Medical research helps us diagnose diseases earlier, treat them more effectively, and prevent them entirely. But none of this would be possible without people willing to take part in studies. And that’s where a major challenge appears: recruiting participants is not easy.
This raises a simple but important question: what factors make some people willing to take part in medical research while others hesitate?
What we wanted to find out
Previous research has identified a range of factors associated with participation in medical research. However, researchers have given surprisingly little attention to the role of scientific literacy—that is, how people think about, understand, and engage with science. At the same time, we know that people’s beliefs about medical researchers—especially whether they trust them or believe in conspiracy theories about them—are likely to play a role.
To explore how these factors relate to willingness to participate in medical research, we surveyed adults from the general population.
Trust and conspiracy beliefs matter most
One of the key factors related to willingness to participate in medical research was trust in medical researchers. People who saw them as honest, competent, and concerned with participants’ safety were much more willing to take part.
In addition, we also examined conspiracy beliefs about medical researchers—for example, the belief that researchers manipulate data, hide information, or act in the interests of powerful groups. People who were more likely to endorse these beliefs tended to trust medical researchers less and were also less willing to participate.
In other words, people’s views of medical researchers are closely linked to their willingness to take part in research.
How scientific literacy fits into the picture
We also looked at how scientific literacy relates to these beliefs. Of the four aspects of scientific literacy we examined, we focused on two here: positive beliefs about science, reflecting whether people see science as valuable and credible, and interest in science, which captures whether people are engaged with science. We found that people who scored higher on these dimensions also tended to view medical researchers more positively. Specifically, they tended to trust them more and were less likely to endorse conspiracy beliefs about them. In turn, they were more willing to participate in medical research.
Overall, people with more positive views of science and greater engagement with it are also more open to participating in research.
But the picture is more complex
Other aspects of scientific literacy that we examined include scientific reasoning and understanding of the nature of science—that is, how people think through evidence, evaluate claims, and understand how scientific knowledge is developed, tested, and refined over time.
At first glance, it might seem obvious that people who are stronger in these areas would be more willing to participate in medical research. However, our findings paint a more complex picture.
These aspects were linked to willingness to participate through two different pathways. On the one hand, they were associated with lower endorsement of conspiracy beliefs. This was linked to greater trust in medical researchers and, ultimately, greater willingness to participate. On the other hand, they were also associated with lower trust in medical researchers, which was linked to lower willingness to participate.
One possible explanation is that a deeper understanding of the nature of science and better scientific reasoning can make people more aware of the limitations and uncertainties inherent in science. This may help them reject conspiracy theories, while also making them more critical of researchers. As a result, these aspects of scientific reasoning may have both benefits and unintended consequences for participation in medical research.
What this means for increasing participation
One key message stands out: encouraging participation in medical research is not just about addressing beliefs about medical researchers. Scientific literacy matters as well.
This suggests that efforts to increase participation may work best when they combine three elements: building trust in medical researchers, countering conspiracy beliefs about them, and fostering scientific literacy.
But this needs to be done carefully. As our findings suggest, a better understanding of science and scientific reasoning may come with a clearer awareness of its limitations and uncertainties. For this reason, it is important to emphasize that science is a self-correcting system and one of the most reliable ways we have of understanding the world.
If we get this balance right, we may be able to support both stronger trust in medical researchers and a more scientifically informed public—both of which appear to be linked to people’s willingness to take part in medical research.
