Technology may make comparisons easier in the future. Digital shelf labels and online product databases can display standardized unit prices automatically. Shopping applications may allow consumers to compare historical prices and quantities. Retail systems can also present different package sizes in consistent units. These tools reduce the mental arithmetic required from shoppers.
Still,
no technological solution completely removes the influence of appearance. People respond rapidly to visual information because that is how human perception works. A large or unusually shaped container will continue to communicate an immediate impression before someone reads the numbers. The goal is therefore not to eliminate visual design but to supplement it with clear and accessible factual information.
