These data were collected through a randomized experimental trial to test the effectiveness of different message formats on debunking a misconception about rent controls. Three message formats were tested: a non-refutational text (NRT), a refutational text (RT) and a refutational video (RV). A first pre-analysis plan (PAP) was preregistered at AsPredicted Registry, Wharton Credibility Lab (University of Pennsylvania) on July 4, 2020. This PAP included the RT and NRT conditions. The PAP corresponding to the RV condition was preregistered at AsPredicted Registry on July 3, 2021. All three conditions were preregistered before running the corresponding experiment sessions. Anonymized copies of the preregistered plans are available at https://aspredicted.org/blind.php?x=uv2t69 and https://aspredicted.org/blind.php?x=4n78sy. The experiments were run on-line by the LINEEX Laboratory for Research in Behavioural Experimental Economics of the University of Valencia (Spain).
