Preregistration in animal research is the practice of registering study designs and analysis plans before data collection. According to Priboi et al. (2026) in PLoS Biology, adoption is low and resistance is high, yet targeted education and structural support could change that. This post explains what the PLoS Biology survey measured, quotes key findings, and shows how AI-enabled qualitative research methods can turn the survey's open-ended responses into operational steps for research teams, funders, and policy makers.
Key Takeaways
According to Priboi et al. (2026) in PLoS Biology, preregistration remains uncommon among Swiss animal study directors, and practical barriers dominate attitudes. The PLoS Biology survey collected 418 complete responses between 29 May 2024 and 26 June 2024 and identifies clear levers for targeted interventions.
- Priboi et al. (2026) report that of 1, 385 study directors contacted between 29 May 2024 and 26 June 2024, 418 completed the survey, a 30.2% response rate.
- Priboi et al. (2026) found only 10.0% of respondents had preregistered at least one study, and 39.2% had never heard of preregistration prior to the survey.
- Priboi et al. (2026) measured barriers quantitatively: bureaucratic burden (77.6%), time costs (71.4%), and low flexibility (65.7%) were the most frequently reported obstacles.
- Priboi et al. (2026) report that those with preregistration experience held more favorable attitudes, while more senior researchers reported more negative perceptions.
What happened and how it was measured
The PLoS Biology survey assessed Swiss accredited animal study directors’ experiences and attitudes toward preregistration using a preregistered cross-sectional online questionnaire. Priboi et al. (2026) state data collection occurred between 29 May 2024 and 26 June 2024, and recruitment was managed by the Federal Food Safety and Veterinary Office.
Priboi et al. (2026) combined closed-ended Likert scales (attitudes, subjective norms, perceived behavioral control, intentions, motivations, obstacles) with inductive thematic analysis of open-ended questions to capture both quantitative patterns and qualitative reasons for resistance.
"Only 10% had preregistered studies before participating in the survey, " Priboi et al. (2026) report, and the authors note that many open-ended responses reflected misconceptions about flexibility and scooping.
Priboi et al. (2026) applied principal component analysis and reliability checks to validate scales, and they used thematic coding with example quotations to synthesize barriers, facilitators, and suggestions.

Implications for research teams and stakeholders: preregistration in animal research
The primary implication is that awareness, usability, and incentives must be addressed before expecting widespread adoption of preregistration in animal research. Priboi et al. (2026) show that a large share of the community is unaware (39.2%) or views preregistration as added bureaucracy.
Priboi et al. (2026) recommend targeted education because misconceptions drive resistance: many respondents conflated preregistration with the legal authorization procedure and believed preregistration forbids legitimate deviations from plans.
For institutional leaders and funders, Priboi et al. (2026) highlight that policy levers matter: nearly half of respondents indicated institutional policies would influence their decision to preregister.
For ethics committees and Animal Welfare Officers, Priboi et al. (2026) suggest aligning authorization workflows with flexible preregistration templates can reduce duplication and perceived burden.
How Evidano helps: map problems to AI-enabled qualitative solutions
Problem: Low awareness and misunderstood concepts → Solution: rapid thematic and content analysis
Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents.
Priboi et al. (2026) found 39.2% of respondents had never heard of preregistration, a finding that can be verified and tracked across institutions by analyzing open-ended responses with automated thematic coding.
Evidano feature mapping: use thematic, content frequency, and hierarchical code analyses to quantify misconceptions, tag example quotations (e.g., "preregistration is a plan, not a prison"), and produce shareable summaries for training sessions. See Evidano features for relevant tools.
Problem: Practical friction (bureaucracy, time) → Solution: UX-informed templates and segment analysis
Priboi et al. (2026) report bureaucratic burden (77.6%) and time costs (71.4%) as dominant barriers; reducing friction requires both design changes and evidence that those changes work.
Evidano feature mapping: analyze open-text suggestions to create prioritized UX improvements, then run cross-segment analyses (seniority, field, preregistration experience) to identify which template changes reduce perceived effort most effectively. For automated transcription or note ingestion, teams can combine survey text with interview transcripts using Evidano speech-to-text.
Problem: Discipline differences and seniority effects → Solution: targeted messaging and monitoring
Priboi et al. (2026) show more experienced researchers reported more negative perceptions, while researchers in General Biology were relatively more positive.
Evidano feature mapping: run segment-specific thematic comparisons to craft discipline-tailored case studies and track attitude change over time after interventions such as workshops or policy changes. Use Evidano AI chat over coded documents to generate briefings for senior stakeholders.
Problem: Need for evidence on impact → Solution: mixed-method synthesis and extractable evidence
Priboi et al. (2026) call for proof that preregistration improves research quality; policymakers need succinct, evidence-backed narratives.
Evidano feature mapping: synthesize quantitative survey scales with coded qualitative themes to produce extractable answers, frequency tables, and quotable summaries that include direct quotations and percentages ready for reports and grant applications. For reproducible workflows, link analysis outputs to study metadata and export figures for institutional briefings.
FAQ: preregistration in animal research
What are the main barriers to preregistration in animal research?
The main barriers are practical: bureaucratic burden, time costs, and concerns about low flexibility. Priboi et al. (2026) report 77.6% cited bureaucratic burden, 71.4% cited time costs, and 65.7% cited low flexibility in their closed-ended items.
The survey's thematic analysis also identified knowledge gaps and fears of being scooped as recurring themes, which can be addressed through education and templating.
Can preregistration be used for exploratory or discovery-driven animal studies?
Yes, preregistration can be used for exploratory research when documented flexibly; it is not meant to lock researchers into a single plan. Priboi et al. (2026) note the misconception that preregistration "stifles creativity" is common, and they cite literature framing preregistration as a "plan, not a prison."
Priboi et al. (2026) recommend templates and guidance that explicitly allow documented deviations to preserve exploratory workflows.
How long does preregistration add to project setup?
Reported median time for those with preregistration experience was about 11 hours per preregistration in the PLoS Biology survey. Priboi et al. (2026) report experienced participants had a median of 3 preregistered studies and estimated a median time of 11 hours per preregistered study.
Teams can measure and reduce this overhead by improving templates and integrating preregistration with existing authorization forms, as participants recommended.
How should institutions measure whether interventions increase preregistration uptake?
Measure awareness, attitudes, intentions, and actual preregistration counts before and after interventions. Priboi et al. (2026) used validated psychosocial scales and open-ended items to link attitudes and experience to behavior.
Use mixed-method monitoring: repeated short surveys plus AI-enabled coding of open responses to track changing barriers and new practical issues in real time.
How can AI help with analyzing open-ended survey responses about preregistration?
AI-enabled qualitative platforms can accelerate coding, surface prevalent themes, and quantify theme frequencies across segments. Priboi et al. (2026) used inductive thematic analysis to summarize responses from up to 334 participants on open-ended items, a workload that scales poorly without AI support.
Automated thematic extraction combined with human validation yields reproducible codebooks, quotable examples, and cross-segment metrics that stakeholders can use to prioritize interventions.
Conclusion & Next Steps
Priboi et al. (2026) in PLoS Biology provide clear, quantified reasons why preregistration uptake in animal research is low: awareness gaps, perceived bureaucracy, and discipline- and seniority-driven resistance.
AI-enabled qualitative research converts those open-ended concerns into prioritized, testable interventions: targeted training, streamlined templates, confidentiality measures, and aligned incentives.
If your team needs a reproducible way to code open responses, quantify barriers by segment, and produce quotable evidence for funders or institutional leadership, an AI qualitative platform can accelerate the work. Try a practical, hands-on approach and measure change.
