I don't use the term "intuition" in the exact way I use the term "intuitive" wrt a UI. I warrant that you're correct that my thought processes could align to some extent with those of the creators of any interface that I'm attempting to grok and that this appears as if the interface is intuitive.
Intuitiveness (rather than "intuition" to make the distinction I hinted about above) in an interface that relies on metaphor (affordance of buttons enhanced by shadow, etc.) is simply about familiarity.
A previous comment mentioned a simple light-switch as being possibly lacking in affordance for a jungle-dweller who lacks knowledge of our technology. I'd agree that they're unlikely to intuit what to do, but the interface to my mind is intuitive in that once one tries it then the feedback leads to a ready analysis of the effect and enables rapid understanding of the superficial workings.
What's intuitive? It's all learned from something. We can't even pick our nose when we're first born, we have to figure out how to move our arm.
There indeed is a real intuitive.
