A Manifesto for Reproducible Science. Before we move on to replicability and replication in the humanities, I would like to make two preliminary points. … One might think it likely that a replication of any study by members of the one group would lead to substantially different results if carried out by members of the other group. What this means is that in some humanistic disciplines, replicability is still a desideratum and replicability surely is still a positive property, but the absence of replicability because of severe limits on the possibility of replication is not necessarily a reason to discard that study. Some philosophers of science and scholars in research integrity use the term “transparency” for what I dub “replicability” here.Footnote 21 Clearly, replicability, as I understand it here, has much to do with transparency: a study can be replicated only if the researchers are sufficiently transparent about the data, the method, the inferences, and so on. For a similar definition, see KNAW [10], 18; NSF [17], 4–5. Despite the many challenges, the “worst case scenario” has not been actualized. These two points apply a forteriori when other rather than the same humanistic scholars apply the same method of interpretation (the hermeneutical approach or a historical-critical methodology) to the same text. There may, therefore, be somewhat less of a social and epistemic urge to carry out replication studies in the humanities. Dordrecht: Springer; 2012. But they are everything we need to take seriously when it comes to entertainment, enjoyment, and psychological satisfaction. I think this is not entirely true: some humanistic disciplines, such as metaphysics, are also concerned with objects that do not have meaning or value, such as numbers or the nature of space-time. The committee will provide definitions of "reproducibility" and "replication" accounting for the diversity of fields in science and engineering. https://doi.org/10.1136/bmj.k96 published January 31st. Essig L, Moorti S. Only a Rube Would Believe Gender Studies Has Produced Nothing of Value: The Chronicle of Higher Education; 2018. I said “roughly,” because, as Brian Earp has argued in more detail, things are never so simple when it comes to falsification: even if an attempt at falsification has taken place and the new data seem to count against the original hypothesis, one might often just as well, say, question an auxiliary assumption, consider whether a mistake was made in the original study, or wonder whether perhaps the original effect is a genuine effect but one that can only be obtained under specific conditions.Footnote 23 Nevertheless, falsification is often still considered as a useful heuristic in judging the strength of a hypothesis.Footnote 24 Now, the obvious difference with the issue at hand is that, even though both falsifiability and replicability are desiderata, replication is a good thing, because it makes it, all else being equal, likely that results are true, whereas falsification is in a sense a bad thing, because it makes it likely that a theory is false.Footnote 25. The DataVerse Network project (8) promotes sharing, citing, using, and archiving scientific data for reproducible research. Cookies policy. Research reliability can be … Subsequently, I give a more detailed case for thinking that replication in the humanities is possible. Reliability and Replicability Previous Next. One may think, for instance, that there are no such facts about value and meaningFootnote 39 or that they are all socially constructed, so that it would not be right to say that the humanities can uncover them.Footnote 40 This is, of course, a controversial issue. icon-arrow-top icon-arrow-top.

Migraine and risk of cardiovascular diseases: Danish population based matched cohort study. 2018;26(1):46–65. On a personal note, I have tried to reproduce studies while working with a statistician and most life science journal articles do not include enough details to exactly recreate analysis unless they include their script (e.g., Python, SAS, or R code used to analyze the data). Nature. In economics, for instance, we find the economics of the Saltwater school, the economics of the Freshwater school, and, more rarely, institutional economics, Austrian economics, feminist economics, Marxian economics, and ecological economics.

(A) The committee will assess research and data reproducibility and replicability issues, with a focus on topics that cross disciplines. If one has the right background knowledge and skills, one can fairly easily study the same data or collect further data in order to replicate this study.Footnote 45.

Research Reliability Reliability refers to whether or not you get the same answer by using an instrument to measure something more than once. Alternative ways of thinking about reliability and replicability have been suggested by qualitative methodologists. 2016;533:452–4. A fourth option, not mentioned in the report, is to carry out a replication with the same data and a new or revised research protocol. 2015;349:6351. https://doi.org/10.1126/science.aac4716. The ability for procedures and findings to be reproduced and repeated. In: Morin J-F, Olsson C, Atikcan EO, editors. It is important to use a data collection method that will help answer your research question(s). Being able to duplicate published research results is an important process of conducting research whether to build upon these findings or to compare with them. 2018 https://knaw.nl/en/news/publications/replication-studies, last visited May 1st 2018. I would be happy, though, to embrace the definitions given of these terms in the KNAW Advisory Report, viz. The report recommends a range of steps that stakeholders in the research enterprise should take to improve reproducibility and replicability, including: All researchers should include a clear, specific, and complete description of how the reported results were reached. However, it is rather controversial exactly what this hoax shows about the epistemic status of these fields in the humanities.Footnote 49 Some have argued that the results would have been similar in pretty much any other empirical discipline,Footnote 50 and still others that we cannot conclude anything from this hoax, since there was no control group.Footnote 51. 2014;45:142–52. Reproducibility and replicability of research results have gained a lot of interest recently with assessment studies being led in various fields, and they are often seen as a trigger for better result diffusion and transparency. Let us define “replication study” as follows: A replication study is a study that is an independent repetition of an earlier, published study, using sufficiently similar methods (along the appropriate dimensions) and conducted under sufficiently similar circumstances.Footnote 14. How we should think of replication in the humanities is something that has not received any attention so far, except for a couple of articles that I co-authored with Lex Bouter.Footnote 10 Maybe this is because it is questionable whether replication is even possible in the humanities. After all, it is possible (i) to compare the original data (say, certain texts, archeological findings, the occurrence of certain verbs, and so on), the conclusions of the original study and the replication study, and everything in between, (ii) to take a qualitative approach and sometimes even, if not a rigorous statistical approach, at least a more quantitative approach, e.g., by counting the number of verbs in Shakespeare’s plays that end in “th” or “st,” and (iii) to define how much similarity between the original results and the results in the replication study is required for something’s being a successful replication, even though this will be harder or impossible to quantify, in opposition to many studies in, say, psychology and economics. One of the most important features of a scientific research paper is that the research must be replicable, which means that the paper gives readers enough detailed information that the research can be repeated (or 'replicated'). Opener. Third and finally, the definition states that the methods used and the circumstances in which the study is carried out should be “sufficiently similar.” That means that they need not be identical—that may be the case (or something very close to that), but that is not required for a replication study. Nuzzo R. Fooling ourselves. Engber, Daniel. Scientists and various news platforms have, over the last few years, increasingly been speaking of a replication crisis in various academic disciplines, especially the biomedical Footnote 1 and social sciences.Footnote 2 The main reason for this is that it turns out that large numbers of studies cannot be replicated, that is (roughly), they yield results that appear not to support, or to count against, the validity of the original finding.Footnote 3 This has been and still is an important impulse for composing and adapting various codes of research integrity. Talk to your advisor and/or colleagues about how to address the new standards as you design your studies. One might think that the inevitably normative nature of these humanistic objects makes replication impossible. Wright NT. Peels R, Bouter L. Replication drive for humanities. Here, I will not delve into this complex issue, which would merit a paper or more of its own. For overviews of such causes, see AMS [8], 5, 16–21; IAP [9], 1; KNAW, 23–24 [10]; Munafò et al. In this paper, Smith argues that there is actually no systematically acquired evidence for thinking that peer review is a good quality assurance mechanism and that we do have good evidence for thinking that peer review has a large number of downsides. Lindsay, JA., P Boghossian, H Pluckrose. By replicating an empirical study, say, on whether or not patients with incident migraine, in comparison with the general population, have higher absolute risks of suffering from myocardial infarction, stroke, peripheral artery disease, atrial fibrillation, and heart failureFootnote 35 one can, in principle, apply the same method or a similar method to new patients (say, a population from a different country). If so, they are not replicable, but not because of any scholarly shortcoming. Second, exactly what is it that should be replicable in a good replication study? In more recent times, the rise of evidence-based medicine has led to improved clinical practice through meta-analyses, systematic reviews and the formation of clinical guidelines. The closer the replication study topic is to the topic of the original study, the more it counts as a replication study, and, similarly, for method, samples, conditions, and so on. Yes. Novel ideas, even without experiments or good results, can have a big impact. This means that various other kinds of dependence are perfectly legitimate for a replication study. Search form. The animal care and use program also assumes a principal role in assuring the replicability, reproducibility, and reliability of animal research by developing and implementing well-defined processes that control various extrinsic factors (that is, those external to the animal), reducing sources of variability that may confound study outcomes. Now, imagine, on the other hand, that it is possible to uncover knowledge about objects with value and meaning and even about those aspects of those objects that specifically concern value and meaning. 2016;8(341):ps12. New York: Norton; 2012. Thus, replicability is a desideratum for at least many studies in the quantitative empirical sciences (I return to the humanities below): we want them to be set-up and described in such a way that, in principle, we could carry out a replication study. Book. Cambridge: Cambridge University; 1997. iv) Replicability Replicability in scientific research cohorts that the results of the research or the tests of the hypothesis should be supported again and again when the research is repeated in other similar circumstances, the Replicability gives confidence in our research design and hence makes it scientific. If the paper explained in detail how the research was carried out, other researchers would be able to repeat the research and either confirm or oppose the findings. 1. History and Theory. Thus, even though many humanistic studies would be replicable, carrying out a replication study would in the majority of cases lead to different results. It means that a study should produce the same results if repeated exactly, either by the same researcher or… Parts of linguistics study grammatical structures that, by definition, have many instances, as will be clear from any introduction to morphosyntax.Footnote 33 As to the quantitative empirical sciences: the big bang, the coming into existence of life on earth, space-time itself, and many other phenomena studied in the empirical sciences are unique phenomena: there is only one instance of them. that claimed that an AI system could beat human radiologists in achieving higher robustness and speed in breast cancer screening. A call for action to improve the reproducibility of biomedical research. Res Integr Peer Rev 4, 2 (2019). resources, since studies that cannot be consistently replicated are less likely to be true, (iii) results that are not replicable are, if they are applied, more likely to cause harm to individuals, animals, and society (e.g., by leading to mistaken economic measures or medicine that is detrimental to people’s health), and (iv) if too many results turn out not to be replicable, upon attempting to replicate them, that will gradually erode public trust in science.Footnote 7.
