Intervention(s)
We conduct three experimental surveys.
In Survey A, respondents are randomly assigned to one of two main treatment groups or a control group, designed to assess the impact of emotions on policy attitudes:
Positive emotion treatment branch: Respondents watch two one-minute relaxation videos (before the trade and wealth \& taxation blocks) designed to induce calm, and the open-ended policy questions in each policy block are framed in a positive way, prompting optimism. The first video features serene landscapes—green fields, a lake, an eagle in flight, a cyclist by the water, lavender fields, and snow-capped mountains—accompanied by peaceful music. The second video showcases tranquil mountain scenery, a blue sky, a flowing river, and a lush green forest from above, also with peaceful music.
Negative emotion treatment branch: Respondents watch two one-minute anger-inducing videos (before the trade and wealth \& taxation blocks) designed to evoke anger, and the open-ended policy questions in each policy block are framed negatively, further prompting anger. The first video is a one-minute video highlighting government corruption and corporate greed as causes of worsening disasters. It focuses on a wildfire ignited by PG\&E’s failure to replace aging electrical line hooks, which resulted in 84 corporate homicide charges, showing the victims and the destruction caused. The second video is a one-minute video highlighting government favoritism toward corporations and the lack of real accountability. It details how PG&E, despite making \$17 billion annually, faced only a \$3.5 million fine—the maximum penalty under California law—for the wildfire caused by its negligence. The video also exposes how the California Public Utility Commission refused to assist in prosecuting PG\&E, withholding evidence that could have strengthened the case against the company.
Control branch: The open-ended policy questions at the beginning of each policy block are framed in a neutral way.
To be able to disentangle the effect of the video from the effect of the framed question, we also added two secondary treatment groups:
Effect of the framed question only: The open-ended policy questions at the beginning of each policy block are framed in a negative way, prompting anger.
Effect of the video only: Respondents watch the same two relaxation videos and the open-ended policy questions are framed neutrally.
In Survey B, respondents are randomly assigned to one of three main treatment groups or a control group, designed to dig further the impact of negative emotions distinguishing fear from anger.
Anger treatment branch: Respondents watch the same two one-minute anger-inducing videos as in Survey A.
Fear treatment branch: Respondents watch two one-minute fear-inducing.
Positive emotion treatment branch: Respondents watch the same two one-minute relaxation videos as in Survey A but are not asked the positively framed open-ended question.
In Survey C, respondents are randomly shown a Tweet with an emotional tone (anger, fear or positive) on a specific policy topic and are asked whether they'd like to retweet it.
