We reproduce Shoub, Kelsey, Katelyn E. Stauffer, and Miyeon Song (May 2021). "Do Female Officers Police Differently? Evidence from Traffic Stops," with alternative specifications and interpretation of the results. While our reproduction confirms that female police officers are less likely to...

This study pushes our understanding of research reliability by reproducing and replicating claims from 110 papers in leading economic and political science journals. The analysis involves computational reproducibility checks and robustness assessments. It reveals several patterns. First, we...

The social sciences face a replicability crisis. A key determinant of replication success is statistical power. We assess the power of political science research by collating over 16,000 hypothesis tests from about 2,000 articles. Using generous assumptions, we find that the median analysis has...

The scientific method is predicated on transparency - yet the pace at which transparent research practices are being adopted by the scientific community is slow. The replication crisis in psychology showed that published findings employing statistical inference are threatened by undetected...

This article reviews and summarizes current reproduction and replication practices in political science. We first provide definitions for reproducibility and replicability. We then review data availability policies for 28 leading political science journals and present the results from a survey...

We computationally reproduce the central findings in Mehmood (2022), which studied the effect of a 2010 reform in Pakistan replacing the presidential appointment of high-court judges with peer appointments. Mehmood leveraged judicial records interpreted and coded by lawyers in Pakistan at the...

We provide a reproduction and replication of Brutger (2024), which examines the effects of the University of California, Berkeley's Pipeline Initiative in Political Science (PIPS) program on five self-reported outcomes related to interest and preparation towards pursuing graduate school. We are...
