Can Heuristic Cues Improve Voluntary Carbon Offsetting Message Effectiveness?
研究通过全国性调查和心理生理实验，发现首因-近因、锚定和登门槛等启发式线索能提高航空旅客的自愿碳抵消意愿，但透明度和统计信息更能吸引注意力。
Encouraging air travelers’ participation in voluntary carbon offsetting (VCO) remains challenging. Drawing on dual-process and social influence theories, this study investigates whether heuristic cues can optimize message design for online carbon offsetting. Through sequentially designed randomized national surveys and psychophysiological experiments, results revealed that messages leveraging primacy-recency, anchoring , and foot-in-the-door techniques are most effective in increasing carbon offsetting intentions. Findings indicated that women tend to be rational carbon offset purchasers while older men are more likely to be heuristic-induced purchasers. The experimental study further reveals that transparency and efficacy messages with statistical information, rather than heuristic cues, are the most effective approaches in raising respondents’ attention to carbon offsetting details. Practical communication strategies such as providing readable and accurate information are proposed to promote participation in aviation VCO programs.
