Experimental Design

Experimental Design
We vary the perceived social pressure associated with making a Tweet about a socially sensitive topic.
Experimental Design Details
Participants are shown an article written by Princeton criminologist Patrick Sharkey discussing the likely effect of defunding the police on violent crime and decide whether or not to (privately) join a campaign to oppose defunding the police. They are then told they will have the opportunity to schedule a post to be made on their Twitter account encouraging their followers to sign a petition to oppose defunding the police. The experiment manipulates only one word: whether the post indicates that the participant saw the article before joining the campaign, or after joining the campaign. (They are told that this post will be made public if and when we have reached survey respondents in all US counties. However, given that we are collecting fewer observations than the number of US counties, this will not happen, and thus the posts will never be made public.)

The experiment manipulates only one word: whether the post indicates that the participant saw the video before joining the campaign, or after joining the campaign. We are interested in examining whether respondents who believe that their audience will believe that they saw the video before joining -- and thus, had an "excuse" to join -- are more willing to schedule the post.

Experiment Characteristics

Sample size: planned number of clusters
NA
Sample size: planned number of observations
We will ideally recruit 1000 participants. However, based on conversations with our survey provider, it may be infeasible to recruit 1000; they have guaranteed that we can recruit at least 500. Thus, we will end our collection when we reach 1000 or after seven days have elapsed (whichever occurs first). We will restrict our sample to people who pass a simple attention check (pre-intervention).
Sample size (or number of clusters) by treatment arms
250-500 treatment, 250-500 active control (see above)
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
With 500 respondents total, based on our pilot data, we will have 80% power to detect an 11 percentage point effect at the 10% level. With 1000 respondents, we will have 80% power to detect a 8 percentage point effect at the 10% level.
