The Ingenuity Gap is a non-fiction book by Canadian academic Thomas Homer-Dixon. It was written over the course of eight years from 1992 to 2000 when it was published by Knopf. The book argues that the nature of problems faced by our society are becoming more complex and that our ability to implement solutions is not keeping pace. Homer-Dixon focuses upon complexities, unexpected non-linear results, and emergent properties. He takes an inter-disciplinary approach connecting political science with sociology, economics, history, and ecology.
