Aronow and Fredrik Sävje, we reanalyze all studies published in the top journals in political science that use a regression discontinuity (RD) design. <LINK> [1/4]', 'We show that the literature demonstrates some pathological behavior consistent with selective reporting of findings. The figure below demonstrates that findings cluster just at or just above the t-statistic threshold of 1.96 (i.e. a p-value of less than or equal to 0.05). [2/4] https://t.co/AiONuxYIEu', 'Reanalysis of these studies using modern, automated methods [see: https://t.co/EPIW73zx1W] shows that, while the point estimates are relatively stable, uncertainty has been been systematically understated. [3/4]', 'Retrospective power analyses demonstrate that most studies were underpowered to detect all but large effect sizes. We conclude that many published findings using the RD design are exaggerated if not altogether spurious. [4/4]', ""@guygrossman We included filtering by reviewers/editors in the phrase 'selective reporting.' Perhaps 'selective reporting or publishing' would have been clearer. That said, we do explicitly note publication filtering and selective reporting in the body of the paper.""]",21,09,1171
