改变与气候变化有关的态度和行为是困难的。提供信息、呼吁价值观和规范或制定政策的努力成效有限。在这里，我们研究参与气候预测市场是否可以改变态度，让市场作为一个无党派的裁决者，并促使参与者把他们的“钱在他们的嘴”。在两项实地研究中，我们表明，对气候事件的押注改变了：（1）参与者对气候变化的关注，（2）对补救气候行动的支持和（3）对气候问题的了解。虽然在研究1中，这些影响取决于参与者的投注表现，但在研究2中，它们与投注结果无关。总的来说，我们的研究结果表明，气候预测市场可以为改变人们与气候相关的态度和行为提供一条有希望的道路。
Modifying attitudes and behaviours related to climate change is difficult. Attempts to offer information, appeal to values and norms or enact policies have shown limited success. Here we examine whether participation in a climate prediction market can shift attitudes by having the market act as a non-partisan adjudicator and by prompting participants to put their ‘money where their mouth is’. Across two field studies, we show that betting on climate events alters: (1) participants’ concern about climate change, (2) support for remedial climate action and (3) knowledge about climate issues. While the effects were dependent on participants’ betting performance in Study 1, they were independent of betting outcomes in Study 2. Overall, our findings suggest that climate prediction markets could offer a promising path to changing people’s climate-related attitudes and behaviour.
