"But despite the fact that innovative cultures are desirable and that most leaders claim to understand what they entail, they are hard to create and sustain. This is puzzling."

I really don't see how this is puzzling.. there's plenty of people living in denial, sure, but there's whole a load of people who understand intellectualy how to do all kind of things: lead a happy fulfilling life, bring up your kids in a healthy way, be physically healthy. Knowing things is really overrated.
