Background: Registered Reports are publications in which study proposals are peer reviewed and pre-accepted before the study is ran. Their adoption in other disciplines has been found to promote research quality and save time and resources. Objectives: We offer a brief introduction to Registered Re- ports and their expected benefits for visualization research. We then report on a survey on the attitudes held in the Visualization community to- wards Registered Reports. Method: We ran an online survey that was open from October 7, 2021 until October 24, 2021. We received 105 responses from visualization researchers. Results: Most respondents expressed interest in Registered Reports as an additional submission format. Ju- nior researchers as well as researchers with prior experience of preregistration tended to be more in- clined to adopt this format. However, qualitative feedback highlights several perceived drawbacks and worries about Registered Reports, such as low suitability for some types of research, and increased workload for reviewers and authors. Conclusion: While many respondents expressed interest in (and sometimes enthusiasm for) Registered Re- ports, many also voiced concerns that should be considered and discussed in the community.
