Actually calling this a theory is giving it too much credit as there is no experiment that can be performed to prove it wrong, or even a experiment that would allow you to learn a little more about it.

You *could* show that, for if the consciousness were changed but not the behaviour, that would lead to absurdity. It would mean that you could go blind but not notice you were blind and behave as if you had normal vision, or you could go blind but stand by helplessly while your body behaved normally and declared that everything looked normal.
> That's why consciousness theories, as opposed to intelligence theories, are so popular on the internet, they're easy because they don't have to actually do anything or explain any experimental results, they can just prattle on and on and one consciousness theory works just as well (or badly) as another. It would take intelligence and a lot of it to come up with a good intelligence theory; but a consciousness theoretician doesn't need that, intelligence is just optional for him. Consciousness is easy but intelligence is hard.
