A recent study has shown that the order in which sustainability messages are delivered can significantly affect how people respond to them. Researchers found that the emotional reaction to an initial message can shape how later messages about environmental issues are understood. This is especially important in the tourism industry, where visitors are often encouraged to make eco-friendly choices. The study was led by Professor Insin Kim and Dr. Alisa Kazakova from Pusan National University, with contributions from Dr. Marcel Bastiaansen from Breda University of Applied Sciences and Tilburg University in the Netherlands. They explored how emotions change as people are exposed to different messages about sustainability. The researchers created a framework that breaks down the emotional processing of these messages into stages, focusing on how people react emotionally and how that affects their understanding. In the first part of the study, participants wore a 64-channel electroencephalography (EEG) cap to measure brain activity. The results showed that when people first saw images of environmental damage, they were more attentive and engaged when later shown solutions to these problems. In the second part, the same pattern of negative-to-positive messaging led to a more positive emotional response and a stronger desire to act in an environmentally friendly way. The study found that emotional arousal—like surprise or excitement—helps people pay attention to messages early on, but it doesn't directly lead to action. Instead, the emotional tone or valence of the message—whether it feels positive or negative—plays a bigger role in shaping people’s decisions later on. This means that while shocking images might grab attention, a more positive and hopeful message is more likely to encourage people to take action. The researchers suggest that tourism businesses could use this insight to design more effective sustainability campaigns. Instead of presenting environmental issues and solutions separately, they recommend creating an emotional journey that starts with highlighting a problem and then moves to a positive, achievable solution. For example, a campaign might first show the impact of plastic waste on oceans, then suggest simple ways visitors can reduce their plastic use. The study also emphasizes the importance of authenticity in these messages. Information should be accurate and balanced, not just designed to scare people. By connecting emotionally powerful environmental messages with clear, feasible solutions, organizations can encourage more meaningful engagement with sustainability efforts. This approach could soon influence how messages are presented on travel booking websites, mobile apps, and even in immersive experiences like virtual reality tours. The principles from this study could extend beyond tourism to other areas like public health, conservation, and climate action. The key takeaway is that successful communication isn’t just about creating strong emotions, but about guiding people’s attention toward positive, credible solutions that encourage responsible behavior. As Kim notes, future campaigns should focus on helping people feel motivated to act, not just shocked by the problem.
