Promotional phrases as analogical questions: inferential fluency and persuasion

Purpose As an alternative to straight rhetorical questions, questions using analogies that invite the reader to think about the frame of reference to answer the target have been used in advertising to persuade. This paper aims to investigate consumer responses to the use of analogical questions in ads for incrementally new products and the important variables moderating those responses. Design/methodology/approach Four between-subjects experiments examined how product evaluations in response to analogical questions differ from non-analogical variants as a function of consumers’ persuasion awareness (Studies 1 and 2) and also tested if the effectiveness of an analogical question among potential consumers who are more aware of persuasion attempts might be enhanced only when it is proposed with a strong rather than a weak frame of reference (Study 3), and when the frame of reference and the target share underlying similarities (Study 4). Findings Analogical questions are more persuasive than non-analogical variants for participants who are more aware of persuasion attempts. Inferential fluency mediates the results. Furthermore, the positive impact of analogical questions for participants high in persuasion awareness is diminished when the frame of reference is weak or from a dissimilar domain. The same patterns are not evident for participants who are less aware of persuasion attempts. Research limitations/implications Drawing on the concepts of inferential fluency, this study offers an empirically-based view of how the analogical questions in advertising may bias the responses exhibited by individuals who demonstrate either a high or low level of persuasion awareness. Practical implications The inclusion of an analogy can lower consumers’ tendency to behave in a defensive manner by facilitating inferences about intended claims that are implicitly stated in a rhetorical question and achieve higher levels of persuasion. Originality/value This study contributes to prior study on rhetorical questions within a persuasion communication by adopting inferential fluency as an underlying mechanism for analyzing the impact of analogical questions and individual’s awareness of persuasion.
