This World Bank blog post explores the Social Science Prediction Platform (SSPP), an innovative tool developed by the Berkeley Initiative for Transparency in the Social Sciences (BITSS) to enhance the rigor and transparency of development research. The SSPP enables researchers, policymakers, and experts to make and compare predictions about the outcomes of impact evaluations before results are known. By systematically collecting these forecasts, the platform helps assess expert judgment, improve study design, and refine the interpretation of findings. The article highlights how this approach can strengthen evidence-based policymaking, reduce publication bias, and increase the credibility of social science research.
