Noting the lack of “anti-man” bias research in the 2016 election, Zigerell (2019) argued that a relative lack of conservatives in political science can lead to bias in publications against political science research supporting conservative viewpoints. This article offers an alternative explanation for this lack of research: that this research produces null findings and therefore is subject to the “file-drawer problem,” in which null effects are less likely to be published than positive effects. Using data from the 2016 American National Election Studies, I provide an illustrative example to support this claim and suggest some solutions.
