Five stages to innovation. People: 

1. Deny that the innovation is required. 

2. Deny the innovation is effective. 

3. Deny the innovation is important. 

4. Deny the innovation will justify the effort required to adopt it. 

5. Accept & adopt the innovation, enjoy its benefits, attribute it to people other than the innovator, and deny the existence of stages 1-4.

- Inspired by Alexander von Humboldt’s three stages of scientific discovery,  as referenced by Bill Bryson in his book, A Short History Of Nearly Everything.
