““The child has learned to predict the dog’s behavior and no longer finds the pup quite as entertaining. By now, the child’s mind is occupied with dump trucks, fire engines, bicycles, and new toys that stimulate the senses — until they too become predictable. Without variability, we are like children in that once we figure out what will happen next, we become less excited by the experience. The same rules that apply to puppies also apply to products. To hold our attention, products must have an ongoing degree of novelty.””
