Objectivity tends to be one of the core values of technical fields. The fundamental laws of physics dictate the properties of microprocessors, and chemistry defines the properties of the materials we use. These methods make up the API, determining how that application behaves and what it is capable of doing. The way that people interact with technology, however, is anything but objective. They bring a lifetime’s worth of experiences that guide their behavior and frame their expectations for both what the technology will do for them and how it will perform its duty.
