on visual shortcuts that allow them to make decisions quickly. A familiar package may be recognized by its logo, shape, or color without the shopper rereading every measurement printed on it. This process is efficient and usually makes everyday shopping easier. However, it can also create confusion when a familiar product changes in size, quantity, or formulation while retaining much of its previous visual appearance. The shopper may recognize the package faster than they notice the changed net quantity statement.
This tendency is not unusual or irrational. Human perception constantly uses shortcuts to interpret complicated environments. In a supermarket containing thousands of products, comparing every item mathematically would require enormous amounts of time and concentration. People therefore use previous experience, visual familiarity, perceived size, price, and brand recognition to narrow their choices. These shortcuts can be extremely useful. They can also make packaging design unusually influential.
