Transparency and Openness Promotion (TOP) standards for Evolution and Human Behavior

As of January 1st, 2017, Evolution and Human Behavior is adopting policies regarding transparency and openness, drawing on the Center for Open Science's Transparency and Openness Promotion Guidelines. After considering the full array of options, the editorial board has decided to adopt the policies indicated on this page.

A: Citation and data transparency standard

It is the policy of EHB to publish papers only if the data are clearly and precisely documented and are maximally available to any researcher for purposes of reproducing the results or replicating the procedure. Authors using original data must make the data available at a trusted digital repository or as online Supplementary Material. Data files should allow for the reproduction of all calculations reported in your paper. Datasets must be in an easily accessible format amenable to analysis (e.g., CSV file, excel file, etc.) Citation of data files and materials should be included in the manuscript. Data collected on humans must be fully de-identified. Data should be deposited once the article has been editorially accepted for publication. (We recommend, but do not require, making use of the Open Science Framework for sharing your data.) Your final submission must include a link to your data in a separate section before the Acknowledgments. This link need not be present at submission (because it might undermine blinding) but must be added before the paper is accepted.

In rare cases, despite authors' best efforts, some or all data cannot be shared for legal or ethical reasons. In such cases, authors must inform the editors at the time of submission. This will be taken into account during the review process. Authors are encouraged to anticipate data sharing at the beginning of their projects to provide for these circumstances. It is understood that in some cases access will be provided under restrictions to protect confidential or proprietary information. Editors may grant exceptions to data access requirements provided authors: (a) explain the restrictions on the dataset and how they preclude public access. (b) provide a public description of the steps others should follow to request access to the data. (c) provide software and other documentation that will precisely reproduce all published results. (d) provide access to all data for which the constraints do not apply.

B: Analytic methods (code) and research materials transparency

EHB encourages authors to share all analytic methods (e.g., code, scripts, and other documentation) and research materials used to conduct the published research in sufficient detail to conduct an independent replication of the research.

C: Design and analysis transparency

EHB encourages authors to include information regarding research design and data analyses in sufficient detail such that a third party can conduct an independent replication of the research.

D: Preregistration of studies and analysis plans

It is a policy of EHB to publish papers where authors are given the opportunity to indicate that the conducted research was preregistered with an analysis plan in an independent, institutional registry. Preregistration of studies involves registering the study design, variables, and, if appropriate, treatment conditions. Including an analysis plan involves specification of sequence of analyses or the statistical model that will be reported.

Authors must, in acknowledgements or the first footnote, indicate if they preregistered the research with or without an analysis plan in an independent institutional registry.

If an author did preregister the research with an analysis plan, the author must: (a) confirm in the text that the study was registered prior to conducting the research with links to the time-stamped preregistrations at the institutional registry. (b) report all pre-registered analyses in the text, or, if there were changes in the analysis plan following preregistration, those changes must be disclosed with explanation for the changes. (c) Clearly distinguish in text analyses that were preregistered from those that were not, such as having separate sections in the results for confirmatory and exploratory analyses.

E: Replication

EHB encourages submission of replication studies, particularly of research published in this journal.

Summary of Adopted TOP Guidelines



Standards TOP level


Citation Standards 2: Article provides appropriate citation for data used consistent with journal's author guidelines (see A).


Data Transparency 2: Data must be posted to a trusted repository. Exceptions must be identified at article submission (see A).


Analytic Methods (Code) Transparency /
Research Material Transparency
1: Journal guidelines encourage the sharing of analytic methods and research materials without requiring article to state whether such materials are available and how to access them (see B).


Design and Analysis Transparency 1: Journal encourages design and analysis transparency, or says nothing (see C).


Preregistration of Studies /
Preregistration of Analysis Plans
1: Journal encourages preregistration of studies and analysis plans and provides link in article to registered plan if it exists (see D).


Replication 1: Journal encourages submission of replication studies (see E).
