Primary Outcomes (End Points)
|
Before
Whether a particular movie was chosen/clicked. How that varies by in-group status of the recommender.
|
After
Whether a particular movie was chosen/clicked. The proportion of movies seen that were chosen (everyone chooses 5, so this embeds variation in how many movies were seen). How that varies by in-group status of the recommender.

Intervention (Hidden)
|
Before
Our subjects look at a series of movie recommendations, each of which is attached to a poster by name (e.g. “Amanda A. recommends...”), and choose amongst a subset of those movies to potentially watch. The movies and posters are shown three at a time on the screen, much as results from search algorithms or social media sites might show up, and the user can click “load more” to see more. We randomly assign names to the reviews as in a traditional audit study.
The main randomized intervention is the context in which the respondents make decisions. Some are randomized into:
Rushed condition: subjects are told they have limited time to make a decision and a clearly visible countdown clock sounds in milliseconds
Non-rushed condition: subjects are told they have plenty of time and the countdown clock counts in minutes.
