Abstract
We test a fundamental assumption underlying the literature on information aggregation and deliberation: that people update their
beliefs when listening to peers. We investigate whether this assumption holds in online deliberation among strangers prior to a ballot on rent control. In a two-wave survey experiment, we collect voting intentions and textual data from chat interactions before the ballot and self-reported votes after the ballot. The study design randomly assigns chat-group compositions.

Experimental Design
Experimental Design
Half of the participants are randomly assigned to groups of five and have an online deliberation about how they should vote on the California rent control initiative. The other half in the control are only asked to write one argument for and one argument against rent control. We have a baseline survey and a follow-up survey in which we ask about voting intentions, demographics, media consumption, and political orientation among other questions.
