Does prompting people to volunteer for the climate spur or hamper further environmental engagement? We address this question in an online experiment with 10,670 German respondents. First, respondents read a text explaining how to help scientists fight climate change. Second, participants choose whether to do a real-effort task, like the behavior emphasized in the text. Third, respondents can sign a petition against climate change. In Study 1, we manipulate the narrative of the texts. We compare narratives condemning inaction or praising climate action against a neutral narrative (control) and an unrelated article (placebo). In Study 2, we investigate how the difficulty of the first behavior moderates behavioral spillovers. In Study 3, we test if the similarity between the domains of the two behaviors (e.g., environment, health) moderates spillover effects. None of our narratives increase the uptake of the real-effort task. Doing the real-effort task does not increase the likelihood of signing the petition either. Difficulty and domain-similarity do not moderate these effects.Protocol registration The stage 1 protocol for this Registered Report was accepted in principle on January 1, 2023.

促使人们自愿参与气候行动会促进还是阻碍进一步的环境参与？我们在一项针对 10670 名德国受访者的在线实验中探讨了这个问题。首先，受访者阅读一篇解释如何帮助科学家应对气候变化的文本。其次，参与者选择是否完成一项实际任务，例如文本中强调的行为。第三，受访者可以签署一份反对气候变化的请愿书。在研究 1 中，我们操纵了文本的叙述方式。我们将谴责不作为或赞扬气候行动的叙述与中性叙述（对照）和无关文章（安慰剂）进行了比较。在研究 2 中，我们调查了第一个行为的难度如何调节行为溢出。在研究 3 中，我们测试了两个行为领域之间的相似性（例如，环境、健康）是否调节溢出效应。我们的叙述都没有增加实际任务的完成率。完成实际任务也不会增加签署请愿书的可能性。难度和领域相似性都不会调节这些影响。 方案注册 本注册报告的第 1 阶段方案于 2023 年 1 月 1 日原则上被接受。该方案在被期刊接受后可在以下网址找到：https://doi.org/10.17605/OSF.IO/JPT8G 。
