Recent contributions have questioned the credibility of quantitative communication research. While questionable research practices are believed to be widespread, evidence for this claim is primarily derived from other disciplines. Before change in communication research can happen, it is important to document the extent to which QRPs are used and whether researchers are open to the changes proposed by the so-called open science agenda. We conducted a large survey among authors of papers published in the top-20 journals in communication science in the last ten years (N=1039). A non-trivial percent of researchers report using one or more QRPs. While QRPs are generally considered unacceptable, researchers perceive QRPs to be common among their colleagues. At the same time, we find optimism about the use of open science practices in communication research. We end with a series of recommendations outlining what journals, institutions and researchers can do moving forward.

Recent contributions have questioned the credibility of quantitative communication research. While questionable research practices (QRPs) are believed to be widespread, evidence for this belief is, primarily, derived from other disciplines. Therefore, it is largely unknown to what extent QRPs are used in quantitative communication research and whether researchers embrace open research practices (ORPs). We surveyed first and corresponding authors of publications in the top-20 journals in communication science. Many researchers report using one or more QRPs. We find widespread pluralistic ignorance: QRPs are generally rejected, but researchers believe they are prevalent. At the same time, we find optimism about the use of open science practices. In all, our study has implications for theories in communication that rely upon a cumulative body of empirical work: these theories are negatively affected by QRPs but can gain credibility if based upon ORPs. We outline an agenda to move forward as a discipline.
