    The idea

    Before a study appears in a journal, or a grant is awarded, other experts in the same field read it anonymously and recommend acceptance, revision or rejection. They judge originality and importance, whether the method and the statistics really support the conclusions, and whether anything has been overstated. Three functions are worth naming: allocating research funding, validating the quality of what gets published, and improving the work through suggested amendments. The evaluation is the more valuable half. Anonymity can shelter a reviewer settling a rivalry; journals prefer positive, novel results, so replications and null findings go unpublished, which is the file drawer problem; and established reviewers may suppress work that threatens the theory their own careers rest on, slowing any paradigm shift.

    What earns the marks

    • Describes the process as independent assessment by experts in the same field before publication or funding.
    • States the criteria assessed: originality, significance, methodological quality and whether conclusions follow from the data.
    • Names the functions of allocating funding, validating research quality and improving the manuscript.
    • Evaluates using anonymity and the possibility of bias or rivalry.
    • Evaluates using publication bias towards positive findings and the burying of replications and null results.

    Common mistakes and how to put them right

    • Describing it as checking that the results are correct, when reviewers cannot see the raw data or rerun the study.

    • Saying reviewers are chosen from other disciplines to stay neutral.

      Put it right: They are experts in the same field.

    • Offering only the vague criticism that reviewers can be biased, without naming rivalry, publication bias or the file drawer problem.

    • Ignoring the funding role and treating peer review as only a publication gate.

    Exam tips

    • An evaluation question wants both the purpose and the flaws, so plan two of each before writing.
    • Link it to features of science, particularly objectivity and replicability, to lift an answer into the top band.
    • Use the file drawer problem by name; the specific term is what distinguishes a top-band point from 'some studies are not published'.

    Before a study appears in a journal, or a grant is awarded, other experts in the same field read it anonymously and recommend acceptance, revision or rejection. They judge originality and importance, whether the method and the statistics really support the conclusions, and whether anything has been overstated. Three functions are worth naming: allocating research funding, validating the quality of what gets published, and improving the work through suggested amendments.

Anonymity can shelter a reviewer settling a rivalry; journals prefer positive, novel results, so replications and null findings go unpublished, which is the file drawer problem; and established reviewers may suppress work that threatens the theory their own careers rest on, slowing any paradigm shift. A strong answer earns marks for these points. Describes the process as independent assessment by experts in the same field before publication or funding. States the criteria assessed: originality, significance, methodological quality and whether conclusions follow from the data. Names the functions of allocating funding, validating research quality and improving the manuscript. Evaluates using anonymity and the possibility of bias or rivalry.

    A top-down flowchart. A box labelled 'Study or grant submitted' leads to a box labelled 'Experts in the same field read it anonymously'. From that box three arrows lead to three parallel boxes: 'Judge originality and importance', 'Judge whether method and statistics support conclusions', and 'Judge whether anything has been overstated'. All three lead to a box labelled 'Recommend acceptance, revision or rejection'. From that box three arrows lead to three final boxes: 'Functions: allocate research funding', 'Functions: validate quality of published work', and 'Functions: improve work through suggested amendments'.
    It shows the peer review process from submission through anonymous expert assessment and recommendation to the three named functions.

    Allocation of funding
    One function of peer review, where experts judge a study before a grant is awarded.
    Validation of research quality
    One function of peer review, judging whether the method and statistics really support the conclusions before a study appears in a journal.
    Publication bias and the file drawer problem
    Journals prefer positive, novel results, so replications and null findings go unpublished.
