Motivation and concerns regarding the use of preprints among Brazilian health researchers: a survey

Science has long relied on a slow, careful gatekeeping process. Before a new discovery is shared with the world, it is usually sent to a panel of experts who check the work for errors and fairness. This peer review system is meant to ensure quality, but it can take months or even years for a paper to pass through the gates. In recent years, a different approach has emerged to speed things up. Researchers can now post their work online immediately, before any expert has looked at it. These early drafts are called preprints. They act like a public announcement of a finding, allowing others to see the work right away, offer comments, or build upon it. While this method promises to make science faster and more open, it remains a mystery to many scientists whether it is actually useful or if it carries too much risk.

A team of researchers in Brazil decided to investigate how health scientists in their country feel about this new way of sharing. They focused on a specific group: 1,596 highly experienced researchers who had received prestigious government grants for their work in fields like dentistry, medicine, and nursing. These are the people who are often leading the most important studies. The team sent a detailed survey to these scientists to ask why they might choose to post their work early, or why they might choose to wait. The goal was to understand the real reasons behind the decision to use or ignore preprints, moving beyond simple assumptions to hear directly from the scientists themselves.

The results revealed a clear divide. Out of the researchers who responded, nearly two-thirds had never posted a preprint of their own work. For those who had, the main reason was simple: they wanted to share their findings quickly and get feedback from colleagues before the long wait for formal publication. They saw value in having their work visible immediately. However, for the majority who had not used the system, the reason was not that they did not know it existed. Most of them knew about preprints but simply chose not to use them. Their hesitation often came down to a belief that their work needed the safety and validation of the traditional peer review process before it could be shown to the public. They felt that posting an unreviewed draft might confuse readers or even harm their chances of publishing in a respected journal later.

The study also looked at whether outside forces were pushing scientists toward preprints. The researchers found that neither their universities nor their funding agencies were forcing them to post early drafts. The decision remained almost entirely in the hands of the individual scientist. Furthermore, the data suggested that posting a preprint did not automatically lead to more citations or wider attention in the way some open science advocates had hoped. While a small number of scientists believed it helped their work get noticed, most remained neutral or skeptical about whether it actually boosted the impact of their research.

Ultimately, the survey painted a picture of a scientific community that is cautious but informed. The barrier to using preprints in Brazilian health research is not a lack of knowledge or a lack of tools. Instead, it is a deliberate choice made by scientists who weigh the speed of sharing against the security of traditional review. They are aware of the option to post early, but for many, the value of having their work vetted by experts first still outweighs the benefits of immediate release. This suggests that for preprints to become a standard part of health research, the scientific community may need to address the specific concerns about quality and safety that currently keep these experienced researchers waiting.
