Identifying Reproducible Research Using Human-in-the-loop Machine Learning
Research quality thrives under healthy skepticism where scientists retest hypotheses creating higher levels of confidence in the original findings and a sturdy foundation for extending work. Recent attempts to sample scientific research in psychology, economics, and medicine however have shown that more scientific papers fail than pass manual replication tests. Consequently, several attempts have been made to find ways to efficiently extend replication studies, including new statistics, surveys, and prediction markets. However new statistics have been very slowly adopted and the high costs associated with surveys and prediction markets makes these methods impractical for estimating the reproducibility of more than a few hundred studies out of the vast stock of millions of research papers that are used as building blocks for current and future work. The research aims to develop metrics and tools to help make replication studies of existing work more efficient with one additional benefit: to help scientists, scholars, and technologists self-evaluate their work before publishing it.
This project combines efforts to create new datasets, ‘reproducibility’ metrics, and machine learning models that estimate a confidence level in the reproducibility of a published work. The deliverables will include new datasets covering the success and failure of hundreds of scientific papers in psychology and economics and their related subfields. The metrics will go beyond a binary classification of whether a publication is estimated to be reproducible or not. They will quantify a level of confidence that the work is likely to be reproducible. The machine learning models will also help scientists interpret and explain confidence scores, which aid scientists in learning about the factors that correlate with reproducibility. In all three areas, the project will aim to provide scientists with better tools to evaluate the reproducibility of their own and others’ work, creating a better foundation of knowledge for advancing research.
