Chapter 1 Conducting reproducible, transparent, and credible research

Policy decisions are made every day using the results of development research, and these have wide-reaching effects on the lives of millions. As the emphasis on evidence-based policy grows, so too does the scrutiny under which research methods and results are placed. Three major components make up this scrutiny: credibility, transparency, and reproducibility. These three components contribute to one simple idea: research should be high quality and well-documented. Research consumers, including the policy makers who will use the evidence to make decisions, should be able to easily examine and recreate such evidence. In this framework, it is useful to think of research as a public service that requires researchers as a group to be accountable for their methods. This means acting to collectively protect the credibility of development research by following modern practices for research planning and documentation. Across the social sciences, the open science movement has been fueled by concerns about the proliferation of low-quality research practices, data and code that are inaccessible to the public, analytical errors in major research papers, and in some cases even outright fraud. While the development research community has not yet experienced major scandals, it has become clear that there are necessary improvements to make in the way that code and data are handled as part of research. Moreover, having common standards and practices for creating and sharing materials, code, and data with others will improve the value of the work we do.

In this chapter, we outline principles and practices that help to ensure research consumers can be confident in the conclusions reached. We discuss each of the three components – credibility, transparency, and reproducibility – in turn. The first section covers research credibility. It presents three popular methods to commit to particular research questions or methods, and avoid potential criticisms of cherry-picking results: registration, pre-analysis plans, and registered reports. The second section discusses how to apply principles of transparency to all research processes, which allows research teams to be more efficient, and research consumers to fully understand and evaluate research quality. The final section provides guidance on how to make your research fully reproducible, and explains why publishing replication materials is an important research contribution in its own right.

Summary: Conducting reproducible, transparent, and credible research

This chapter describes three pillars of a high-quality empirical research project: credibility, transparency and reproducibility. These steps and outputs discussed in this chapter should be prepared at the beginning of a project and revisited through the publication process.

1. Credibility: to enhance credibility, you should pre-commit research decisions as much as feasible

  • Register research studies to provide a record of every project, so all evidence about a topic can be maintained; pre-register studies to protect design choices from later criticism.
  • Write pre-analysis plans to both strengthen the conclusions drawn from those analyses and increase efficiency by creating a road map for project data work.
  • Publish a registered report to combine the benefits of the two steps above with a formal peer review process and a conditional acceptance of the final results of the specified research.

2. Transparency: you should document all data acquisition and analysis decisions during the project lifecycle, with a clear understanding of what will be released publicly and plan for how those will be published

  • Develop and publish comprehensive project documentation, especially instruments for data collection or acquisition that may be needed to prove ownership rights and facilitate re-use of the data.
  • Retain all original data in an unaltered form and archive it appropriately, in preparation for it to be de-identified and published at the appropriate time.
  • Write all data processing and analysis code with public release in mind.

3. Reproducibility: Prepare analytical work that can be verified and reproduced by others. This means

  • Understanding what archives and repositories are appropriate for your various materials
  • Preparing for legal documentation and licensing of data, code, and research products
  • Initiating reproducible workflows that will easily transfer within and outside of your research team and the necessary documentation for others to understand and use your materials

Takeaways

TTLs/PIs will:

  • Develop and document the research design and the corresponding data required to execute it
  • Guide the research team in structuring and completing project registration
  • Understand the team’s future rights and responsibilities regarding data, code, and research publication
  • Determine what methods of pre-commitment are appropriate and lead the team in preparing them

RAs will:

  • Rework outputs and documentation to meet specific technical requirements of registries, funders, publishers, or other governing bodies
  • Inform the team leadership whenever methodologies, data strategies, or their planned executions are not sufficiently clear or are not appropriately documented or communicated
  • Familiarize themselves with best practices for carrying out reproducible and transparent research, and initiate those practices within the research team

Key Resources

Developing a credible research project

The evidentiary value of research is traditionally a function of design choices,16 such as powered through sampling and randomization, and robustness to alternative specifications and definitions. One frequent target for critics of such research17 is the fact that most researchers have a lot of leeway in selecting their projects, results, or outcomes after already having had the experience of implementing a project or collecting data in the field, which increases the likelihood of finding “false positive” results that are not true outside carefully-selected data.18 Credible research design methods are key to maintaining credibility in these choices and avoiding serious errors. This is especially relevant for research that relies on original data sources, from innovative big data sources to unique surveys. Development researchers should take these concerns seriously. Such flexibility can be a significant issue for the quality of evidence overall, particularly if researchers believe that certain types of results are substantially better for their careers or their publication chances.

This section presents three popular methods for researchers to commit to particular research questions or methods, and to avoid potential criticisms of cherry-picking results for publication: registration, pre-analysis plans, and registered reports. Each of these methods involves documenting specific research design components, ideally before carrying out the analytical component or extensively exploring the data. Study registration provides formal notice that a study is being attempted and creates a hub for materials and updates about the study results. Pre-analysis plans are a more formal commitment to use specific methods on particular questions. Writing and releasing a pre-analysis plan in advance of working with data is used to protect the credibility of approaches that have a high likelihood of producing false results.19 Finally, registered reports allow researchers to approach research planning itself as a process at the level of a full peer review. Registered reports enable close scrutiny of a research design, a feedback and improvement process, and a commitment from a publisher to publish the study based on the credibility of the design, rather than the specific results.

Registering research studies

Registration of research studies is an increasingly common practice, and more journals are beginning to require the registration of studies they publish.20 Study registration intended to ensure that a complete record of research inquiry is easily available.21 Registering research studies ensures that future scholars can quickly find out what work has been carried out on a given question, even if some or all of the work done never results in formal publication. Registration of studies is increasingly required by publishers and can be done before, during, or after the study with essential information about the study purpose. Some currently popular registries are operated by the AEA,22 3ie,23 eGAP,24 and OSF25. They all have different target audiences and features, so select one that is appropriate to your work. Study registration should be feasible for all projects, as registries are typically free to access and can be initially submitted with minimal information about the project. A generally-acceptable practice will be to gradually revise and expand the level of detail in a registration over time, adding more information as the planning for the project progresses.

Pre-registering studies before they begin is an extension of this principle.26 Registration of a study before it goes to implementation or data acquisition, particularly when specific hypotheses are included in the registration, provides a simple and low-effort way for researchers to conclusively demonstrate that a particular line of inquiry was not generated by the process of data collection or analysis itself.27 Pre-registrations need not provide exhaustive details about how a particular hypothesis will be approached; only that it will be. Pre-registering specific individual elements of research design or analysis can be highly valuable for the credibility of the research and requires only minor time investment or administrative effort. For this reason, the DIME team requires pre-registration of all studies in a public database with at least some primary hypotheses prespecified, prior to providing funding for impact evaluation research.

Demand for Safe Spaces Case Study: Registering Research Studies

The experimental component of the Demand for Safe Spaces study was registered at the Registry for International Development Impact Evaluations (RIDIE) under ID 5a125fecae423.

Highlights from the Registry:

  • Indicated evaluation method: both primary method (randomized control trial) and additional methods (difference-in-difference/fixed effects).
  • Listed key outcome variables: take-up of rides in women-only car (binary), occurrence of harassment or crime during ride (binary), self-reported well-being after each ride, overall subjective well-being, Implicit Association Test D-Score.
  • Specified primary hypotheses to be tested: The women-only car reduces harassment experienced by women who ride it; Riding the women’s-only car improves psychological well-being of those who ride it; Women are willing to forego income to ride the women’s-only car.
  • Specified secondary research question and methods: supplementary research methods (implicit association test and platform survey) to help address an additional hypothesis: The women’s-only car is associated with a social norm that assigns responsibility to women for avoiding harassment.
  • Provided sample size for each study arm: number of individual participants, number of baseline rides, number of rides during price experiment, number of car-assigned rides, number of expected participants in implicit association test.
  • Described data sources: the study relied on data previously collected (through the mobile app) and data to-be-collected (through platform surveys and implicit association tests).
  • Registration status: categorized as a non-prospective registry, as the crowdsourced data had already been received and processed. It was important to the team to ensure the credibility of additional data collection and secondary research questions by registering the study.

Writing pre-analysis plans

If a research team has a large amount of flexibility to define how they approach a particular hypothesis, study registration may not be sufficient to avoid the criticism of “hypothesizing after the results are known”, or HARKing.28 Examples of such flexibility include a broad range of concrete measures that could be argued to measure to an abstract concept; future choices about sample inclusion or exclusion; or decisions about how to construct derived indicators. There are a variety of templates and checklists of details to include.29 When the researcher is collecting a large amount of information and has leverage over even a moderate number of these options, it is almost guaranteed that they can come up with any result they like.30

Pre-analysis plans (PAPs) can be used to assuage these concerns by specifying some set of analyses the researchers intend to conduct.31 The pre-analysis plan should be written up in detail for areas that are known to provide a large amount of leeway for researchers to make later decisions, particularly for things like interaction effects or subgroup analysis.32 Pre-analysis plans shoud not, however, be viewed as binding the researcher’s hands.33 Depending on what is known about the study at the time of writing, pre-analysis plans can vary widely in the amount of detail they should include.34 The core function of a PAP is to carefully and explicitly describe one or more specific data-driven inquiries, as specific formulations are often very hard to justify in retrospect with data or projects that potentially provide many avenues to approach a single theoretical question.35 Anything outside the original plan is just as interesting and valuable as it would have been if the plan was never published; but having pre-committed to the details of a particular inquiry makes its results immune to a wide range of criticisms of specification searching or multiple testing.36

Demand for Safe Spaces Case Study: Writing Pre-Analysis Plans

Although the Demand for Safe Spaces study did not publish a formal pre-analysis plan, the team published a concept note in 2015, which includes much of the same information as a typical pre-analysis plan. The Concept Note was updated in May 2017 to include new secondary research questions. The Concept Note, prepared before fieldwork began, was subject to review and approval within the World Bank and from a technical committee including blinded feedback from external academics. The Concept Note specified the planned study along the following dimensions:

  • Theory of change: the main elements of the intervention, and the hypothesized causal chain from inputs, through activities and outputs, to outcomes.
  • Hypotheses derived from the theory of change
  • Main evaluation question(s) to be addressed by the study
  • List of main outcomes of interest, including outcome name, definition, level of measurement
  • Evaluation design, including a precise description of the identification strategy for each research questions and description of treatment and control groups
  • Sampling strategy and sample size calculation, detailing the assumptions made
  • Description of all quantitative data collection instruments
  • Data processing and analysis: the statistical methods to be used, the exact specification(s) to be run, including clustering of standard errors; key groups for heterogeneity analysis; adjustments for multiple hypothesis testing; strategy to test (and correct) for bias.

A version of the study’s Concept Note is available at https://github.com/worldbank/rio-safe-space/blob/master/Online%20Appendices/Supplemental%20Material/Project%20Concept%20Note.pdf

Publishing registered reports

Registered reports take the process of pre-specifying a complex research design to the level of a formal publication.37 In a registered report, a journal or other publisher will peer review and conditionally accept a specific study for publication, typically then guaranteeing the acceptance of a later publication that carries out the analysis described in the registered report. While far stricter and more complex to carry out than ordinary study registration or pre-analysis planning, the registered report has the added benefit of peer review and expert feedback on the design and structure of the proposed study.38 Registered reports are never required, but they are designed to reward researchers who are able to provide a large amount of advance detail for their projects, researchers who want to secure publication interest regardless of results, or researchers who want to use methods that may be novel or unusual.

This process is in part meant to combat the “file-drawer problem”39 and ensure that researchers are transparent in the sense that all promised results obtained from registered-report studies are actually published. This approach has the advantage of pre-specifying in great detail a complete research and analytical design, and securing a commitment for publication regardless of the outcome. This may be of special interest for researchers studying events or programs where either there is a substantial risk that they would either not be able to publish a null or negative result,40 or where they may wish to avoid any pressure toward finding a particular result, for example when the program or event is the subject of substantial social or political pressures. As with pre-registration and pre-analysis, nothing in a registered report should be understood to prevent a researcher from pursuing additional avenues of inquiry once the study is complete, either in the same or separate research outputs.

Conducting research transparently

Transparent research exposes not only the code, but all research processes involved in developing the analytical approach. This means that readers are able to judge for themselves whether the research was done well and the decision-making process was sound. If the research is well-structured, and all of the relevant documentation41 is shared, it is easy for the reader to understand the analysis fully. Researchers that expect process transparency also have an incentive to make better decisions, be skeptical and thorough about their assumptions, and save themselves time, because transparent research methods are labor-saving over the complete course of a project.

Clearly documenting research work is necessary to allow others to evaluate exactly what data was acquired and how it was used to obtain a particular result. Many development research projects are purpose-built to address specific questions, and often use unique data, novel methods, or small samples. These approaches can yield new insights into essential academic questions, but need to be transparently documented so they can be reviewed or replicated by others in the future.42 Unlike disciplines where data is more standardized or where research is more oriented around secondary data, the exact data used in a development project has often not been observed by anyone else in the past and may not be able to be re-collected by others in the future. Regardless of the novelty of study data, transparent documentation methods help ensure that data was collected and handled appropriately and that studies and interventions were implemented correctly. As with study registrations, project and data documentation should be released on external archival repositories43 so they can always be accessed and verified.

Documenting data acquisition and analysis

Documenting a project in detail greatly increases transparency. Many disciplines have a tradition of keeping a “lab notebook”, and adapting and expanding this process to create a lab-style workflow in the development field is a critical step towards more transparent practices. This means explicitly noting decisions as they are made, and explaining the process behind the decision-making. Careful documentation will also save the research team a lot of time during a project, as it prevents you from having the same discussion twice (or more!), since you have a record of why something was done in a particular way. There are a number of available tools that will contribute to producing documentation, but project documentation should always be an active and ongoing process, not a one-time requirement or retrospective task. New decisions are always being made as the plan begins contact with reality, and there is nothing wrong with sensible adaptation so long as it is recorded and disclosed.

Email, however, is not a documentation service, because communications are rarely well-ordered, can be easily deleted, and are not available for future team members. At the very least, emails and other decision-making communications need to be archived and preserved (as, say, PDFs) in an organized manner so that they can be easily accessed and read by others in the future. There are also various software solutions for building proper documentation over time. Some work better for field records such as implementation decisions, research design, and survey development; others work better for recording data work and code development. The Open Science Framework44 provides one such solution, with integrated file storage, version histories, and collaborative wiki pages. GitHub45 provides a transparent documentation system through commit messages, issues, README files, and pull requests,46 in addition to version histories and wiki pages. Such services offer multiple different ways to record the decision process leading to changes and additions, track and register discussions, and manage tasks. These are flexible tools that can be adapted to different team and project dynamics. Services that log your research process can show things like modifications made in response to referee comments, by having tagged version histories at each major revision. They also allow you to use issue trackers to document the research paths and questions you may have tried to answer as a resource to others who have similar questions. Each project has specific requirements for data, code, and documentation management, and the exact transparency tools to use will depend on the team’s needs, but they should be agreed upon prior to project launch. This way, you can start building a project’s documentation as soon as you start making decisions.

Cataloging and archiving data

Data and data collection methods should be fully cataloged, archived, and documented, whether you are collecting data yourself or receiving it from an outside partner. In some cases this is as simple as uploading a survey instrument or an index of datasets and a codebook to an archive. In other cases this will be more complex. Proper documentation of data collection will often require a detailed description of the overall sampling procedure.47 For example, settings with many overlapping strata, treatment arms, excluded observations, or resampling protocols might require extensive additional field work documentation. This documentation should be continuously updated and kept with the other study materials; it is often necessary to collate these materials for an appendix for publication in any case.

When data is received from partners or collected in the field, the original data (including corrections)48 should be immediately placed in a secure permanent storage system. Before analytical work begins, you should create a “for-publication” copy of the acquired dataset by removing potentially identifying information. This will become the original data, and must be placed in an archival repository where it can be cited.49 This can initially be done under embargo or with limited release, in order to protect your data and future work. This type of data depositing or archiving precedes publishing or releasing any data: data at this stage may still need to be embargoed or have other, potentially permanent, access restrictions, so you can instruct the archive to formally release the data later. If your planned analysis requires the use of unpublishable data, that data should always remain encrypted and be stored separately so it is clear what portions of the code will work with and without obtaining a license to the needed restricted-access data.

Some project funders provide specific repositories in which they require the deposit of data they funded,50 and you should take advantage of these when possible. If this is not provided, you must be aware of privacy issues with directly identifying data and questions of data ownership before uploading original data to any third-party server, whether public or not; this is a legal question for your home organization. If data that is required for analysis must be placed under restricted use or restricted access, including data that can never be distributed directly by you to third parties, develop a plan for storing that data separately from publishable information. This will allow you to maximize transparency by having a clear release package as well as providing instructions or developing a protocol for allowing access in the future for replicators or reviewers under appropriate access agreements.51 Regardless of these consideration, all data repositories, such as DIME’s standard, the World Bank Microdata Library52 and the World Bank Data Catalog,53 should create a record of the data’s existence and provide instructions on how access might be obtained by another researcher. For more on the steps required to prepare and publish a de-identified dataset, you can refer to chapters 6 and 7 of this book. Data publication should create a data citation and a digital object identifier (DOI),54 or some other persistent index that you can use in your future work to unambiguously indicate the location of your data. This data publication should also include the methodological documentation as well as complete human-readable codebooks for all the variables there.

Analyzing data reproducibly

Reproducible research makes it easy for others to apply your techniques to new data or to implement a similar research design in a different context. Development research is rapidly moving in the direction of requiring adherence to specific reproducibility guidelines.55 Major publishers and funders, most notably the American Economic Association, have taken steps to require that code and data are accurately reported, cited, and preserved as research outputs that can be accessed and verified by others. Making research reproducible in this way is a public good.56 It enables other researchers to re-use code and processes to do their own work more easily and effectively in the future. Regardless of what is formally required, your code should be written neatly with clear instructions. It should be easy to read and understand. The corresponding analysis data should also be made accessible to the greatest legal and ethical extent that it can be.57

Common research standards from journals and funders feature both regulation and verification policies.58 Regulation policies require that authors provide reproducibility packages before publication which are then reviewed by the journal for completeness.59 Verification policies require that authors make certain materials available to the public, but their completeness is not a precondition for publication. Other journals have adopted guidance that offer checklists for reporting on whether and how various practices were implemented, without specifically requiring any.60 If you are personally or professionally motivated by citations, producing these kinds of resources can lead to that as well. Even if privacy considerations mean you will not be publishing some or all data or results, these practices are still valuable for project organization.

Our recommendation, regardless of external requirements, is that your should prepare to release all data that can be published When data cannot be published, you should try to publish as much metadata as allowed, including information on how the data was obtained, what fields the data contains and aggregations or descriptive statistics. Even if the data cannot be published, it is rare for code files to contain restricted information, so the code should still be made available with clear instructions for obtaining usable data. Additionally, we recommend that reproducibility efforts be considered when designing the IRB and data licensing agreement for sensitive data, to establish acceptable conditions (such as a secure transfer or cold room) under which representatives from journals or other academics could access data may access the data for the purpose of independently reproducing results.

Preparing a reproducibility package

At DIME, all research outputs are required to satisfy computational reproducibility,61 which is an increasingly common requirement for publication.62 Before releasing a working paper, the research team submits a reproducibility package with de-identified data, and DIME Analytics verifies that the package produces exactly the same results that appear in the paper.63 The team also comments on whether the package includes sufficient documentation. The Analytics team organizes frequent peer code review for works in progress, and our general recommendation is to ensure that projects are always externally reproducible instead of waiting until the final stages to prepare this material. Once the computational reproducibility check is complete, the team receives a completed reproducibility certificate that also lists any publicly available materials to accompany the package, for use as an appendix to the publication. The team also organizes regular peer code review for works in progress, and our general recommendation is to ensure that projects are always externally reproducible instead of waiting until the final stages to prepare this material. In this way, code is continuously maintained with clear documentation, and should be easy to read and understand in terms of structure, style, and syntax.

For research to be reproducible, all code files for data cleaning, construction and analysis should be public, unless they contain confidential information. Nobody should have to guess what exactly comprises a given index, or what controls are included in your main regression, or whether or not you clustered standard errors correctly. That is, as a purely technical matter, nobody should have to “just trust you”, nor should they have to bother you to find out what would happen if any or all of these things were to be done slightly differently.64 Letting people play around with your data and code is a great way to have new questions asked and answered based on the valuable work you have already done.65

A reproducibility package should include the complete materials needed to exactly re-create your final analysis, and be accessible and well-documented so that others can identify and adjust potential decision points that they are interested in. They should be able to easily identify: what data was used and how that data can be accessed; what code generates each table, figure and in-text number; how key outcomes are constructed; and how all project results can be reproduced. This is important to plan ahead for, so that you can make sure you obtain the proper documentations and permissions for all data, code, and materials you use throughout the project. A well-organized reproducibility package usually takes the form of a complete directory structure, including documentation and a master script, that leads the reader through the process and rationale for the code behind each of the outputs when considered in combination with the corresponding publication.

Demand for Safe Spaces Case Study: Preparing a Reproducibility Package

The Demand for Safe Spaces team published all final study materials to a repository on the World Bank’s GitHub account. The repository holds the abstract of the paper, ungated access to the most recent version of the full paper, an online appendix including robustness checks and supplemental material, and the project’s reproducibility package.

The data for this project is published in the Microdata Catalog, under the survey ID number BRA_2015-2016_DSS_v01_M. The Microdata catalog entry includes metadata on the study, documentation such as survey instruments and technical reports, terms of use for the data, and access to downloadable data files. Both the crowdsourced data and the platform survey data are accessible through the Microdata Catalog.

The “Reproducibility Package” folder on GitHub contains all the instructions for executing the code. Among other things, it provides licensing information for the materials, software and hardware requirements including time needed to run, and instructions for replicators (which are included below). Finally, it has a detailed list of the code files that will run, their data inputs, and the outputs of each process.

Looking ahead

With the ongoing rise of empirical research and increased public scrutiny of scientific evidence, making analysis code and data available is necessary but not sufficient to guarantee that findings will be credible. Even if your methods are highly precise, your evidence is only as good as your data – and there are plenty of mistakes that can be made between establishing a design and generating final results that would compromise its conclusions. That is why transparency is key for research credibility. It allows other researchers, and research consumers, to verify the steps to a conclusion by themselves, and decide whether their standards for accepting a finding as evidence are met. Every investment you make in documentation and transparency up front protects your project down the line, particularly as these standards continue to tighten. With these principles in mind, the approach we take to the development, structure, and documentation of data work provides a system to implementing these ideas in everyday work. In the next chapter, we will discuss the workspace you need in order to work reproducibly in an efficient, organized, and secure manner.
