Interesting. Now that you put it that way... it does make it really difficult to see where exactly the difference is. Even if it is in the process, it isn't easy to point out since if I encounter something new (that I don't have valued before) I would think through the pros and the cons (if I was smart). And if a thinker encounters a familiar situation (which he has valued before) he will use the old formula (if he is efficient). So, where is the difference?
