Scientists Not Seen as More Trustworthy Than Other Groups in Public Debates

A recent study has raised questions about the perceived credibility of scientists in public debates, suggesting that their status as experts is not always viewed as superior to others when it comes to issues like health, education and employment.

The research, conducted by teams from the University of Manchester and KTH Royal Institute of Technology in Sweden, involved over 6,000 participants in both countries. These individuals were presented with various statements on societal topics, attributed to different types of experts: academic scientists, businesspeople, government officials, or advocates.

Surprisingly, the findings indicate that while scientists are generally regarded as credible, they are not necessarily seen as more trustworthy than other groups when discussing certain issues. In some cases, their credibility is even lower than that of businesspeople and advocates.

The study's results challenge a long-held assumption that scientific expertise automatically confers greater credibility on academics participating in public debates. This idea has been debated for years, but the new research suggests it may be more complex than previously thought.

The researchers used a survey experiment to gather their data, presenting participants with statements from various experts and asking them to assess the credibility of each individual or group.

The researchers used a survey experiment to gather data on how people perceive credibility in public debates. To test this, they presented participants with statements from various experts on both technological and non-technological issues. This approach allowed them to examine whether the identity of the person making a claim affected how convincing it appeared.

The study involved two nationally representative samples: one from the UK and another from Sweden. Data was collected online, resulting in 6,198 complete responses that were included in the analysis. Each participant assessed eight different combinations of statements and expert types to determine their perceived credibility.

When discussing technological developments and their societal consequences, scientists' credibility increased relative to other expert groups. However, this trend reversed when experts addressed non-technological social issues like health, education, or employment. In these cases, businesspeople and issue advocates were seen as more credible than scientists.

The researchers suggest that people may view scientific expertise differently depending on the topic being discussed. They propose that technology-related questions are seen as areas where scientists possess relevant specialist knowledge. By contrast, wider social questions often involve competing values, political judgments, and forms of knowledge outside academia.

People's perceptions of scientific expertise in public debates are not necessarily aligned with their broader support for science.

When it comes to specific societal issues, many respondents expressed concerns about scientists being influenced by vested interests or ideological biases.

In fact, nearly 37% believed that scientists were swayed by financial interests, while another 37% thought they held certain ideological views, and over a third felt that scientific knowledge was not directly relevant to the social questions at hand.

These forms of distrust appear to be linked to the credibility disadvantage experienced by scientists in public debates, with specific concerns driving the gap between technological and non-technical issues.

People who expressed these concerns about scientists' motives and relevance tended to be more skeptical of their expertise on particular topics.

The study suggests that scientific expertise may not be enough to guarantee credibility in public debates. According to Lawson, this raises broader questions about the evolving relationship between science and society.

This development highlights a shift in expectations from scientists, who are now expected to contribute more than just technical knowledge to public discussions. The findings indicate that people's perceptions of scientists' credibility depend on various factors beyond their expertise.
