From Destination to Daily Life: A Longitudinal Study on the Effects of Flashback Nudging on Pro-environmental Behavior Spillover

This study examines how flashback nudging—a reminder of past pro-environmental actions—delivered through a chatbot survey over 6 weeks in a quasi-experimental design, can facilitate pro-environmental behavior spillover among tourists visiting nature-based destinations. Integrating conversational artificial intelligence allows for personalized, timely, and scalable interventions, making the delivery of flashback nudges more efficient and engaging than traditional methods. Flashback nudging effectively strengthens the impact of environmental self-identity on behavioral change. Although nudges take time to work, the multigroup analysis revealed significant differences in self-reported past pro-environmental behaviors between the treatment and control groups. The findings demonstrate the importance of deliberate, technology-enabled interventions in enhancing meaning-making processes and promoting transformative tourism experiences. Artificial intelligence advances behavior change efforts by enabling innovative, lasting environmental engagement. This study emphasizes the potential of conversational artificial intelligence to drive tourism’s contributions to a sustainable future, advancing the discourse on leveraging technology for behavioral interventions in tourism.
