The answer to the paradox, I think, is that you have to design for the user, but you have to design what the user needs, not simply what he says he wants. It’s much like being a doctor. You can’t just treat a patient’s symptoms. When a patient tells you his symptoms, you have to figure out what’s actually wrong with him, and treat that.

– Paul Graham
