Abstract: | Marketers often use numerical comparisons in promotional claims to signal superior product offerings. A potentially misleading practice involves omitting the reference point deliberately in order to make the focal claim more appealing—a persuasion tactic referred to as “baseline omission” in the present research. In two experiments, this research demonstrates that consumers tend to perceive this tactic as more effective on others than on themselves. The self‐others difference is more salient among consumers with more persuasion knowledge. Consumers’ concerns about its effectiveness on themselves, rather than on others, better predict their supportiveness to regulate the use of baseline omission. |
