also responsible for the content in this Wiki.

How to use this Wiki

If you are new to IIT, we suggest you follow the sequence of pages in the menu. To ease the learning process, we have interlinked the Wiki pages with one another, with a glossary, and with academic IIT papers.

Like the theory itself, this Wiki is a work in progress, and we invite you to help us improve and expand it. At the bottom of every page, you'll find a comments area, where you can ask questions or upvote existing questions

If you'd like to hear when new FAQs or resources are posted to the Wiki, sign up for our newsletter on the right.

Acknowledgments

The current version of the IIT Wiki was created primarily by Jeremiah Hendren, Matteo Grasso, and Bjørn Erik Juel, in close consultation with Giulio Tononi. The content builds especially on Tononi's book On Being (forthcoming) and the many theoretical and empirical IIT papers written by researchers at the UW–Madison Center for Sleep and Consciousness over the last two decades.

The IIT Wiki was made possible in part through the support of the Templeton World Charity Foundation. IIT research more generally has been supported by the Templeton World Charity Foundation, the Distinguidhed Chair in Consciousness Science at UW–Madison, the David P. White Chair in Sleep Medicine at UW–Madison, the Tiny Blue Dot Foundation, the National Institutes of Health, the Natural Science and Engineering Research Council of Canada, the Paul G. Allen Family Foundation, and the McDonnell Foundation, among others.
