Experimental Design (Public) In this experiment, we will prime participants to think about negative events in the future. The priming will be induced by having participants answer questions about a negative future. In the control condition, participants will answer questions unrelated to this context. After randomly manipulating context salience and a short manipulation check (word stem completion task), we will elicit subjects’ pro-environmental behavior using a new incentivized decision task in which participants can decide between keeping money or investing money in an environmental project. Thus, this task consists of a decision tradeoff between own financial and environmental rewards. After the incentivized decision task, participants will complete a series of self-report scales on pro-environmental behavioral intentions, pro-environmental behavior, pro-sociality, future orientation and answer demographic questions. If we identify a statistically significant priming effect, we will ask the same subjects to participate in the incentivized environmental decision task one week after the manipulation in order to examine whether priming is still effective.

Planned Number of Clusters The number of participants planned for the experiment is 540 people completing the study. We advertise for 600 participants to take into account individuals excluded due to the restrictions below. We will exclude subjects that: - do not complete the MTurk task within 60 minutes of starting; - exit and then re-enter the task as a new subject (as these individuals might see multiple treatments); - are not approved for any other reason (e.g. not having a valid MTurk ID); - do not answer the open questions as requested (e.g. wrote a few words when we asked for at least 2 sentences) - give unusual comments to the open questions (e.g., irrelevant words, copied and pasted text from Google) - failed crucial attention checks In addition, and in line with previous research, we will analyze the data once with those who do not believe in climate change and once without them. Based on previous research, we expect to exclude about 10-15 percent of participants because they did not meet the restrictions above.
