SCENA ZNANOSTI

How science actually happens: peer review, preprints, corrections, and what never gets published.

An AKTUAL MEDIA edition · GNK ASG network

Reproduction

Reproduction: the most important experiment is someone else’s

A result nobody can repeat is not a result but an event. Reproduction is therefore the least attractive and most important part of science.

SCENA ZNANOSTI — Reproduction
Network notice. This is an independent edition inside the GNK ASG network. The main site is gnk-asg.hr; the list of all editions is at gnk-asg.hr/en/network. The publisher is AKTUAL MEDIA d.o.o., and every text in the network is listed at AKTUAL MEDIA — network of editions. Editor and director: Nermin Sefić.

The desk does not run research or peer-review papers. It carries published documents and marks what is peer-reviewed and what is not.

01Why replication attempts fail

The reasons are usually boring: too small a sample, a method description missing detail, different instruments, or an analysis chosen after seeing the result. Fraud is rarer than an under-documented procedure.

Good practice therefore asks for preregistration and data sharing. That is not bureaucracy; it is what lets someone else repeat what you did.

02What a reader can check alone

Does the paper have a DOI, is the sample stated, is there a limitations section, and is a conflict of interest declared. Those four questions separate a serious source from an impression.

  • DOI and a persistent address
  • Sample and period
  • A limitations section
  • Shared data and code where possible

Questions that keep coming back

How much of science has been reproduced?

There is no single figure that holds across fields; estimates differ by area and method. That is why we cite individual cases with sources rather than a general percentage.

Sources

Every source below is public and checkable. Where a page cites a figure, the figure comes from one of these documents — and the document has a date.

  1. arXivThe largest preprint server; papers before review, clearly marked as not peer reviewed.
  2. NatureJournal and an explanation of its own editorial process.
  3. ScienceJournal and its corrections and retraction policy.
  4. Retraction WatchA database of retracted papers and the reasons behind retractions.
  5. PubPeerPublic post-publication discussion of published papers.
  6. DOI FoundationA persistent identifier; a link that does not depend on the journal’s URL.
  7. Hrvatska zaklada za znanostNational research funding and public project information.
