I only read the synopsis of the Wikipedia article and am not very versed in this particular model. However to me, the notion doesn't seem to make sense. If you're talking about philosophical zombies, you're acknowledging that consciousness is a real phenomenon, of some sort. If we're sitting here typing about it, we should also conclude that it has an effect on the physical world. So a philosophical zombie, being physically identical to a human but for not having a consciousness, would act differently than a human because it lacks consciousness, which is a real phenomenon with implications on the physical world. (which I suppose you allude to in your second paragraph) EDIT: Ok I think I see a counterargument. Perhaps belief in consciousness is purely physical, and actual consciousness is just perception of this belief, and a perception of choice in acting on it, whereas our actions are deterministic. Seems like a strange scheme, but I suppose it's possible.
