Before
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.
