Abstract
This research project would use a 2x2 factorial experiment to analyze how norms of similarity can decrease perceived threat and increase support for policing reforms. Drawing inspiration from previous experiments (Smith et al, 2012), the treatments will consist of the presentation of a summary or news article discussing results from an ostensible study assessing ingroup and outgroup attitudes and behaviors. The content of the treatments will be customized based on the findings of stage one.

Experimental Details

Interventions

Intervention(s)
500 white VA participants will be randomly assigned to one of 4 treatment groups or the control group. We will use complete random assignment to ensure that there is a similar number of participants (approximately 100 in each treatment group and 100 in control group). For each case, we will circulate an expression of interest to potential participants (Online through MTurk) in the US,), including a screening survey, which we will use to establish a list of suitable participants to meet a political affiliation quote.

For each case, we will circulate an expression of interest to potential participants (Online through MTurk) in the US,), including a screening survey, which we will use to establish a list of suitable participants to meet a political affiliation quote. We will then use the “ri” package in R to complete the random assignment.
