 ## **Motivation**
 
 The purpose of collating these reversal effects in social science is to encourage educators to incorporate replications of these effects into their students' project (e.g., third-year, thesis, course work) to provide them the opportunity to experience the research process directly, assess their ability to perform and report scientific research, and to help evaluate the robustness of the original study, thereby also helping them become good consumers of research. The below crowdsourced and community-curated resource aims to satisfy three of [FORRT’s Goals](https://forrt.org/about/mission/):
