It is uncontroversial that ecosystems and species possess a wide variety of instrumental values (e.g., cultural value, recreational value, medicinal value, spiritual value, transformational value, natural resource value, and ecosystem services value). FINDING 5-3: Studies that directly measure replicability take substantial time and resources. Engineering, Computational Fluid Dynamics (, Full replication studies of previously published results on bluff-body aerodynamics, using four different computational methods. If species and ecosystems have objective intrinsic value, then their value is discovered by human valuers, it is not created by them. Determining the intrinsic value of something, on the other hand, is often more difficult. Taylor, P. Respect for Nature: A Theory of Environmental Ethics. Attempt to replicate 10 psychology studies in one online session. Rescher urges caution to those who would settle such disputes through censorship and suppression of views that they fear might damage the public image of science. Unlike the typical expectation of reproducibility between two computations, expectations about replicability are more nuanced, and in some cases a lack of replicability can aid the process of scientific discovery. Of the 18 studies, 2 analyses (11%) were replicated; 6 were partially replicated or showed some discrepancies in results; and 10 could not be replicated. In philosophy and ethics, an end, or telos, is the ultimate goal in a series of steps. However, a restrictive and unreliable approach would accept replication only when the results in both studies have attained statistical significance, that is, when the p-values in both studies have exceeded a selected threshold. Around the same time, in a case that came to light in the Netherlands, social psychologist Diederick Stapel had gone from manipulating to fabricating data over the course of a career with dozens of fraudulent publications. Another common example relates to money. As Rescher states in the final section of his essay, "It is a regrettable fact that too many persons, both scientists and students of the scientific method, have had their attention focused so sharply upon the abstracted 'logic' of an idealized 'scientific method' that this ethical dimension of science has completely escaped their notice. Cambridge, UK: Cambridge University Press, 1989. Why does it matter for conservation biology whether species, ecosystems or organisms have intrinsic value. Further discussion of ethics and values issues related to the "doing" and "using" of science will be found in connection with the examples used in Chapters 2 and 3, and in more detail in association with the case studies presented in Chapter 4. Values dictate how a person feels, acts, and believes about important topics. For example, Einstein's rejection of quantum mechanics as an irreducible description of naturesummarized in his insistence that "God does not play dice"seems to have been based largely on an aesthetic conviction that the physical universe could not contain such an inherent component of randomness. Errors may also be made by researchers despite their best intentions (see Box 5-2). Apart from specific efforts to replicate others studies, investigators will typically confirm their own results, as in a laboratory experiment, prior to, TABLE 5-1 Examples of Replication Studies. Several tools are being developed to compare a distribution of results to what that distribution would look like if all claimed effects were representative of the true distribution of effects. Some have distinguished between the context of discovery and the context of justification (Reichenbach, 1938), while others have argued that the distinction is on a spectrum rather than categorical. For example, there are ethical concerns related to the relative importance of cooperation and competition in scientific research, and the related issue of the extent to which scientists are obliged to share their data. According to the definition adopted by the U.S. federal government in 2000, research misconduct is fabrication of data, falsification of data, or plagiarism in proposing, performing, or reviewing research, or in reporting research results (Office of Science and Technology Policy, 2000, p. 76262). CONCLUSION 5-4: The occurrence of non-replicability is due to multiple sources, some of which impede and others of which promote progress in science. Steven Goodman, the codirector of the Meta-Research Innovation Center at Stanford University (METRICS), suggested that the focus ought not be on the rate of non-replication of individual studies, but rather on cumulative evidence provided by all studies and convergence to the truth. "Explicit and implicit values," in The Endangered Species Act at Thirty: Conserving Biodiversity in Human-Dominated Landscapes, Vol. whose selection probabilities are unknown [makes it] difficult to estimate how representative they are of the [target] population (Dillman, Smyth, and Christian, 2014, pp. Figure 5-2 illustrates the combinations of complexity and controllability. HARKing applies to confirmatory research that incorrectly bases the hypothesis on the data collected and then uses that same data as evidence to support the hypothesis. Sex-linked. Misuse of statistical testing often involves post hoc analyses of data already collected, making it seem as though statistically significant results provide evidence against the null hypothesis, when in fact they may have a high probability of being false positives (John et al., 2012; Munafo et al., 2017). Suppose, for example, that the mass of a sample of gold was measured on one balance and found to be 1.896 g. On a different balance, the same sample was found to have a mass of 1.125 g. Which was correct? One source of disputes concerning credit for research ideas and ownership of intellectual property is the peer review process. Cambridge, UK: Cambridge University Press, 2005. Therefore, replicability studies included as part of the scientific literature but not cited as such add to the difficulty in assessing the extent of replication and non-replication. We repeat our definition of replicability, with emphasis added: obtaining consistent results across studies aimed at answering the same scientific question, each of which has obtained its own data. as the purkinje shift (i.e., a change in sensitivity of the human eye under different levels of illumination). The first five articles have been published; two replicated important parts of the original papers, one did not replicate, and two were uninterpretable. Scientific uncertainty is a quantitative measurement of variability in the data. 9. 3 Understanding Reproducibility and Replicability, Appendix A: Biographical Sketches of Committee Members and Staff, Appendix B: Agendas of Open Committee Meetings, Appendix C: Recommendations Grouped by Stakeholder, Appendix D: Using Bayes Analysis for Hypothesis Testing, Appendix E: Conducting Replicable Surveys of Scientific Communities, A group of 20 research teams performed replication studies of 40 experimental philosophy studies published between 2003 and 2015. Click here to buy this book in print or download it as a free PDF, if available. It also demonstrates that non-replicability can result in advances in scientific knowledge. Environmental Ethics 14, 265-273 (1992). This uncertainty can be categorized in two ways: accuracy and precision. Not only is the obvious point made that scientists are members of society, and are therefore confronted by questions related to the social uses of science, a more controversial ethical claim is made by those who take issue with Rescher's disclaimer. Reflect on what these values mean to you. O'Neill, J. Ecology, Policy, and Politics: Human Well-Being and the Natural World. For more information on how inherent risk heat is calculated, see Assessing risk. As noted in a recent study on retraction trends (Brainard, 2018, p. 392), Overall, nearly 40% of retraction notices did not mention fraud or other kinds of misconduct. The National Science Foundation reports that accusations that a peer reviewer appropriated an experimental or theoretical idea or result from a research proposal or paper he or she was sent to evaluate, is the largest category of scientific misconduct complaints that it receives. Many direct replication studies are not reported as such. Minteer, B. Intrinsic value for pragmatists. Every scientific inquiry encounters an irreducible level of uncertainty, whether this is due to random processes in the system under study, limits to researchers understanding or ability to control that system, or limitations of the ability to measure. The results of the massive international Human Genome Project will further expand the need to confront a long list of extremely controversial social uses of this work. However, in 2013, with access to Reinhart and Rogoffs original spreadsheet of data and analysis (which the authors had saved and made available for the replication effort), researchers reanalyzing the original studies found several errors in the analysis and data selection. When non-replication of results due to sources such as those listed above are investigated and resolved, it can lead to new insights, better uncertainty characterization, and increased knowledge about the systems under study and the methods used to study them. 10 journals explicitly note they publish replications; of 167 published replication studies, approximately 66% were unable to confirm the original results; 12% disconfirmed at least one major result of the original study, while confirming others. In short, when exploratory research is interpreted as if it were confirmatory research, there can be no legitimate statistically significant result. As he points out, the increasing administrative responsibilities imposed on scientists is an ethical issue, in and of itself, because it impairs a scientist's ability to devote his or her energies to the practice of science. What appears to be the good of species and ecosystems often is only a by-product, average, or aggregate of that of individual organisms (and some collectives, such as ant colonies or bee hives). . Here are five things to consider. After more than one year of painstaking work to align protocols among the labs, the variability decreased. This is the conception of intrinsic value that Soul appeals to in his normative postulate: "Species have value in themselves, a value neither conferred nor revocable, but springing from a species' long evolutionary heritage and potential" (Soule 1985). (link). Interest in both reproducibility and replicability as well as misconduct was spurred by some of the same trends and a small number of widely publicized cases in which discovery of fabricated or falsified data was delayed, and the practices of journals, research institutions, and individual labs were implicated in enabling such delays (National Academies of Sciences, Engineering, and Medicine, 2017; Levelt Committee et al., 2012). In most cases, the science establishment scorns the scientist who chooses to announce his or her findings via public media before they have been published in a peer- reviewed journal. When faced with certain decisions, you can refer back to core values to ensure that you act according to what truly matters to you. On this subjective intrinsic value view, something has intrinsic value if it is valued for what it is, rather than for what it can bring about. In others, decisions made by a researcher or researchers in study execution that reasonably differ from the original study such as judgment calls on data cleaning or selection of parameter values within a model may also result in non-replication. The mean effect sizes were halved. One reason for doing this is the practical result discovered by the teachers who attended our Summer Institutes: it heightens the interest of their students because of the "humanizing" effect of incorporating ethics into science teaching. (2018, p. 14): For studies reporting statistically significant results, we treated as successful replications for which the replication 95 percent CI [confidence interval] was not lower than the original effect size. The only reason they went is that mom and dad made them go. At the institutional level of the department, laboratory or research institute, Rescher mentions the issue of support for pure, or basic, versus applied, or practical, research. Concerns about reproducibility and replicability have been expressed in both scientific and popular media. As mentioned earlier, a wider analysis of all retractions of scientific papers found about one-half attributable to misconduct or fraud (Brainard, 2018). As discussed by Rescher, there is good reason to be concerned about premature publicity about findings that have not been accepted as valid by the scientific community. Show this book's table of contents, where you can jump to any chapter by name. The committee agrees with those who argue that the testing of assumptions and the characterization of the components of a study are as important to report as are the ultimate results of the study (Plant and Hanisch, 2018) including studies using statistical inference and reporting p-values (Boos and Stefanski, 2011). Chapter 1 of Michael Pritchard and Theodore Goldfarb's instructor guide, "Ethics in the Science Classroom.". More generally, independent investigators may replicate prior results of others before conducting, or in the course of conducting, a study to extend the original work. A fundamental principle of hypothesis testing is that the same data that were used to generate a hypothesis cannot be used to test that hypothesis (de Groot, 2014). Asymmetry in the plotted values can reveal the absence of studies with small effect sizes, especially in studies with small sample sizesa pattern that could suggest publication/selection bias for statistically significant effects (see Figure 5-3). When uncertainties are unknown and not accounted for, this can also lead to non-replicability. One theme of Fostering Integrity in Research is that research misconduct and detrimental research practices are a continuum of behaviors (National Academies of Sciences, Engineering, and Medicine, 2017). Something's instrumental value fluctuates based on changes in the desirability of the end to which it is a means and whether alternative, more efficient, means are available. This allows future researchers, if they wish, to attempt replication as close to the original conditions as possible. An attempt by a second researcher to replicate a previous study is an effort to determine whether applying the same methods to the same scientific question produces similar results. 17 different labs attempted to replicate one study on facial feedback by, None of the studies replicated the result at, Pointed out that all of the studies in the, The original study was replicated when the original procedure was followed (. Soul, M. E. What is conservation biology? 87% of the replication attempts were statistically significant in the expected direction, and effects were typically 77% as strong as the corresponding original effects. Core values are the guiding principles that define your identity and your choices. NOS might be defined as "the values and assumptions inherent to science" (Lederman, 1992, p. 331). MyNAP members SAVE 10% off online. Too often in the history of science, scientists, particularly those who are young and not yet well-established, have found it very difficult to gain acceptance for revolutionary discoveries that do not fit within the prevailing disciplinary paradigm. methods of assessing replicability are inconsistent and the replicability percentages depend strongly on the methods used. Nonanthropocentrism is the view that at least some non-human interests need to be taken into account as well. Acknowledging the different approaches to assessing replicability across scientific disciplines, however, we emphasize eight core characteristics and principles: 2Cova et al. General Biology, Preclinical Animal Studies (, Attempt by researchers from Bayer HealthCare to validate data on potential drug targets obtained in 67 projects by copying models exactly or by adapting them to internal needs. 2016).The authors contend that an "unhelpful dichotomy" exists among conservationists over whether nature should be protected for humans' sake (instrumental values) or for . Sterba, J. On the contrary, when students are taught that scientists are mere mortals who are subject to the same social pressures and temptations, in their work as well as in their private lives, that influence all human endeavor, they are more likely to identify with scientists. CONCLUSION 5-3: Because many scientists routinely conduct replication tests as part of a follow-on work and do not report replication results separately, the evidence base of non-replicability across all science and engineering research is incomplete. Quadrant D includes studies of complex social behaviors that are influenced by culture and context; for example, a study of the effects of a fathers absence on childrens ability to delay gratification revealed stronger effects among younger children (Mischel, 1961). However, a 2009 study suggests that such standardization is actually the cause of non-replicability, rather than the cure. Moreover, instrumental value is substitutable, replaceable, and compensatable. In other replication studies, teams of researchers performed multiple replication attempts on a single original result, or many-to-one comparisons (see e.g., Klein et al., 2014; Hagger et al., 2016; and Cova et al., 2018 in Table 5-1). Others believe that there has been an excessive focus on Type I errors (i.e., false positives) in hypothesis testing at the possible expense of an increase in Type II errors (i.e., false negatives, or failing to confirm true hypotheses) (Fiedler et al., 2012; Finkel et al., 2015; LeBel et al., 2017). To do so, each individual must decide what they value most in life. Their value is not. In the case of Anil Potti at Duke University, a researcher using genomic analysis on cancer patients was later found to have falsified data. In that case, you might avoid traditional work and instead work as an entrepreneureven if this means working longer hours and having more financial uncertainty. Rescher discusses the issue of the amount of evidence a scientist must accumulate before announcing his or her findings. Overall, the number of journals that report retractions has grown from 44 journals in 1997 to 488 journals in 2016; however, the average number of retractions per journal has remained essentially flat since 1997. Scientific results were confirmed in 11% of the studies. Psychology. The authors of this study reported that environmental standardization may compromise replicability by systematically increasing the incidence of results that are idiosyncratic to study-specific environmental conditions (Richter et al., 2009). Before these researchers discovered the variation in technique, it was not known that the mixing method could affect the outcome in this experiment. The way a person acts and treats others is impacted by the individual's core values. Use the CORE value exercise to find your true north: At the end of the exercise, narrow down your 3-5 most important core values and keep them in mind as you move through life. B. Lippincott Company, 1914. Well known researchers or research institutions can use the sensationalism, which is as much a characteristic of science reporting as other types of journalism, to influence public opinion and governmental funding agencies. Attempt to replicate 21 systematically selected experimental studies in the social sciences published in. Because of these differences, one expects that studies that are conducted in the relatively more controllable systems will replicate with greater frequency than those that are in less controllable systems. Sustainability Science: Ethical Foundations and Emerging Challenges. was due to changes in the procedure. (1992b). Core values are an individual or organizations fundamental beliefs and highest priorities that drive their behavior. This content is currently under construction. Replicationespecially of surprising results or those that could have a major impactoccurs in science often without being labelled as a replication. Others develop a specific hypothesis or conjecture that they then try to verify or refute with carefully structured observations. When a study is published, some of these choices are reported in the methods section. This is particularly true in the United States and other industrialized nations, but also in the developing world. Researchers need also to report on steps that were intended to reduce uncertainties inherent in the study or differ from the original study (i.e., data cleaning decisions that resulted in a different final dataset). In some cases, non-replicability arises from the inherent characteristics of the systems under study. As a result, the attempts to date to gather input on topics related to replicability and reproducibility from larger numbers of scientists (Baker, 2016; Boulbes et al., 2018) have relied on convenience samples and other methodological choices that limit the conclusions that can be made about attitudes among the larger scientific community or even for specific subfields based on the data from such surveys.

"(8) Examples of Systematic Errors If you forget to calibrate a balance or you're off a bit in the calibration, all mass measurements will be high/low by the same amount. This issue emerged from cases where data in a paper have been challenged as being wrong and perhaps fraudulently represented. In 2003, an article reviewed previous studies of hydrogen storage values and reported new research results, which were later replicated (Broom and Hirscher, 2016). Journal article retractions in biomedicine increased from 50-60 per year in the mid-2000s, to 600-700 per year by the mid-2010s (National Library of Medicine, 2018), and this increase attracted much commentary and analysis (see, e.g., Grieneisen and Zhang, 2012). Attempt to independently replicate selected results from 100 studies in psychology. Give examples on how values inherent in science can be integrated in the teaching of Science. They aim to show that if humans have inherent worth, then so too do non-humans i.e., there is no adequate justification for taking the good or interests of humans into consideration, but not the good or interests of non-humans (Singer 1977, Taylor 1986, Sandler 2007) (Figure 3). For obvious reasons, scientists are no less interested than those in any other field of endeavor in receiving appropriate credit for their work. Therefore, even if individual wolves have a good of their own and inherent worth, Canis lupus, the species, may not (Cahen 1988, Sandler 2007). Exploratory and confirmatory research are essential parts of science, but they need to be understood and communicated as two separate types of inquiry, with two different interpretations. One example would be EPA's default assumption that all adults weigh 70 kg. Such assessments can identify data that are outliers to previous measurements and may signal the need for additional investigation to understand the discrepancy.4Table 5-1 summarizes the direct and indirect replication studies assembled by the committee. Inherent values are a relevant consideration in tenure review and discretionary consenting decisions.. Co-dominance. Philosophers might emphasize the methodological aspects of science focusing on experimentation, observation and theorizing as elements of the means by which reliable information about the natural world is gleaned through the practice of science. Whether arising from lack of knowledge, perverse incentives, sloppiness, or bias, these sources of non-replicability.
