People still trust scientists: Aston University psychologists contribute to largest post-pandemic study on public trust

• Researchers looked at trust in scientists in 68 countries and found relatively high levels of trust everywhere
• The TISP Many Labs study of 71,922 people included those living in under-researched nations of the Global South
• The majority of survey participants believe that scientists should be more involved in society and policymaking.

Public trust in scientists is still high, according to a survey carried out in 68 countries by an international team of 241 researchers, led by Dr Viktoria Cologna (Harvard University, ETH Zurich) and Dr Niels Mede (University of Zurich).

The study found no evidence of the oft-repeated claim of a crisis of trust in science. The team, which included Aston University School of Psychology’s Dr James Reynolds and Dr Charlotte Pennington, also found that the majority of survey participants believed that scientists should be more involved in society and policymaking.

This study is the result of the Trust in Science and Science-Related Populism (TISP) Many Labs study, a collaborative effort that allowed the authors to survey 71,922 people in 68 countries, including many under-researched countries in the ‘Global South’.

For the first time since the COVID-19 pandemic, the study provides global, representative survey data on the populations and regions of the world in which researchers are perceived to be most trustworthy, the extent to which they should engage with the public and whether science is prioritising important research issues.

Dr Mede said:

“The study is the most comprehensive post-pandemic snapshot of trust in scientists, societal expectations of their involvement in society and policymaking and public views on research priorities.”

Across 68 countries, the study finds that the majority of the public has a relatively high level of trust in scientists (mean trust level = 3.62, on a scale of 1 = very low trust to 5 = very high trust). The majority of respondents also perceive scientists as qualified (78%), honest (57%) and concerned about people’s wellbeing (56%).

However, the results also reveal some areas of concern. Globally, less than half of respondents (42%) believe that scientists pay attention to the views of others. Additionally, many people felt that the priorities of science are not always well-aligned with their own priorities. The researchers call upon scientists to take the results seriously and find ways to be more receptive to feedback and more open to dialogue.

The findings confirm the results of previous studies that show significant differences between countries and population groups. In particular, people with right-wing political views in Western countries tend to have less trust in scientists than those with left-wing views. This suggests that attitudes toward science tend to polarise along political lines. In most countries, however, political orientation and trust in scientists were not related.

A majority of respondents want science to play an active role in society and policymaking. Globally, 83% of respondents believe that scientists should communicate with the public about science, providing an impetus for increased science communication efforts. Only a minority (23%) believe that scientists should not actively advocate for specific policies. 52% believe that scientists should be more involved in the policymaking process.

Participants gave high priority to research to improve public health, solve energy problems and reduce poverty. On the other hand, research to develop defence and military technology was given a lower priority. In fact, participants explicitly believe that science is prioritising the development of defence and military technology more than they would like, highlighting a potential misalignment between public and scientific priorities.

Dr Cologna said:

“Our results show that most people in most countries have relatively high trust in scientists and want them to play an active role in society and policymaking”.

Dr Reynolds, a senior lecturer at Aston University School of Psychology, said:

“This research demonstrates that people from all around the globe still have high trust in science and want scientists involved in policymaking. When we face great challenges, such as threats to public health or energy crises, the public recognise the importance that scientists can play and want us involved. This is also true of the UK where levels of public trust in science is one of the highest globally.”

Dr Pennington, a senior lecturer at Aston University School of Psychology, said:

“This project showcases the importance and power of big team science to answer fundamental questions about human behaviour. By pooling our expertise and resources, we were able to reach over 70,000 people and improve sample diversity and representation by recruiting from 68 countries. Overall, the study resulted in an optimistic finding – that people generally trust scientists and agree that they should engage more in society and policymaking. Such trust is important because it allows people to make research-informed decisions about their own lives.”
