How do you know if a health information source is reliable?
In today's world, information travels fast, aided by mass media and social media dissemination. This means that health advice is at our fingertips but it can also mean that we may imbibe inaccurate health information if we are not careful.
Maria Cohut - Recent surveys and analyses suggest that our society is vulnerable to absorbing misinformation, including health misinformation, particularly through social media dissemination. In this context, how can we tell if we can trust a source of health information, and what can we do to protect ourselves against inaccurate health advice?
According to a consumer survey conducted by Healthline in 2024, among respondents in the United States, more than half reported they gathered health information via social media, and 32% said they relied on family, friends, and colleagues for health advice.
Yet, despite admitting to relying heavily on social media for information, respondents also overwhelmingly indicated that they did not fully trust the accuracy of these sources.
In the United Kingdom, a nationally representative survey conducted by The Alan Turing Institute in 2024 found that 94% of the population had reportedly witnessed misinformation circulating on social media.
But how can we know if what we are looking at is an accurate piece of information or not? How can we verify our sources of health information? To find out more, Medical News Today spoke with Dawn Holford, PhD, a research fellow in the School of Psychological Science at the University of Bristol, U.K.
Holford is a behavioral science researcher who specializes in the psychology of communication and decision-making, and she has studied strategies for the prevention and rebuttal of health misinformation.
Why do we ‘fall’ for health misinformation?
To better understand why we might fall for health misinformation in our quest for help and advice, we should look at our “attitude roots,” Holford told us.
This concept was coined by psychologist Matthew Hornsey, and it refers to the beliefs and ideas of the world that we have consolidated within our minds since we were young.
“Attitude roots are part of our psychology, and they can be beliefs, worldviews, emotions — basically, they are motivational drivers of how we process information,” explained Holford.
These “roots” can also include emotions like anxiety about something whose mechanics we do not really understand, including invasive medical exams, medications, and vaccines.
The expert further noted that general anxiety about going to the doctor and undergoing medical procedures could render us more likely to pick up misinformation that might consolidate that fear.
While this may appear unintuitive — why should we want to continue to feel anxious about something? — it is, in reality, consistent with how our brains work.
Research has shown that humans are very much prone to confirmation bias — we like to selectively look for evidence in support of already-held beliefs and anxieties — and, further, this confirmation bias is a tendency so strong that it can be really hard to dislodge.
However, said Holford: “Attitude roots aren’t bad or good in themselves. They are simply our motivators, shaped by our life experiences and thinking patterns. It’s how they interact with the information environment that might lead to believing in misinformation.”
Who is most susceptible to misinformation?
What, then, is the greatest risk factor when it comes to picking up misinformation? Who is most susceptible to taking inaccurate health information as fact, and why?
Once again, Holford told us that “there is wider research looking at this issue of susceptibility, and this finds that people tend to believe information more if that information aligns with their ideology.”
Yet she also added that certain psychological traits may render us either more or less susceptible to assimilating misinformation.
For instance, Holford said a person’s “willingness to consider different perspectives and evidence, known as ‘actively open-minded thinking’,” is associated with lower susceptibility to misinformation.
Why might people mistrust health info from official sources?
Holford also emphasized that some of the anxieties that make people susceptible to misinformation and even to disinformation — fake information spread with malicious intent by bad actors — arise from real-life negative experiences within the health system.
“To give some examples, we would be more susceptible [to] disinformation that vaccines were intended as a foreign plot to sterilize people like us if we’d had previous experiences — most of the time legitimate! — that shaped our attitude root of distrust of, say, colonial governments,” she pointed out.
Experiences of racism in healthcare, being denied timely treatment due to gender bias, or just overall poor experiences within institutional spaces could all amplify a person’s anxieties and contribute to their susceptibility to inaccurate or downright false health information.
At the same time, Holford explained, “We might be less susceptible to a disinformation narrative that plays into one’s love of all things natural if we don’t really care about that.”
“Often, these narratives can be crafted in overlapping ways so they could target two groups at once, but it’s helpful to think about which attitude root is the target in a piece of misinformation,” she continued.
Where to look for accurate, trustworthy health information
In an age when many people are increasingly losing trust in governmental public health organizations, the question that arises is: Where can we look for the best, most trustworthy health information communicated in an accessible manner?
Trust, Holford emphasized, “is key to everything” when it comes to information and misinformation.
“Ironically, governmental public health organizations are often the places where the information is reliable — because they are accountable to citizens in a way that other content generators would not be,” she pointed out. “Many also make an effort to share information using accessible language.”
“And because health is a pretty broad area, it’s often governmental organizations that have the remit and the wherewithal to coordinate the expertise required to check information,” added Holford.
However, she acknowledged that “there are cases when we don’t feel able to trust our own governments.” - Source: MedicalNewsToday
