Abstract:
We make a two-pronged proposal to (i) strengthen the incentives for replication work and (ii) better organize and draw attention to the replications that are conducted. First we propose that top journals publish short “replication reports.” These reports could summarize novel work replicating an existing high-impact paper, or they could highlight a replication result embedded in a wider-scope published paper. Second, we suggest incentivizing replications with the currency of our profession: citations. Enforcing a norm of citing replication work alongside the original would provide incentives f

Abstract:
Recent controversies in psychology have spurred conversations about the nature and quality of psychological research. One topic receiving substantial attention is the role of replication in psychological science. Using the complete publication history of the 100 psychology journals with the highest 5-year impact factors, the current article provides an overview of replications in psychological research since 1900. This investigation revealed that roughly 1.6% of all psychology publications used the term replication in text. A more thorough analysis of 500 randomly selected articles revealed th

In methodological and practical debates about replications in science, it is (often implicitly) assumed that replications will affect public trust in science. In this preregistered experiment ( N = 484), we varied (a) whether a replication attempt was successful or not and (b) whether the replication was authored by the same, or another lab. Results showed that ratings of study credibility (e.g. evidence strength, ηP2 = .15) and researcher trustworthiness (e.g. expertise, ηP2 = .15) were rated higher upon learning of replication success, and lower in case of replication failure.

The theory of mind is a psychological concept that refers to the awareness of one’s mental states and others’. In the seminal study conducted by Kidd and Castano (2013), the researchers found that reading literary fiction led to better performance in the theory of mind test relative to reading popular fiction, nonfiction, or reading nothing at all.

To accomplish this, psychology journals could publish replication reports in files that are electronically linked to reports of the original research. Second, replications should get cited.

Included articles were assessed for fidelity to the original study using 5 categories: Identical, Substitutable, In-class, Augmented, and Out-of-class; and 7 IMPISCO domains: Investigators (I), Method (M), Population (P), Intervention (I), Setting (S), Comparator (C), and Outcome (O). A fidelity score and heat map were g

This paper discusses recent trends in the use of replications in economics. We include the results of recent replication studies that have attempted to identify replication rates within the discipline. These studies generally find that replication rates are relatively low. We then consider obstacles to undertaking replication studies and highlight replication initiatives in psychology and political science, behind which economics appears to lag.

Abstract:
Conducting a replication study is a valuable way for undergraduate students to learn about the scientific process and gain research experience. By promoting the evaluation of existing studies to confirm their reliability, replications play a unique, though often underappreciated, role in the scientific enterprise. Involving students early in this process can help make replication mainstream among the new generation of scientists. Beyond their benefit to science, replications also provide an invaluable learning ground for students, from encouraging the development of critical thinking to emphas

Abstract:
Replication is held as the gold standard for ensuring the reliability of published scientific literature. But conducting direct replications is expensive, time-consuming, and unrewarded under current publication practices. So who will do them? The authors argue that students in laboratory classes should replicate recent findings as part of their training in experimental methods. In their own courses, the authors have found that replicating cutting-edge results is exciting and fun; it gives students the opportunity to make real scientific contributions (provided supervision is appropriate); and

Abstract:
Introduction Previous studies about the replicability of clinical research based on the published literature have suggested that highly cited articles are often contradicted or found to have inflated effects. Nevertheless, there are no recent updates of such efforts, and this situation may have changed over time. Methods We searched the Web of Science database for articles studying medical interventions with more than 2000 citations, published between 2004 and 2018 in high-impact medical journals. We then searched for replications of these studies in PubMed using the PICO (Population, Interven

Abstract:
Replication is a critical aspect of scientific inquiry that presents a variety of challenges to researchers, even under the best of conditions. We conducted a review of replication rates in special education journals similar to the review conducted by Makel et al. in this issue. Unknowingly conducting independent reviews allowed for an unexpected opportunity to examine how two teams of researchers attempted to replicate a previously published study and explore similarities and differences between the outcomes. In our review, we identified 70 replication studies published between 1997 and 2013,

Abstract:
Replications are often taken to play both epistemic and demarcating roles in science: they provide evidence about the reliability of fields’ methods and, by extension, about which fields “count” as scientific. I argue that, in a field characterized by a high degree of theoretical openness and uncertainty, like comparative cognition, replications do not sit well in these roles. Like other experiments conducted under conditions of uncertainty, replications are often equivocal and open to interpretation. As a result, they are poorly placed to deliver clear judgments about the reliability of compa

Abstract:
Recent discussions of the influence of publication bias and questionable research practices on psychological science have increased researchers’ interest in both bias-correcting meta-analytic techniques and preregistered replication. Both approaches have their strengths: For example, meta-analyses can quantitatively characterize the full body of work done in the field of interest, and preregistered replications can be immune to bias. Both approaches also have clear weaknesses: Decisions about which meta-analytic estimates to interpret tend to be controversial, and replications can be discounte

Abstract In this article, we review the ways in which replication has been and could be featured in consumer behavior, using Journal of Consumer Research as a specific setting. We present a framework for thinking about the generalizability of research findings and differentiate various potential benefits that replication can have for understanding variability in consumer research findings. We then define four different types of replications, describe how researchers can use these approaches to produce distinct benefits, and give guidance regarding conducting, interpreting, and the potential co

Fernbach et al. (2013) found that political extremism and partisan in-group favoritism can be reduced by asking people to provide mechanistic explanations for complex policies, thus making their lack of procedural-policy knowledge salient. Given the practical importance of these findings, we conducted two preregistered close replications of Fernbach et al.’s Experiment 2 (Replication 1a: N = 306; Replication 1b: N = 405) and preregistered close and conceptual replications of Fernbach et al.’s Experiment 3 (Replication 2: N = 343).
