This repository includes two datasets: the first dataset pools all the field experiments (randomized controlled trials) by political scientists, pre-registered between 2014 and 2019 across three main social science registries: the Evidence in Governance and Politics (EGAP), the American Economic Association’s registry for randomized controlled trials (AEA) and the Registry for International Development Impact Evaluations (RIDIE). The second dataset records all field experiments published in top political science journals between 1906 and 2020, based on a search engine developed by Wilson and Knutsen (2020).
