재현성과 부정적 결과

Science corrects itself only when failures are recorded: replications that did not reproduce, experiments that found nothing, errors found after publication. Many of these records never appear, so the published literature overstates effects and certainty. This page sets out how irreproducibility arises, how replication and correction work, which records exist, and what editors, integrity offices and funders rely on when they correct or retract.

Reproducibility and negative results on the record.

02질문

Reproducibility and negative results: how the risk develops.

Failure records and corrections. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

메커니즘

Publication bias filters the record

Significant, novel results are more likely to be written up, accepted and cited than null ones. The literature then shows a biased sample of what was studied, and meta-analyses inherit the bias.

메커니즘

Errors propagate through citation

A flawed or retracted paper keeps being cited, often without mention of its status. Reviews, guidelines and later studies that build on it carry the error forward, sometimes long after the notice.

메커니즘

Reproduction fails for ordinary reasons

Missing code, undocumented software versions, unshared reagents, unclear methods and lost raw data stop others from repeating an analysis or experiment, even when the original work was honest.

메커니즘

Correction is slow and uneven

Investigations take time, journals differ in how they flag problems, and retraction notices can be vague. Readers may not learn that a paper was corrected, and databases may not carry the notice forward.

09핵심 질문

What experts ask about reproducibility.

  • Can an independent team re-run the analysis from the published data and code?
  • Has the finding been replicated with new data, in a new setting or by a different team?
  • Which null or negative results exist, and where are they recorded?
  • When an error is found, how is it corrected and how are users of the result told?
  • Which parts of a workflow, such as software versions or random seeds, could change the answer?
10메커니즘과 동인

Why results fail to reproduce.

Many published findings in several disciplines have proved difficult to replicate. The causes are well understood: small samples, flexible analysis, selective reporting, undocumented data processing and incentives that favour novel positive findings. In computational work, results can also depend on software versions, hardware, random seeds and data that change after publication.

Negative results are under-reported because they are harder to publish and seem less interesting. This distorts the evidence base: if only successful trials of an intervention are visible, the intervention looks more effective than it is. Systematic reviews and models built on that evidence inherit the bias.

Corrections matter for the same reason. An error in a widely used dataset or model can propagate into many downstream analyses before it is found.

11방법과 데이터

Practices that support reproducibility.

  1. 01

    Open data and code

    Sharing the materials needed to re-run an analysis, within privacy and licensing limits. Some data cannot be shared and must be described instead.

  2. 02

    Computational environments

    Recording software versions and environments, a practice developed with 재현 가능한 모델링. Long-term preservation remains hard.

  3. 03

    Registered reports

    Peer review of the protocol before results exist, so publication does not depend on the outcome.

  4. 04

    Correction records

    Dated, visible corrections linked to the original result, rather than silent replacement.

A failed replication does not by itself show the original was wrong; differences in setting, sample or method must be examined before conclusions are drawn.

14질문

질문과 답변.

What is the difference between reproducibility and replicability?
In the usage of the US National Academies, reproducibility means obtaining the same results from the same data and code, and replicability means obtaining consistent results from new data. Usage varies by field, so definitions should be stated.
Why publish negative results?
They show what did not work, prevent wasted repetition and correct the bias that makes effects look larger than they are. A well-designed study with a null result is a finding.
Does retraction always mean misconduct?
No. Papers are also retracted for honest error, irreproducible results or publisher problems. COPE guidance asks that each notice states the reason.
Can a retracted paper still be cited?
It can be cited as retracted, for example in studies of the literature. Citing it as valid evidence is an error that reviewers and editors should catch.
Will Labs publish a study that found nothing?
Yes. A well-conducted study with a null result is designed to be recorded with the same detail as a positive one.
How do I report an error in a Labs result?
Use the correction routes on the Labs trust page으로 보내 주십시오. 접수 확인에는 참조 번호와 다음 단계가 안내됩니다.
Are corrected results removed?
No. The original stays visible with a dated correction, so anyone who used it can see what changed.
