The Political Science Replication Initiative (PSRI) aims to promote replication research in political science. It was co-founded by Nicole Janz, Stephanie Wykstra and Seth Werfel. It is currently run by Nicole Janz, Assistant Professor at the University of Nottingham. On this page we point to resources on reproducibility and replications, and we provide an online database of replication studies in political science. As research transparency grows within the discipline, so does the ability to explore previous findings through re-analysis and robustness checks. Replication studies are an important element in scientific discovery that allow researchers to evaluate the validity and scope conditions of their proposed causal relationships. At the same time, replications tend to remain unpublished ('file drawer problem'), and even if they are published, they are not easily detectable because they rarely have the term 'replication' in the title or abstract. 

If you are affiliated with a political science department and have conducted a replication study, we invite you to submit it here. Our submission process is simple: 

1. Read our submission guidelines to ensure that your replication study is eligible for posting in the repository.
2. Go to the replications tab on this site, and click "create a new study" in the upper right-hand corner of the screen.

3. You will be prompted to complete a form with your replication study metadata, and upload your replication code and data to Dataverse.

If the submission complies with all requirements, it will be accepted into the Dataverse. If your submission is incomplete, you will receive an email with further instructions.

If you have already posted your replication materials to your own Dataverse, and would like to have your Dataverse linked so that it appears in the compiled list, please email us with a request.
