Fixing Science: Practical Solutions for the Irreproducibility Crisis

When: February 7 and 8
Where: Independent Institute | 100 Swan Way, Oakland, California, 94621‑1428 


Many headline scientific findings in recent years have turned out to be false. They can’t be reproduced—and if you can’t reproduce a result, it isn’t science. The headlines are just the tip of the iceberg. A huge amount of ordinary scientific findings published in peer-reviewed journals don’t replicate. Something has gone terribly wrong in contemporary scientific procedures.

Scientists’ failure is called the Irreproducibility Crisis. It is the result of improper use of statistics, arbitrary research techniques, lack of accountability, political groupthink, and a scientific culture biased toward producing positive results. By some estimates, half of recent scientific research could be irreproducible.

“Fixing Science” brings together scholars from several disciplines to talk about practical ways to fix how scientists work. Panelists will suggest how research, scientists, academics, government officials, and philanthropists should reform scientific research. Special panels will describe how the irreproducibility crisis affects specific disciplines, including economics and climate science. Other panels will examine topics such as groupthink and falsifiability. Throughout, “Fixing Science” will focus on which reforms have worked so far, to help us craft and propose initiatives going forward. The conference will help advance practical solutions to the Irreproducibility Crisis by scientists, civil society, and lawmakers.

“Not Just an Academic Dispute: Irreproducibility of Scientific Evidence Renders Legal Judgments Unsafe”

Irreproducibility in science confounds the already strained capacity of legal actors to interpret scientific evidence. Historically, the law has not respected the requirements of valid scientific inference. Starting with its Daubert decision, the Supreme Court conditioned admissibility of expert testimony on reliability and validity. Federal judges are now “gatekeepers” of scientific evidence, which has improved scientific fact finding in court. The results, however, are uneven; judges are routinely misled by unreliable and invalid methods, which render legal judgments “unsafe.” I will discuss recent examples of irreproducible and irreplicable scientific studies, and their untoward effect on legal proceedings.

“Avoiding Investigator Bias: How to Make Economic Expertise Reproducible”

The first step to recognize that experts have the same motivational package has everyone else and the foresight of having one’s work examined by hostile eyes changes one’s incentives to do replicable work. Sandra Peart and I have proposed that that regulatory bodies adopt and expand the adversarial procedures employed in civil litigation as a way to make unbiased procedures incentive compatible. The paper reviews the consequences of the foresight of discovery and replication on incentives of experts. The context of democracy as a discovery procedure will be considered.

Richard K. Vedder, Distinguished Emeritus Professor of Economics, Ohio University

“The Economic Origins of the Irreproducibility Crisis”

Economic incentives induce professors to churn out scientific papers. Lucrative federal funding is tied to prior research. Highly productive professors, as measured by published research, are financially rewarded more than those whose "comparative advantage" is in teaching. Large overhead provisions on federal grants induce universities to promote grant proposals, even kicking back some overhead funds to principal investigators. Quality control and replication of research findings is, relatively speaking, neglected. Financial incentives induce scholars often to seek quantity over quality, and, most egregiously, to ignore fields of scholarly inquiry not significantly funded by the federal government.

P-Value "Reforms": Fixing Science or Threats to Replication and Falsification?” 

Mounting failures of replication give new urgency to critically appraising proposed statistical reforms. While many reforms are welcome, others are quite radical. The sources of irreplication are not mysterious: in many fields, latitude in collecting and interpreting data makes it too easy to dredge up impressive looking findings even when spurious. Paradoxically, some of the reforms intended to fix science enable rather than reveal illicit inferences due to P-hacking, multiple testing, and data-dredging. Some even preclude testing and falsifying claims altogether. Too often the statistics wars become proxy battles between competing tribal leaders, each keen to advance a method or philosophy, rather than improve scientific accountability.

“Model Falsifiability and Climate Slow Modes”

The most advanced climate models are actually modified meteorological models attempting to capture climate in meteorological terms. This seems a straightforward matter of raw computing power applied to large enough sources of current data. Some believe that models have succeeded in capturing climate in this manner. But have they? This paper outlines difficulties with this picture that derive from the finite representation of our computers, and the fundamental unavailability of future data instead. It suggests that alternative windows onto the multi-decadal timescales are necessary in order to overcome the issues raised for practical problems of prediction.

“The Irreproducibility Crisis and the Lehman Crash”

Multiple initiatives have been launched to address the replication crisis in social sciences and elsewhere. I will summarize their proposed strategies and identify some obstacles to their widespread adoption. Pre-registration is frequently regarded as a silver bullet, but I will show that pre-registration will fail so long as scientists are allowed to use their own terminology to describe the experiments they plan to perform and the data they plan to collect. I will conclude by pointing to an analogous failure in the domain of finance, and describe attempts there to avoid repetition of financial crises such as the Lehman crash.

“Reproducibility Reforms if there is no Irreproducibility Crisis”

Science is not, as a whole, in a crisis, but it is undeniably facing challenges in how research is conducted, interpreted and communicated. Some of the challenges are new, others have been known for a long time but are hard to overcome. These issues are so insidious and subtle that they affect meta-research itself. Indeed, they underlie much of the erroneous perception that there is a “reproducibility” crisis. This talk will illustrate some of these problems using examples from meta-science and the literature on reproducibility, and it will discuss possible directions of progress.

10:00 am—Climate Sciences and the Irreproducibility Crisis

Moderator: Anastasios Tsonis

Tim Edgell, Principal, Environmental Services, Stantec, Inc.

“Stylistic Bias, Selective Reporting, and Climate Science”

Is science free from bias, personal beliefs, and sensationalism? Absolutely not. Dr. Edgell investigated patterns of bias in climate change science, a field whose principal findings are described as both a hoax and the most important scientific truth of our time. Ironically, in revealing biases about how scientists write and publish about climate change, we gain confidence in the underlying science and leading theories. This talk will remind us that both scientists and the consumers of science have a responsibility to seek truth behind the headlines. After all, science is a human construct, driven by the humanistic propensity for storytelling and reinforcing beliefs.

Patrick J. Michaels, Senior Fellow, Competitive Enterprise Institute

“Biased Climate Science”

The interaction of public choice, monopolistic funding, and skewed professional incentives with the power politics of environmental policy has resulted in a demonstrably biased canon of knowledge in the domain of climate science. The only quantitative forecasting tools that its practitioners have are undergoing a systematic failure, and yet the community neither admits to the problem nor does anything substantive about it. When the resultant scientific literature is summarized in policy-relevant documents, such as IPCC reviews or U.S. “National Assessments”, if they are accurate, they will reflect a similar bias, resulting in unwise, wasteful and harmful policies.

“How to Evaluate Meta-Analyses of Environmental Epidemiology”

Well over 80% of claims made in observational studies fail to replicate. Some think meta-analysis studies using results from multiple observational studies are suitable for decision making. About 5,000 meta-analysis studies are published each year. I evaluate the reliability of meta-analyses in environmental epidemiology. I evaluate the base studies for p-hacking, trying this and that analysis to get a p-value less than 0.05. Plotting a p-value from each base study, ranked, against the integers, often shows a pattern consistent with p-hacking. I show that the base studies and the resulting meta-analysis are frequently unreliable, and have no sound statistical basis.

“Reproducibility is Essential to Combating Environmental Lysenkoism”

My 2017 independent reanalysis of the ACS Cancer Prevention Study data found no robust relationship between fine particulate matter (PM2.5) and total mortality, contrary to the seminal 1995 Pope analysis that justified the 1997 EPA PM2.5 National Ambient Air Quality Standard. My reanalysis increases the evidence that inhaling about 100 micrograms of invisible fine particles per day does not cause premature deaths. In addition, it demonstrates the importance of access to underlying data to in order to strengthen transparency and reproducibility in regulatory science. Finally, it increases efforts to combat the current form of Lysenkoism that has corrupted environmental epidemiology.

“Causality, reproducibility, and scientific generalization in public health”

Irreproducibility threatens the trustworthiness of public health risk assessments informing regulation, litigation, and public policy.  So does too-easy reproducibility of results that are untrue, irrelevant, or misleading.  Announced results can becomes anchors for subsequent modeling and confirmation biases.  If a research group announces a “link,” between an exposure and a feared health effect, others may confirm it even if exposure is not causally related to risk.  Modern causal analysis helps assure that announced results reflect genuine causal relationships, useful for policy making.  This talk describes how, and gives several examples from public health.

1:45 pm—Groupthink and the Irreproducibility Crisis

Moderator: Nathan A. Schachtman

Lee Jussim, Chair, Psychology Department, Rutgers University

“Intellectual Diversity Limits Groupthink in Scientific Psychology

Groupthink occurs when there are social pressures for all to say they think, alike.  An obvious remedy is embrace of intellectual diversity, the opposite of groupthink. Why is intellectual diversity crucial to a strong psychological science?  If science is based on facts, the need for intellectual diversity seems moot.  However, the pursuit of scientific facts is plagued by uncertainty at every turn, and intellectual diversity is crucial to resolving that uncertainty.  I highlight four separate dimensions of “intellectual diversity”: skepticism, theoretical diversity, demographic diversity, and political diversity, and show how embrace of each is likely to improve psychological science.

Mark Regnerus, Professor, Sociology Department, University of Texas at Austin

Groupthink in Sociology

The crisis in reproducibility has reached sociology, insofar as its practitioners conduct replicable forms of research. While there have been calls for greater openness and data transparency, this move is hamstrung by the wide use of proprietary data collected by scholars themselves. A larger problem which data transparency cannot solve, however, is the disregard for creative theory-building in sociology, as well as the longstanding disinterest in studying processes in favor of documenting inequalities. Unlike replicability concerns, these latter challenges are rooted in a tendency toward groupthink and the application of political ideals—such as justice, liberation, and diversity—to research methods.

“Giving the Devil His Due”

Who is the devil and what is he due? The devil is anyone who disagrees with you or someone else, and what he is due is the right to speak his mind. He must have this for your own safety’s sake, because his freedom is inextricably tied to your own. If he can be censored, why shouldn’t you be censored? If we put barriers up to silence “unpleasant” ideas, what’s to stop the silencing of any discussion? This talk is a full-throated defense of free speech, open inquiry, and heterodox thinking in politics, science, and culture. “Hate speech” and “dangerous ideas” should never be censored; instead, we should counter hate speech with free speech, dangerous ideas with truthful ideas, and alternative facts with real facts.

“Helping Science Recover: A Business Approach”

The irreproducibility crisis is a symptom of the malaise that is also manifested by the slowing stream of new drugs, the expansion of administration, neglected basic research, the lost sense of purpose and motivation, the flight of talent, and a numbing hypercompetition. I would like to suggest that this malaise results from a synergy of two causes: adopting a conceptual foundation that clashes with the nature of scientific discovery and the motivation of creative individuals, and an exponential increase in the information generated by scientific research. I am going to discuss how our company, Scite, Inc., helps to solve these problems.

David Trafimow, Professor, Psychology Department, New Mexico State University

“What Journals Can Do To Fix The Irreproducibility Crisis”

A successful replication is typically characterized by a statistically significant finding in the original study, and in the replication study, in the same direction. However, because significance testing is invalid, this characterization of a successful replication is similarly invalid. Journals should use a different conceptualization, whereby a successful replication entails a strong probability that the sample statistics of interest are close to their corresponding population parameters, in both original and replication studies. The a priori procedure enables researchers to use this alternative conceptualization, and journal editors could insist on it.

David Randall, Director of Research, National Association of Scholars

“Regulatory Science and the Irreproducibility Crisis”

Regulatory science is distinct from research science, and should not be held to identically strict standards. Nevertheless, the irreproducibility crisis suggests that we must also reform how the federal government funds science and uses science. Precisely because government can no longer use statistical significance as a “master protocol” to justify regulations, government should require 1) fully reproducible scientific procedures and data; and 2) new limits and transparency on scientific experts’ discretionary expertise. Government should also generously fund anonymization and replication of key data sets, to ensure regulatory continuity and consensus support from the scientific community for these regulatory reforms.

“What Professional Organizations Can Do To Fix The Irreproducibility Crisis”

In 2016, the ASA took the extraordinary step of producing a statement on p-values and statistical significance. This was way outside its normal activities. Wasserstein will briefly discuss why ASA did this, how it was accomplished, and what the effects of the statement have been. He will talk frankly about how difficult this was to do, and what it takes to get a job like this done, but also share why he thinks it is important for professional associations to take up issues like this when it is the right time to do so.
