Your metaphor is not clear to me, but you seem to be asserting more of an empirical problem with people, not saying anything about the heuristic itself. It does not speak to how we know a system does what it does, or that we can even know I guess, so even if you have some kind of point here I don't see how it applies in this case.

"If we know what a system does, we know that it is its purpose": is that ok?
