Abstract
There is growing evidence that people seek to avoid contact or exchange of information with others that have different views than theirs. In this study, we test whether raising people’s awareness about the fact that they share views on fundamental values (human rights) increases the willingness to listen to others who share different political views.

Experimental Details

Interventions

Intervention(s)
Main study participants (i.e., a representative sample of Americans) will be asked to choose whether they would like to listen to individuals expressing their (different) views on political issues. Participants are randomized into one of the control or two treatment groups; the treatment groups differ by the information shown prior to listening to others.
Intervention Start Date
2021-08-23
Intervention End Date
2021-09-13

Primary Outcomes

Primary Outcomes (end points)
Willingness to engage and level of engagement, measured as number of times a respondent was willing to listen to others and the length of time they actually spent listening to others.
Primary Outcomes (explanation)
The primary outcome measures will be automatically recorded.

Secondary Outcomes

Secondary Outcomes (end points)
Change of views and firmness of views.
Secondary Outcomes (explanation)
Secondary outcomes will include individuals' firmness of views before and after treatment as measured by 1-to-10 survey scale questions.

Experimental Design

Experimental Design
This multi-phase study will study individuals' willingness to listen to people with different views on important political topics. Interventions will consist in randomly assigned information about others that can potentially increase individuals' willingness to engage with peers who hold different views on the selected topics. The study will take place in the U.S. and the main study phase will include a representative sample of Americans.
Experimental Design Details
Not available
Randomization Method
Randomization is done by a software.
Randomization Unit
The unit of randomization of the individual (i.e. the survey respondent).
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
The main experiment will include approximately 2,500 respondents randomly allocated across one control and two treatment groups. Participants will not be clustered.
Sample size: planned number of observations
For each respondent we will collect behavioral (i.e., actions) and survey-based outcomes as specified in the pre-analysis plan.
Sample size (or number of clusters) by treatment arms
We expect each of the three groups (1 control and 2 treatment) to be approximately of the same size.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Power calculations are attached to the pre-analysis plan.
