The application of assertive language in environmental persuasion has produced mixed results. Besides the language content intensity such as assertiveness, this research proposes that a congruency of language content and visual presentation format such as typeface could be achieved to increase message persuasiveness of pro-environmental behaviors in the tourism domain. With three scenario-based experiments focusing on a garbage sorting initiative at a tourist attraction, a food waste reduction program in a restaurant, and an animal protection donation advocacy in a national park, respectively, the research demonstrated that matching assertive language with machine-written typeface, or non-assertive language with handwritten format, could enhance tourists’ compliance behaviors. The research also uncovered perceived fit and a subjective experience of feeling right as the underlying mechanism, and tourist involvement as a boundary condition for such a congruency effect. The theoretical and practical implications are also discussed.
