Preregistrationis the practice of registering the hypotheses, methods, or analyses of a scientific study before it is conducted.[1][2]Clinical trial registrationis similar, although it may not require the registration of a study's analysis protocol. Finally,registered reportsinclude the peer review and in principle acceptance of a study protocol prior to data collection.[3]
Preregistration can have a number of different goals,[4]including (a) facilitating and documenting research plans, (b) identifying and reducing questionable research practices and researcher biases,[5](c) distinguishing between confirmatory and exploratory analyses,[6](d) transparently evaluating the severity of hypothesis tests,[7]and, in the case of Registered Reports, (e) facilitating results-blind peer review, and (f) reducing publication bias.[8]
A number of research practices such asp-hacking,publication bias,data dredging,inappropriate forms ofpost hoc analysis,andHARKingmay increase the probability of incorrect claims. Although the idea of preregistration is old,[9]the practice of preregistering studies has gained prominence to mitigate to some of the issues that are thought to underlie thereplication crisis.[1]
Types
editStandard preregistration
editIn the standard preregistration format, researchers prepare a research protocol document prior to conducting their research. Ideally, this document indicates the research hypotheses, sampling procedure, sample size, research design, testing conditions, stimuli, measures, data coding and aggregation method, criteria for data exclusions, and statistical analyses, including potential variations on those analyses. This preregistration document is then posted on a publicly available website such as theOpen Science FrameworkorAsPredicted.The preregistered study is then conducted, and a report of the study and its results are submitted for publication together with access to the preregistration document. This preregistration approach allows peer reviewers and subsequent readers to cross-reference the preregistration document with the published research article in order to identify the presence of any undisclosed deviations of the preregistration. Deviations from the preregistration are possible and common in practice, but they should be transparently reported, and the consequences for the severity of the test should be evaluated.[10]
Registered reports
editThe registered report format requires authors to submit a description of the study methods and analyses prior to data collection.[11][12]Once the theoretical introduction, method, and analysis plan has been peer reviewed (Stage 1 peer review), publication of the findings is provisionally guaranteed (in principle acceptance). The proposed study is then performed, and the research report is submitted for Stage 2 peer review. Stage 2 peer review confirms that the actual research methods are consistent with the preregistered protocol, that quality thresholds are met (e.g., manipulation checks confirm the validity of the experimental manipulation), and that the conclusions follow from the data. Because studies are accepted for publication regardless of whether the results are statistically significant Registered Reports prevent publication bias. Meta-scientific research has shown that the percentage of non-significant results in Registered Reports is substantially higher than in standard publications.[13][14]
Specialised preregistration
editPreregistration can be used in relation to a variety of different research designs and methods, including:
- Quantitative research in psychology (Bosnjak et al., 2021)[15]
- Qualitative research (Haven & Van Grootel, 2019)[16]
- Preexisting data (Mertens & Krypotosm, 2019;Weston et al., 2019;van den Akker et al., 2021)[17][18][19]
- Single case designs (Johnson & Cook, 2019)[20]
- Electroencephalogram research (Paul et al., 2021)[21]
- Experience sampling (Kirtley et al., 2019)[22]
- Exploratory research (Dirnagl, 2020)[23]
- Animal Research (Bert et al., 2019)[24]
Clinical trial registration
editClinical trial registrationis the practice of documentingclinical trialsbefore they are performed in aclinical trials registryso as to combatpublication biasandselective reporting.[25]Registration of clinical trials is required in some countries and is increasingly being standardized.[26]Some top medical journals will only publish the results of trials that have been pre-registered.[27]
A clinical trials registry is a platform which catalogs registered clinical trials.ClinicalTrials.gov,run by theUnited States National Library of Medicine(NLM) was the first online registry for clinical trials, and remains the largest and most widely used. In addition to combating bias, clinical trial registries serve to increase transparency and access to clinical trials for the public. Clinical trials registries are often searchable (e.g. by disease/indication, drug, location, etc.). Trials are registered by the pharmaceutical, biotech or medical device company (Sponsor) or by the hospital or foundation which is sponsoring the study, or by another organization, such as acontract research organization(CRO) which is running the study.
There has been a push from governments and international organizations, especially since 2005, to make clinical trial information more widely available and to standardize registries and processes of registering. TheWorld Health Organizationis working toward "achieving consensus on both the minimal and the optimal operating standards for trial registration".[28]
Creation and development
editFor many years, scientists and others have worried about reporting biases such that negative or null results from initiated clinical trials may be less likely to be published than positive results, thus skewing the literature and our understanding of how well interventions work.[29]This worry has been international and written about for over 50 years.[30]One of the proposals to address this potential bias was a comprehensive register of initiated clinical trials that would inform the public which trials had been started.[31]Ethical issues were those that seemed to interest the public most, as trialists (including those with potential commercial gain) benefited from those who enrolled in trials, but were not required to “give back,” telling the public what they had learned.
Those who were particularly concerned by the double standard were systematic reviewers, those who summarize what is known from clinical trials. If the literature is skewed, then the results of a systematic review are also likely to be skewed, possibly favoring the test intervention when in fact the accumulated data do not show this, if all data were made public.
ClinicalTrials.govwas originally developed largely as a result of breast cancer consumer lobbying, which led to authorizing language in theFDA Modernization Act of 1997(Food and Drug Administration Modernization Act of 1997. Pub L No. 105-115, §113 Stat 2296), but the law provided neither funding nor a mechanism of enforcement. In addition, the law required that ClinicalTrials.gov only include trials of serious and life-threatening diseases.
Then, two events occurred in 2004 that increased public awareness of the problems of reporting bias. First, the then-New York State Attorney GeneralEliot SpitzersuedGlaxoSmithKline(GSK) because they had failed to reveal results from trials showing that certain antidepressants might be harmful.[32]
Shortly thereafter, theInternational Committee of Medical Journal Editors(ICMJE) announced that their journals would not publish reports of trials unless they had been registered. The ICMJE action was probably the most important motivator for trial registration, as investigators wanted to reserve the possibility that they could publish their results in prestigious journals, should they want to.
In 2007, theFood and Drug Administration Amendments Act of 2007(FDAAA) clarified the requirements for registration and also set penalties for non-compliance (Public Law 110-85. The Food and Drug Administration Amendments Act of 2007[1].
International participation
editTheInternational Committee of Medical Journal Editors(ICMJE) decided that from July 1, 2005 no trials will be considered for publication unless they are included on a clinical trials registry.[33][34]TheWorld Health Organizationhas begun the push for clinical trial registration with the initiation of theInternational Clinical Trials Registry Platform.There has also been action from the pharmaceutical industry, which released plans to make clinical trial data more transparent and publicly available. Released in October 2008, the revisedDeclaration of Helsinki,states that "Every clinical trial must be registered in a publicly accessible database before recruitment of the first subject."[35][36]
The World Health Organization maintains an international registry portal athttp://apps.who.int/trialsearch/.[37]WHO states that the international registry's mission is "to ensure that a complete view of research is accessible to all those involved in health care decision making. This will improve research transparency and will ultimately strengthen the validity and value of the scientific evidence base."[38]
Since 2007, theInternational Committee of Medical Journal EditorsICMJE accepts all primary registries in the WHO network in addition to clinicaltrials.gov. Clinical trial registration in other registries excluding ClinicalTrials.gov has increased irrespective of study designs since 2014.[39]
Reporting compliance
editVarious studies have measured the extent to which various trials are in compliance with the reporting standards of their registry.[40][41][42][43][44]
Overview of clinical trial registries
editWorldwide, there is growing number of registries. A 2013 study[45]identified the following top five registries (numbers updated as of August 2013):
1. | ClinicalTrials.gov | 150,551 |
2. | EU register | 21,060 |
3. | Japan registries network (JPRN) | 12,728 |
4. | ISRCTN | 11,794 |
5. | Australia and New Zealand (ANZCTR) | 8,216 |
Overview of preclinical study registries
editSimilar to clinical research, preregistration can help to improve transparency and quality of research data in preclinical research.[46][47]In contrast to clinical research where preregistration is mandatory for vast parts it is still new in preclinical research. A large part of preclinical and basic biomedical research relies on animal experiments. The non-publication of results gained from animal experiments not only distorts the state of research by reinforcing the publication bias, it further represents an ethical issue.[48][49]Preregistration is discussed as a measure that could counteract this problem. Following registries are suited for the preregistration of preclinical studies.

Journal support
editOver 200 journals offer a registered reports option (Centre for Open Science, 2019),[50]and the number of journals that are adopting registered reports is approximately doubling each year (Chambers et al., 2019).[51]
Psychological Sciencehas encouraged the preregistration of studies and the reporting of effect sizes and confidence intervals.[52]Theeditor-in-chiefalso noted that the editorial staff will be asking for replication of studies with surprising findings from examinations using small sample sizes before allowing the manuscripts to be published.
Nature Human Behaviourhas adopted the registered report format, as it “shift[s] the emphasis from the results of research to the questions that guide the research and the methods used to answer them”.[53]
European Journal of Personalitydefines this format: “In a registered report, authors create a study proposal that includes theoretical and empirical background, research questions/hypotheses, and pilot data (if available). Upon submission, this proposal will then be reviewed prior to data collection, and if accepted, the paper resulting from this peer-reviewed procedure will be published, regardless of the study outcomes.”[54]
Note that only a very small proportion of academic journals in psychology and neurosciences explicitly stated that they welcome submissions of replication studies in their aim and scope or instructions to authors.[55][56]This phenomenon does not encourage the reporting or even attempt on replication studies.
Overall, the number of participating journals is increasing, as indicated by theCenter for Open Science,which maintains a list of journals encouraging the submission of registered reports.[57]
Benefits
editSeveral articles have outlined the rationale for preregistration (e.g.,Lakens, 2019;Nosek et al., 2018;Wagenmakers et al., 2012).[6][58][1]The primary goal of preregistration is to improve the transparency of reported hypothesis tests, which allows readers to evaluate the extent to which decisions during the data analysis were pre-planned (maintaining statistical error control) or data-driven (increasing the Type 1 or Type 2 error rate).
Meta-scientific research has revealed additional benefits. Researchers indicate preregistering a study leads to a more carefully thought through research hypothesis, experimental design, and statistical analysis.[59][60]In addition, preregistration has been shown to encourage better learning of Open Science concepts and students felt that they understood their dissertation and it improved the clarity of the manuscript writing, promoted rigour and were more likely to avoid questionable research practices.[61][62]In addition, it becomes a tool that can supervisors can use to shape students to combat any questionable research practices.[63]
A 2024 study in theJournal of Political Economy: Microeconomicspreregistration in economics journals found that preregistration did not reduce p-hacking and publication bias, unless the preregistration was accompanied by a preanalysis plan.[64]
Criticisms
editProponents of preregistration have argued that it is "a method to increase the credibility of published results" (Nosek & Lakens, 2014), that it "makes your science better by increasing the credibility of your results" (Centre for Open Science), and that it "improves the interpretability and credibility of research findings" (Nosek et al., 2018,p. 2605).[1][65]This argument assumes that non-preregisteredexploratoryanalyses are less "credible" and/or "interpretable" than preregisteredconfirmatoryanalyses because they may involve "circular reasoning" in which post hoc hypotheses are based on the observed data (Nosek et al., 2018,p. 2600).[1]However, critics have argued that preregistration is not necessary to identify circular reasoning during exploratory analyses (Rubin, 2020). Circular reasoning can be identified by analysing the reasoning per se without needing to know whether that reasoning was preregistered. Critics have also noted that the idea that preregistration improves research credibility may deter researchers from undertaking non-preregistered exploratory analyses (Coffman & Niederle, 2015;see alsoCollins et al., 2021, Study 1).[66][67]In response, preregistration advocates have stressed that exploratory analyses are permitted in preregistered studies, and that the results of these analyses retain some value vis-a-vis hypothesis generation rather than hypothesis testing. Preregistration merely makes the distinction between confirmatory and exploratory research clearer (Nosek et al., 2018;Nosek & Lakens, 2014;Wagenmakers et al., 2012).[1][6][65]Hence, although preregistraton is supposed to reduceresearcher degrees of freedomduring the data analysis stage, it is also supposed to be “a plan, not a prison” (Dehaven, 2017).[68]However, critics counterargue that, if preregistration is only supposed to be a plan, and not a prison, then researchers should feel free to deviate from that plan and undertake exploratory analyses without fearing accusations of low research credibility due to circular reasoning and inappropriate research practices such asp-hacking and unreportedmultiple testingthat leads to inflatedfamilywise error rates(e.g.,Navarro, 2020).[69]Again, they have pointed out that preregistration is not necessary to address such concerns. For example, concerns aboutp-hacking and unreported multiple testing can be addressed if researchers engage in otheropen sciencepractices, such as (a) open data and research materials and (b) robustness or multiverse analyses(Rubin, 2020;Steegen et al., 2016;for several other approaches, seeSrivastava, 2018).[70][71][72]Finally, and more fundamentally, critics have argued that the distinction between confirmatory and exploratory analyses is unclear and/or irrelevant (Devezer et al., 2020;Rubin, 2020;Szollosi & Donkin, 2019),[73][70][74]and that concerns about inflated familywise error rates are unjustified when those error rates refer to abstract, atheoretical studywise hypotheses that are not being tested (Rubin,2020,2021;Szollosi et al., 2020).[70][75][76]
There are also concerns about the practical implementation of preregistration. Many preregistered protocols leave plenty of room forp-hacking (Bakker et al., 2020;Heirene et al., 2021;Ikeda et al., 2019;Singh et al., 2021;Van den Akker et al., 2023),[77][78][79][80][81]and researchers rarely follow the exact research methods and analyses that they preregister (Abrams et al., 2020;Claesen et al., 2019;Heirene et al., 2021;see alsoBoghdadly et al., 2018;Singh et al., 2021;Sun et al., 2019).[82][83][84][85][79][80]For example, pre-registered studies are only of higher quality than non-pre-registered studies if the former has a power analysis and higher sample size than the latter but other than that they do not seem to prevent p-hacking and HARKing, as both the proportion of positive results and effect sizes are similar between preregistered and non-preregistered studies (Van den Akker et al., 2023).[81]In addition, a survey of 27 preregistered studies found that researchers deviated from their preregistered plans in all cases (Claesen et al., 2019).[83]The most frequent deviations were with regards to the planned sample size, exclusion criteria, and statistical model. Hence, what were intended as preregistered confirmatory tests ended up as unplanned exploratory tests. Again, preregistration advocates argue that deviations from preregistered plans are acceptable as long as they are reported transparently and justified. They also point out that even vague preregistrations help to reduceresearcher degrees of freedomand make any residual flexibility transparent (Simmons et al., 2021, p. 180).[86]However, critics have argued that it is not useful to identify or justify deviations from preregistered plans when those plans do not reflecthigh quality theory and research practice.AsRubin (2020)explained, “we should be more interested in the rationale for thecurrentmethod and analyses than in the rationale forhistoricalchanges that have led up to the current method and analyses” (pp. 378–379).[70]In addition, pre-registering a study requires careful deliberation about the study's hypotheses, research design and statistical analyses. This depends on the use of pre-registration templates that provides detailed guidance on what to include and why (Bowman et al., 2016;Haven & Van Grootel, 2019;Van den Akker et al., 2021).[87][88][89]Many pre-registration template stress the importance of a power analysis but not only stress the importance of why the methodology was used. Additionally to the concerns raised about its practical implementation in quantitative research, critics have also argued that preregistration is less applicable, or even unsuitable, for qualitative research.[90]Pre-registration imposes rigidity, limiting researchers' ability to adapt to emerging data and evolving contexts, which are essential to capturing the richness of participants' lived experiences (Souza-Neto & Moyle, 2025).[91]Additionally, it conflicts with the inductive and flexible nature of theory-building in qualitative research, constraining the exploratory approach that is central to this methodology (Souza-Neto & Moyle, 2025).[91]
Finally, some commentators have argued that, under some circumstances, preregistration may actually harm science by providing a false sense of credibility to research studies and analyses (Devezer et al., 2020;McPhetres, 2020;Pham & Oh, 2020;Szollosi et al., 2020).[73][92][75][93]Consistent with this view, there is some evidence that researchers view registered reports as being more credible than standard reports on a range of dimensions (Soderberg et al., 2020;see alsoField et al., 2020for inconclusive evidence),[94][95]although it is unclear whether this represents a "false" sense of credibility due to pre-existing positive community attitudes about preregistration or a genuine causal effect of registered reports on quality of research.
