We will discuss a cognitive preference that can impact our decision-making. The mere-exposure effect, also known as the familiarity principle, is the human tendency to prefer what is familiar to us and to make us allergic to changes. As per the Encyclopedia of Social Psychology, it is “a phenomenon that simply encountering a stimulus repeatedly somehow makes one like it more”.
One direct application of this effect is in the area of advertisements. Marketing people have used this technique to perfection for brands and products through repeated campaigns to encourage customers towards them.
