That may be a valid idea, maybe Pavlina really does all this just for the money. But people would argue, that his ideas are still beneficial and therefore it doesn't matter how the true reality looks like. Sort of like the behavorist's black box...

What do you have to say about this? You have to admit that this is how most theories work. You make them up, look if they can explain what is happening and if they do we keep them. They may be wrong, but at least they are serving as the basis for hypothesizing, predicting outcomes etc. Like Freud's psycho dynamic theory, or Einstein's theory etc. The int-man model may be correct or not but people argue that it's a good model of our world, and using it we can predict events, cause events happening etc.
