From an HBR interview with Peter Scoblic:

One of the conclusions that I’ve come to in my research is that imagination is a woefully undervalued strategic resource. And that what organizations can benefit from tremendously is the institutionalization of imagination.

1. If imagination is "woefully undervalued" then organizations are not hiring for it.

2. It is likely, then, that imagination is going to be in rather short supply -- no matter how much the organization needs it or wants it.
