Irreproducibility Report
A reproducibility crisis afflicts a wide range of scientific and social-scientific disciplines, from epidemiology to social psychology. Improper use of statistics, arbitrary research techniques, lack of accountability, political groupthink, and a scientific culture biased toward producing positive results together have produced a critical state of affairs. Many supposedly scientific results cannot be reproduced in subsequent investigations. // This study examines the different aspects of the reproducibility crisis of modern science. The report also includes a series of policy recommendations, scientific and political, for alleviating the reproducibility crisis.
