Pre-analysis plan for a study on affective polarization in a multiparty setting

This is a pre-analysis plan for a study on affective polarization in the Norwegian Citizen Panel. I fielded a replication of the experiment by Klar, Krupnikov and Ryan (2018) in a probability based panel of Norwegian adults. I customized the design for a multiparty setting with nine parties and investigate to what degree Norwegians are affectively polarized.
