“I think that’s what bothers designers about poorly made products. Not only does bad design seem lazy and inattentive, we wonder if there could be another explanation for its shoddiness. If an interface is confusing, was it made that way intentionally or are the designers just incompetent? And if I learn that a product is out of stock only after I decide to buy it, am I the victim of an honest mistake or is the merchant pulling a bait-and-switch on me?”
