Are most published research findings false? Trends in statistical power, publication bias and p-hacking as well as the false discovery rate in psychology (1975–2017)

PLOS ONE

Dear Dr. Schneck,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

First of all I would like to thank the two reviewers of this manuscript. They did a fast a very comprehensive peer review. I found it all the more informative.

As far as I can tell, there are major concerns with the methods used in this manuscript, as suggested by reviewer 2. I cannot guarantee acceptance at this step but I will be happy to read a new edited version of the manuscript with all the appropriate responses. I expect sound responses before making a decision. Please fix any issue that can be fixed and please make sure you explain very carefully all your limitations in the paper (and also in the abstract (to avoid any spin)). Please also consider fixing the potential errors with the R code. Again, there is no guarantee that the edited version of the manuscript will be accepted after resubmission as there are many concerns but I would be happy to read an improved version of the paper.   

Please submit your revised manuscript by Apr 29 2021 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: http://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols

We look forward to receiving your revised manuscript.

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

Reviewer #1: Partly

Reviewer #2: Partly

**********

2. Has the statistical analysis been performed appropriately and rigorously?

Reviewer #1: Yes

Reviewer #2: I Don't Know

**********

3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

Reviewer #2: Yes

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: My complete review file is uploaded as an attachment.

This manuscript analyzes 650,000 test statistics from 40,000 published psychology articles over almost 40 years to provide an estimation of statistical power, publication bias and p-hacking, and the false discovery rate across the field. To briefly summarize the results, the statistical power was low, but shows a (small) increase over time. There is an excess of statistically significant results, and the false discovery rate across the field is around 32%.

Overall, I think this article does a good job of conveying the issue of an excess of statistically significant results in the psychology field. It is particularly worrisome that so many reported results are statistically significant, and that the statistical power has increased so little over the past few years. The introduction of the article is accessible, gives a clear introduction to topics like publication bias, and provides a comprehensive overview of how these issues relate to problematic consequences within science. I checked out the supplemental materials associated with this manuscript. I did not try to reproduce all results, but it is relatively easy to load in data and to extract specific information from the script. I also appreciate the use of a README file to indicate which files direct me to which results.

This manuscript can benefit from more clarification on certain points to better convey its message. In short, I think the “p-hacking” element of the study deserves more nuance, some robustness checks and other methodological choices could be added, and I believe a redistribution of the information conveyed in the manuscript and supplemental material is warranted. Improving these points can help better facilitate the use of the considerable amount of results, and help readers better assess the methods and results in the study.

I have constructed the remainder of this review into four sections: p-hacking, other methodology, supplemental material, and minor remarks. The numbers at the beginning of each point refer to line numbers in the manuscript. Please feel free to contact me for clarifications.

Signed,

Esther Maassen

My complete review file is uploaded as an attachment.

Reviewer #2: As comments exceed the 20000 characters limit, they are attached as a DOCX file.

Please, find below the introduction of my review:

The author shows a large-scale epidemiological review of the literature in psychology and sociology from APA PsycArticles®, a set of 221,554 articles in 119 peer-reviewed journals. The supporting material is extensive, with R scripts, the study database and a large appendix with supplementary tables and figures. Many robustness analyses and simulations have been performed to assess the impact of hypotheses and chose the best models. The subject is relevant in the reproducibility crisis of science.

However, there are serious limitations inherent to the design of the study; some of them cannot be easily fixed. At least, the limitations should be discussed. Some results may have to be changed or removed. The editor should consider the limitations in his acceptation or refusal of the manuscript.

In addition, there are many minor problems with the actual structure of the manuscript that can be fixed easily: better reporting of Methods, with less reliance to Supplementary Information, a structured Discussion, including a paragraph about strengths and limitations, a comparison to the literature and research perspectives. The editorial entitled “The case for structuring the discussion of scientific papers” (BMJ 1999;318:1224) may help the author.

Revision 1

Dear Esther Maassen, dear Dr. André Gillibert,

Many thanks for your constructive and very helpful comments that I hope improved the paper substantially. Besides the changes reported below, the manuscript was, as suggested, entirely rewritten to assure better readability and at the same time convey more methodological details in the main text.

In the response.docx file you can find my point by point replies to each of your remarks. The reply text is highlighted in red. Passages that were added in the manuscript and addressed the related issue were highlighted in green.

I hope that the manuscript is now suitable for publication in PLOS ONE.

Again many thanks for your remarks and best wishes

Andreas Schneck

Dear Dr. Schneck,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

First of all I would like to thank André Gillibert for his very useful and important input on this manuscript. I read the comments and really think that those are valuable and helpful. I also measure the workload required by this new round of revisions. In addition, I really think that we are getting closer to a manuscript closer to acceptance. I'm looking forward to reading a new version of the manuscript with detailed answers to the reviewer's comment. Please pay addition to make sure that the main limitations are very clear both in the abstract and in the conclusion of the paper. It is quite rare to have such an in depth review of a manuscript before publication and I applaud this detailed review because I really think that the manuscript is improving at each step. As an author (as part of PLOS One policy : https://journals.plos.org/plosone/s/editorial-and-peer-review-process), you will be asked to make the peer review history public (open peer review). I strongly support this approach -especially for this manuscript- and I definitively hope that you will opt for this. 

Please submit your revised manuscript by Jun 23 2022 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org.

Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

First of all, I would like to thank the reviewer for his comments. He kindly ask me for a delay in reviewing the paper because of workload and I agreed so any inconvenience in terms of delays is on my own responsibility. Indeed, his comments seems very important to me. I now think that we are getting closer to acceptance. The few remaining comments don't look very difficult to address but remain quite important. As the reviewer suggests, I consider that because the numerical results may somewhat change, this is a major revision. But please be sure that I really consider this manuscript as an important one and that I am really looking forward to considering your revised paper. 

Please submit your revised manuscript by Jan 26 2023 11:59PM.

Sorry for this late response. I was quite busy lately.

Thank you for the extensive work you performed to answer to my comments.

Almost all problems in the previous manuscript are fixed. The few remaining problems should not be hard to fix. Although my reviewing is lengthy, I think that the issues it rises are not that that big.

There may be a few substantial modifications that may change some results. This is why I consider that there is a “major revision” although it is less major than previous ones.

6. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #2: The manuscript has been improved and is now quite good in my opinion. The objective, methods, results and discussion are consistent. Limitations are well acknowledged.

I do not have major comments but have many minor comments and suggestions, spotting stylistic issues and minor errors.

Maybe the worst issue lies in probable errors of equations shown in the Appendix. I hope that these equations were not used for computations.

I would like to thank the author for the great patience he had, to resubmit repeatedly his manuscript, responding to all my comments for several rounds.

Please, find all comments in the Attachment!

Revision 5

Dear Prof. Florian Naudet, dear Dr. André Gillibert,

Again, thank you both for your very helpful and inspiring comments. I hope that I addressed the remaining issues. For a detailed response to each remark, see the response to reviewers.

Besides the smaller edits, I rechecked the code and found a small error in estimating the p-hacking rate. As a result, the p-hacking rate was slightly lower (8.8% instead of 9.9% for the main p-hacking scenario). The text was also edited by a native English-speaking proofreader.

I hope the manuscript is now suitable for publication in PLOS ONE, and thank you for all your efforts.

Again, many thanks and best wishes,

Andreas Schneck

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
