Since data for both Study 1 and Study 2 (Serbian and Bosnian subsample) were collected as part of larger projects, we provide the full material set (including questions that were not used in the present research).
More information on Study 1 can be found [here][1], and more infomation on Study 2 - Serbian subsample [here][2]. Study 2 on the BiH subsample is essentially a conceptual replication of Study 1 (with some variables added from Study 2 - Serbian sample), while Study 2 - UK subsample was collected primarily for this project.
