Scientists (such as at Cochrane, and METRICS) have made a lot of progress in terms of the development of the field of meta-analysis, which is allowing us to take a broader look at what methods are being used, and which methods produce the best results. In that process we're going to learn a lot as well about what produces less reliable results. This knowledge will be used to guide future research.
Meta-research is an evolving scientific discipline that aims to evaluate and improve research practices. It includes thematic areas of methods, reporting, reproducibility, evaluation, and incentives (how to do, report, verify, correct, and reward science). Much work is already done in this growing field, but efforts to-date are fragmented. We provide a map of ongoing efforts and discuss plans for connecting the multiple meta-research efforts across science worldwide. - METRICS
