Showing environmental harm first heightened attention to the green solution that followed
Researchers at Pusan National University and Breda ran the same negative-to-positive message order through a 64-channel EEG session and a behavioural study. Arousal moved attention, valence moved intention.

What happened
- Insin Kim and Alisa Kazakova of Pusan National University worked with Marcel Bastiaansen of Breda University of Applied Sciences and Tilburg University on how emotion unfolds across stages of green persuasion.
- In the first study, a 64-channel EEG experiment found that prior exposure to tourism-related environmental degradation heightened early attention and sustained neural engagement with green solutions shown afterward.
- In the second study, the same negative-to-positive order produced a contrast-based positive shift in emotional valence, and that shift increased participants' intention to engage in pro-environmental behaviour.
- Arousal helped early attention and message processing without directly influencing intention, while valence-based evaluation was the factor associated with later judgment and behavioural intention.
- The authors add that environmental information should be authentic and proportionate, not built to frighten or overwhelm visitors, and the paper appeared in the Journal of Travel & Tourism Marketing.

Why it matters
- decision Message order becomes something a communications team sets deliberately. The version worth running is harm-then-solution against solution-alone with an observed uptake rate, because the reported outcome was stated intention.
- constraint Engagement dashboards mostly track the arousal end of this chain, so a campaign tuned to dwell and attention metrics is optimising the link that stopped short of intention here.
- precedent The authors extend the sequencing logic to climate, conservation and public health communication. Using it there borrows a result obtained with tourism materials and tourism-framed harms.
Environmental campaigns usually deliver the problem and the solution as separate messages [13]. The framework these researchers built treats them as one sequence, and in their account arousal moved attention while valence moved intention [6]. Contrast is the proposed reason the order pays off: a solution read immediately after a harm message is evaluated against that harm. In the second study, that comparison pushed emotional valence in a positive direction, and that shift raised intention to act [5].
The two studies were designed to measure different links in that chain, one with neural and one with behavioural evidence [9]. A 64-channel recording is a timing instrument. It shows when attention is allocated to the solution message and how long engagement lasts. That is what Study 1 reported: heightened early attention and sustained neural engagement with green solutions shown after the degradation message [4]. It cannot show what a visitor does at a checkout page. Study 2 measured the valence-to-intention path, and stated intention is the outcome it reported [5].
The phys.org account does not report sample sizes, effect sizes, or which message orders were compared against each other. The size of any advantage from the negative-to-positive sequence cannot be worked out from it [14].
Kim said: "Our findings clarify the distinct functional roles of arousal and valence across successive stages of persuasion: early emotional activation facilitates attention and message processing, whereas subsequent valence-based evaluation drives later judgment and intention formation" [7].
The team cautions that environmental information should be authentic and proportionate, not designed to frighten or overwhelm visitors [8]. The solution has to be credible and achievable, such as a lower-carbon travel option or a contribution to protecting a destination [15]. The researchers suggest a designed progression from environmental concern to a feasible solution can translate heightened attention into engagement [16]. Airlines, cruise operators and nature-based destinations are the organisations they name as candidates, across booking platforms, destination apps and smart signage [10][11].
I would treat harm-then-solution as a hypothesis with a reasonable psychological account behind it, tested so far on attention and self-report. The field version is cheap: the same two messages in two orders on a live booking page, with the opt-in rate as the outcome rather than a questionnaire item.
What to watch
- The full Journal of Travel & Tourism Marketing paper, for participant numbers, effect sizes, and whether a reversed or solution-only order was run as a control.
- Any field test that puts the two orders on a live booking flow and reports opt-in or donation rates instead of stated intention.
- Whether the attention gain survives repeat exposure, since travellers meeting the same harm-then-solution sequence at several stages of a trip are not naive to it.
