The Science of Recognition: How Repetition Shapes Consumer Choice

The power of the mere exposure effect becomes clearer when examining how brands use repetition.

Marketing researcher Herbert Krugman argued in the 1970s that advertising often influences consumers even when they pay little conscious attention. According to Krugman, repeated exposure can gradually shape familiarity and recognition without requiring deep processing of the message.

Later research strengthened this view. In a 1992 review published in Current Directions in Psychological Science, Robert Zajonc revisited decades of evidence and concluded that preferences frequently emerge before conscious reasoning. People may develop positive feelings toward an object before forming a detailed explanation for those feelings.

This dynamic can be observed across modern advertising. Consumers encounter logos on billboards, social media feeds, sports jerseys, video sponsorships, and streaming platforms. Any single exposure may seem insignificant. Collectively, however, they create familiarity.

Importantly, marketers do not always expect immediate purchases from these encounters. The objective is often to ensure that when a buying decision eventually occurs, the brand already occupies a familiar place in memory.

The result is a subtle shift in competition. Brands are not merely competing for attention in the present moment. They are competing to become familiar enough that future choices feel easier.
