Experimental Details

Interventions

Intervention(s)
We present an issue with two mutually exclusive sides to the participants and collect their attitudes and opinions on the issue. We implement two interventions: whether subjects are initially exposed to complete or one-sided evidence on the issue and whether subsequent arguments from both sides are exogenously provided to participants or can be endogenously selected.
