Transparency & Replication Data (bjps-transparency-and-data)

BJPS is a signatory of the Data Access and Research Transparency (DA-RT) statement: authors "are not allowed to withhold information used to perform an analysis featured in a BJPolS piece." At acceptance, replication data and code are deposited in the BJPolS Dataverse on Harvard Dataverse, which issues a citable DOI for the data. Build the package as you go so acceptance does not stall.

When to trigger

• Building the replication / transparency package
• A manuscript reached acceptance and you must deposit materials
• Data cannot be fully shared (privacy, ethics, legal/provider restrictions) and you need the

restricted-access exemption path

• A Comment that re-analyzes a published result (materials expectations are central)

What BJPS requires (verify current wording on the policy page)

1. Deposit to the BJPolS Dataverse. Replication data and code are uploaded to the **BJPolS

Dataverse on Harvard Dataverse, the journal's dedicated collection with permanent identifiers; you receive citation information including a DOI** for the data. Not a personal website or generic cloud link.

1. No withholding. You may not withhold information used to produce an analysis in the paper.

Treat the deposit as enabling independent replication, not as a formality.

1. Quantitative materials. Data, code, and documentation sufficient to regenerate every reported

result. Master script + README + pinned versions + seeds.

1. Qualitative materials. Share the materials and evidence used to support the claims (e.g.,

evidence tables, annotated sources, interview protocols), with access controls where needed (the Qualitative Data Repository, QDR, supports controlled access).

When data cannot be shared (restricted-access exemption)

• Explain why the relevant data are not available — BJPS allows exemptions for **restricted-access

source data** (ethical/privacy concerns or provider/legal restrictions).

• Provide README instructions on exactly how others can obtain the data (access process,

application, provider contact).

• Where possible, provide synthetic data resembling the unavailable data so the code can be run.
• Questions about the replication policy can be directed to the BJPolS editorial staff (待核实 current

contact on the live policy page).

Build-as-you-go checklist

• [ ] One master script regenerates every table and figure from raw/constructed data
• [ ] README documents data provenance, construction steps, and how to reproduce each exhibit
• [ ] Seeds set and reported for every stochastic step
• [ ] Software/package versions pinned (renv.lock / requirements.txt / recorded installs)
• [ ] Exhibit numbers in the manuscript match the package output exactly
• [ ] Restricted data: exemption note + access instructions + synthetic data where feasible
• [ ] Preregistration / pre-analysis plan linked (anonymized) where applicable

Anti-patterns

• Treating the deposit as a post-acceptance afterthought
• Depositing code that does not actually reproduce the printed tables/figures
• A personal URL instead of the BJPolS Dataverse
• Claiming data are restricted without giving an access path or synthetic substitute
• Undocumented, un-seeded, unpinned code that "works on my machine"
