Explain how habitual decision making works.

Habitual problem solving involves decisions that are made with little or no conscious effort. Many purchase decisions are so routine that we may not realize we've made them until we look in our shopping carts. Choices characterized by automaticity are performed with minimal effort and without conscious control. Although this kind of thoughtless activity may seem dangerous or, at best, stupid, it is actually an efficient way to operate. The development of habitual, repetitive behaviour allows consumers to minimize the time and energy spent on mundane purchase decisions.
