Publication bias has been recognized as a threat to the validity of meta-analytic findings and scientific knowledge in general. Given the recent rise in meta-analytic research in communication, how well publication bias concerns are addressed by communication meta-analysts merits attention. In this essay, after a brief overview of publication bias and some major methods of assessment, we provide a systematic review of meta-analyses published in six major communication journals between 2005 and 2018. The review focuses on two aspects of addressing publication bias in meta-analyses: (a) reducing the potential impact of bias via an inclusive literature search; and (b) empirically assessing the extent and impact of bias in meta-analytic findings. Our review shows that the current practices in communication meta-analyses are inadequate in both aspects. We offer recommendations on ways of improving practices in meta-analyses, as well as in research and publication processes, to better safeguard knowledge claims.
