Aaron Weyenberg eloquently explains:
I don’t call myself a UX Designer for one simple reason: I don’t believe experiences can be designed. At least not outside the realm of science fiction or without knowledge about ourselves that we have yet to discover. I view User Experience as a field of study with a range of disciplines within it, not something we author (particularly not by a single designer). Products are designed. Experiences are their resultants.
I wholeheartedly agree. User experience is affected by the product, the user and the context in which the interaction occurs; of the three, only products can be designed, while users and contexts can be predicted at best.
