A transparent universal credit system to incentivize peer review

The paper addresses a growing crisis in academic peer review: editors increasingly struggle to find reviewers, with invitations per completed review rising and invitations growing twice as fast as article publications between 2013 and 2017. Framed as a public-goods dilemma where free-riding is advantageous, the current system risks collapse as contributors withdraw effort. The authors propose a universal, transparent credit-based mechanism—Peer Review by Reciprocity—to deter free-riding, reward participation, and place peer review on more sustainable foundations.

The authors synthesize evidence that reviewer recruitment has become harder, citing increases in review invitations, editor reports that finding reviewers is the most challenging task, and rising submission rates. They connect peer review to theories of cooperation and public-goods games, highlighting risks of free-riding and the ‘tragedy of the commons.’ They review prior reform attempts (e.g., Axios Review, Peerage of Science, monetary payment to reviewers, continuing medical education credits) and argue these had limited impact due to publisher-specific systems and the scale of change required, making cross-publisher tracking and reform hard to implement.

As an opinion proposing a systems intervention, the paper details the design of ‘Peer Review by Reciprocity’ (Reciprocity):

• Credit payment rules: Authors must pay two review credits to submit a manuscript. If desk-rejected, one credit is refunded (one retained for editor assessment). If sent for review, both credits are consumed regardless of outcome. Resubmissions to the same journal (including as a new manuscript) require no additional credits; submissions to a different journal require two new credits. Transfers to affiliated journals without additional review do not require new credits. Credits can be contributed by any coauthor and shared among authors (e.g., supervisors supporting students).
• Earning credits: Credits are earned by reviewing or acting as a handling editor, for each review/decision meeting minimum quality standards, including reviews of resubmissions. Credits cannot be bought or sold. To promote mentoring, if an early-career researcher conducts their first review with a mentor, both receive a credit. Reviews at any ISI-listed journal qualify, allowing individuals to earn credits without supporting for-profit publishers.
• Infrastructure: The system would piggyback on ORCID, which already tracks both reviewing and authorship. ORCID would maintain secure Reciprocity credit balances; nearly 11 million researchers are enrolled, facilitating universal adoption.
• Waivers: To avoid excluding those not yet invited to review (e.g., early-career researchers, researchers in developing countries) or urgent cases (e.g., time-critical public health work), journals can grant waivers akin to APC waivers. Waived credits would be recorded in ORCID for tracking. Publishers/journals could maintain registries of waived authors and their expertise to facilitate future reviewer invitations.
• Rollout and economy design: The system would start from a defined date; prior reviews/submissions would not count. Each author receives three free credits upon account establishment, usable within the first year. The economy is intentionally non-zero-sum: while a typical reviewed submission entails at least three assessments (handling editor plus two reviewers), authors pay only two credits to prevent credit scarcity (e.g., from retirees or net-positive contributors). Costs and rewards can be tuned after observing behavior.
• Administrative and security needs: Implementation requires an accounting system integrated with ORCID’s review tracking, resources and staff, and robust security to prevent manipulation or counterfeiting, drawing on models from banking, reward points, or CME systems. Some researchers may object to ORCID participation and visibility of review activity as a condition of being an active, published researcher.

This opinion piece advances a policy design rather than empirical findings. The authors argue that Reciprocity would: (1) deter free-riding and reward participation by linking the ability to submit to the performance of reviewing/editing work; (2) increase reviewer supply, reduce editorial administrative burden, and accelerate publication timelines; (3) impose nonfinancial costs on speculative ‘Hail Mary’ submissions, leading to more judicious journal targeting and fewer unnecessary reviews; (4) broaden the reviewer pool and distribute workload more equitably, freeing time for those who currently review disproportionately; (5) provide recognition for the substantial, often invisible, community contribution of peer reviewing; and (6) enable institutions to value reviewing (e.g., via university rankings) and extend the credit system to grant and thesis reviews. The non-zero-sum design (two credits charged Vs three or more assessments performed) is intended to avoid credit scarcity and ensure system fluidity.

By reframing peer review as a public-goods game susceptible to free-riding, the proposed credit system aligns individual incentives with community needs. Requiring credits to submit ensures that authors contribute proportionally to the review ecosystem, stabilizing cooperation. Universal tracking via ORCID enhances transparency and portability across publishers. Waivers and mentoring incentives aim to ensure equity and on-ramping for new reviewers while seeding future reviewer pools. The expected benefits—faster processing, reduced editor burden, fairer workload distribution, and curbing low-probability submissions—address root causes of reviewer fatigue. The approach also offers a pathway to institutional recognition of reviewing and potential integration into broader academic evaluation metrics. Challenges include building secure credit accounting, community buy-in, and managing objections from those who engage minimally in review.

The paper proposes ‘Peer Review by Reciprocity,’ a transparent, universal credit system to incentivize and equitably distribute peer-review labor. By tying manuscript submission to earned review credits, leveraging ORCID for tracking, and incorporating waivers and mentoring incentives, the system seeks to deter free-riding and sustain peer review. The authors invite community discussion on implementation details, anticipate iterative adjustments to credit costs/rewards based on data, and suggest future extensions to university ranking systems and to other evaluative processes (grants, theses). They argue that broad adoption would recognize and protect the collective service that underpins research quality.

The authors acknowledge several risks and implementation challenges: (1) system development and maintenance costs, need for secure accounting integrated with ORCID, and risk of manipulation or counterfeiting; (2) potential resistance from researchers opposed to mandatory ORCID participation or increased transparency of reviewing; (3) gaming avenues and mitigations—purchasing authorship in exchange for credits (countered by strict authorship criteria), low-quality or AI-generated reviews (requiring editorial quality checks and possibly multi-person credit refusal processes), paid third-party reviewing (hard to detect if quality is met), and journals freeloading by offering credit-free publications (monitored via credit flow with potential exclusion from the system); (4) equity concerns if waivers are inconsistently applied; and (5) the need to calibrate the non-zero-sum credit economy to prevent scarcity or inflation as behavior data emerge.
