What is the result of the mere exposure effect on people’s preferences?

The mere exposure effect is a psychological phenomenon where individuals tend to develop a preference for things merely because they are familiar with them. This effect suggests that repeated exposure to a stimulus can lead to an increase in affinity or fondness towards that stimulus. Therefore, when individuals encounter familiar items—whether they are voices, faces, or products—this prior exposure can evoke positive feelings and make them seem more appealing or attractive.

In practical terms, frequent exposure diminishes the uncertainty or anxiety associated with unfamiliar items, fostering a sense of comfort and preference for what is known. This explanation aligns perfectly with the outcome associated with the mere exposure effect, confirming an increased fondness for familiar stimuli.
