200 Researchers, 5 Hypotheses, No Consistent Answers

(Wired) – These questions could be answered in many different ways; these, in turn, may lead to vastly different findings. A new crowdsourced experiment—involving more than 15,000 subjects and 200 researchers in more than two dozen countries—proves that point. When various research teams designed their own means of testing the very same set of research questions, they came up with divergent, and in some cases opposing, results. The crowdsourced study is a dramatic demonstration of an idea that’s been widely discussed in light of the reproducibility crisis—the notion that subjective decisions researchers make while designing their studies can have an enormous impact on their observed results.
