Abstract
This auxiliary experiment extends our previous experiments, pre-registered in AEARCTR-0005308 and AEARCTR-0005462. This experiment aims to show that the "justifications" considered in our previous experiments are persuasive: that is, that respondents exposed to them change their behavior in the expected direction.

Interventions

Intervention(s)
This auxiliary experiment extends our previous experiments, pre-registered in AEARCTR-0005308 and AEARCTR-0005462. This experiment aims to show that the "justifications" considered in our previous experiments are persuasive: that is, that respondents exposed to them change their behavior in the expected direction.

The intervention is a standard information provision experiment. Control respondents are not exposed to information about a political topic; treated respondents are exposed to this information. All respondents are then asked to indicate their support for the position.

We conduct the experiment in two contexts. Conservative respondents watch a video featuring Fox News anchor Tucker Carlson discussing the link between illegal immigration and crime, then indicate their support for immediately deporting all illegal Mexican immigrants. Liberal respondents read an article discussing the likely adverse effects of defunding the police, then indicate their support for defunding the police.
