Alan S. Gerber, Gregory A. Huber, Daniel R. Biggers, David J. Hendry (2016). Context unlikely the cause of nonrobustness. Proceedings of the National Academy of Sciences, 113(43) E6549-E6550; DOI: 10.1073/pnas.1610539113.
Bryan et al. explain our null results by asserting that the treatment they developed should have no effect unless certain conditions hold; we learn from Bryan et al.’s letter that the election must be high-profile or competitive. However, this is an ex-post argument, absent from their 2011 article. We provide four reasons our null findings are unlikely to stem from political-context differences.
