Why Unhappy Customers Are Unlikely to Share Their Opinions with Brands

For brands to thrive, they must understand consumer sentiment; if consumers’ likelihood of sharing their opinion is a function of their attitude toward a brand, then brands’ perception of consumer sentiment may be systematically biased. While research in consumer-to-consumer sharing (i.e., word of mouth) suggests that those with extreme attitude are more likely to share than those with neutral attitude (a U-shaped relationship), the relationship between consumers’ attitude toward a brand and their propensity to share with a brand is unknown. In contrast to the U-shaped pattern observed in word of mouth, the authors find a hockey stick–shaped relationship between attitude and sharing with brands (“__/”). Those with positive attitude (vs. neutral attitude) are more likely to share their opinion, but those with negative attitude do not show a similar increase in sharing. The authors show that this pattern emerges because, among consumers with positive (vs. neutral) attitude toward a brand, reciprocity norms drive increased sharing, but among consumers with negative (vs. neutral) attitude, competing mechanisms drive behavior: the desire to vent increases sharing, but at the same time an aversion to criticize others directly deters sharing. The authors test these ideas using a series of studies, including a field study.
