Health Misinformation: Introduction
The Covid-19 pandemic illustrates the challenges of science communication and the dangers of unreliable or false health information. How do we communicate about reliable health information in a fluctuating information landscape, where new research is constantly emerging, often with an absence of scientific consensus or to patrons who lack basic scientific understanding or knowledge?
In a world of competing facts and “alternative facts”, it is increasingly important to adopt evidence-based communication strategies to ensure that people hear, and adopt, public health recommendations. People need to know “how information works’” — not just how to find and select information, but to also understand the social contexts that influence how information is created and disseminated.
"Today medical misinformation is recognized as one of the greatest threats to global health. By undermining trust in science and public health interventions, medical misinformation threatens the health of individuals and communities and the effectiveness of public health interventions. "
Historical Health Misinformation
Health misinformation is far from new, as early knowledge about human disease focused on superstition, myths, and religion. The invention of the printing press in 1450 allowed for invented ‘facts’ to circulate widely in Europe. Similar to modern Facebook posts, cheap weekly publications of broadsides like the Lord Have Mercy, appeared during the seventeenth-century Black Death plague outbreaks. In an effort to be helpful they would publish home remedies to help protect from the disease. There were other strangely bizarre cures for the Black Death. A treatment named the Vicary Method involved plucking feathers from a chicken’s rump and then tying the chicken to the patient, so that the chicken’s now bare backside was touching the person’s swollen lymph nodes. The notion behind this interesting cure was that people believed that chickens breathed through their bottoms, so therefore the chicken would draw the infection out of the person.

The Tuskegee Study
For historically marginalized groups, distrust in the health care system looms large in the sharing of health misinformation. The Tuskegee Study is an example of why this exists. In 1932, the Public Health Service, working with the Tuskegee Institute, began the “Tuskegee Study of Untreated Syphilis in the Negro Male”, a medical study on the long term effects of untreated syphilis, that involved 600 Black men, 399 with syphilis and 201 without the disease. The study designers neglected to tell participants that they had syphilis and did not allow those patients who did have syphilis to receive proper treatment, only placebos. Many participants died from complications of syphilis and many wives, girlfriends and children contracted the disease.

Types of Health Misinformation
- False information that is considered incorrect based on the best available evidence from relevant experts at the time and is spread, regardless of intent to mislead. It can be unintentional mistakes such as inaccurate captions, dates, statistics or translations or when satire is taken seriously.
- Deliberately fabricated or manipulated false information. Often intentionally created to trick people into believing something for financial gain or political advantage or support conspiracy theories or rumors.
- Malinformation is information that is based on the truth but is often exaggerated in a way that misleads and causes potential harm. It can be the deliberate change of context, date or time of genuine content or the revealing of private information publicly.
- Misunderstandings and confusion based on scant or emerging evidence, often about emerging scientific knowledge. It is usually based on knowledge gaps that can be filled with inaccurate or even dated information.

Psychology of Misinformation
Those who spread misinformation are driven by many sociopsychological factors.
We may not be able to fully understand why someone shares or creates harmful information. Their intentions can be mixed, unclear, and even change over time. Human psychology and sociocultural factors leave people highly vulnerable to accepting and spreading false health information. In addition, technological advances such as the internet, social media and smart phones, have fostered an age where misinformation can be widely accessed and shared.
Cognitive biases and disordered thinking can make people more susceptible to misinformation.
Disordered thinking, or cognitive distortions, are negative biases in thinking that are thought to represent vulnerability factors. A cognitive distortion is an exaggerated pattern of thought or biased perspectives that’s not based on facts. It consequently leads the person to view things more negatively than they really are. So cognitive distortions is the mind convincing you to believe negative things about yourself and your world that are not necessarily true. When negative thoughts are treated as facts, people may act in a way based on faulty assumptions.
Cognitive bias refers to a systematic error in the thinking process. Such biases are essentially mental shortcuts, which allow people to make an inference about the credibility of a source of information without extensive deliberation and/or reflective judgment. Biases often work as rules of thumb that help people make sense of the world and reach decisions with relative speed.

Common Types of Misinformation Venues or Tactics
Some common types of misinformation tactics
Websites that look professional: they are often designed to look like news/medical sites but the stories are all false or misleading. They have sensational headlines designed to make us click on them. They will often Include the logo of an established organization, like the CDC or a news network logo;
Quotations: Where the beginning or end have been deleted to change the meaning. The person did say that, but without the full context it’s not a fair representation of what they said. People who spread disinformation may create content that looks like a first person experience. It’s very difficult to “fact-check” someone who says, “This happened to me.” or “My brother works for the government and has inside knowledge. He just told me that…” or “My sister is a nurse and just called me from the ICU to tell me…”
- Old images: that recirculate as if they are actually very recent but were actually taken at a different time.
- Misleading graphs, images or diagrams: that look official but don’t tell the whole story (see cherry-picked statistics) or they use visual cues like someone wearing a white coat, holding a stethoscope, at a hospital bed-side;
- Cherry-picked statistics: Too often people choose the number(s) that supports what they want to argue, but without all the data, they haven’t provided all the context.
- Videos: that have been edited to change the meaning, including "deep fakes"
- Memes: (fun, colorful images or graphics) that were created as a joke, but people started re-sharing thinking it was true.
Propaganda, a misinformation tactic, is nearly as old as human civilization. Propaganda is defined as a communication whose purpose is to influence the attitudes of a community or a group of people for a cause or position. The basic purpose of propaganda is to persuade people by providing distorting information. Most of the time, propaganda is biased and its sole purpose is to inspire people to accept a particular viewpoint. Unfortunately, public health campaigns can inspire propaganda backlash.

Fallacies of Logic
Another misinformation tactic is to use logical fallacies, which share many similarities to cognitive biases. Logical fallacies are very common patterns of reasoning that seem true on the surface but have one or more critical flaws. They are super normal and everyone uses them. Many logical fallacies, at their root, are oversimplifications – like cognitive shortcuts. They are appealing because they take something complex, like vaccine safety or the efficacy of masks, and convert it into something simple and easy to understand. This oversimplification however, often leaves out important details, leading to the inaccurate conclusions. When someone uses a fallacy in their argument, it doesn’t automatically mean they’re wrong or stupid, it simply means that they haven’t provided adequate evidence supporting their argument – evidence which may or may not exist.
Fallacies: Internet Encyclopedia of Philosophy
Techniques of Science Denial
John Cook of Skeptical Science.com has been dealing for a long time with disinformation on climate change. He developed a framework of the five most common methods of science denial and called it the Techniques of Science Denial or FLICC which stands: Fake experts, Logical fallacies, Impossible expectations, Cherry picking, and Conspiracy theories.

Critically Evaluating Information
Teaching people to critically evaluate the accuracy of information and sources can reduce the influence of misinformation and the likelihood that people will share misinformation.
There is emerging evidence that it is possible to pre-emptively debunk, or pre-bunk, misinformation before false beliefs or ways of thinking have a chance to take hold. People can be ‘inoculated’ against misinformation.
There are many reliable fact-checking groups such as the Associated Press, Reuters, USA Today, the Washington Post, PolitiFact, and FactCheck.org, including ones that focus especially on health information, such as ScienceUpFirst, iHealthFacts (Ireland), Health Feedback.org (France) and Retraction Watch. These sites attempt to verify scientific or health claims in the media by contacting subject matter experts who provide credible references to recently published, credible scientific literature that supports their analyses.
Fact Checking Sites
- FactCheck.org: From the Annenberg Public Policy Center of the University of Pennsylvania, this is a nonprofit, nonpartisan site dedicated to reducing the level of deception and confusion in U.S. politics.
- SciCheck.org From FactCheck.org it focuses exclusively on false and misleading scientific claims that are made by partisans to influence public policy.

- Retraction Watch: Reports on retractions of peer-reviewed scientific journal articles.
- Health Feedback: Health Feedback is a worldwide network of scientists sorting fact from fiction in health and medical media coverage
The National Academy of Medicine held a forum in 2021 on identifying credible sources of health information and came up with a set of principles for sources providing health information:
- Science-Based: Sources should provide information that is consistent with the best scientific evidence available at the time and meet standards for the creation, review, and presentation of scientific content.
- Objective: Sources should take steps to reduce the influence of financial and other forms of conflict of interest (COI) or bias that might compromise or be perceived to compromise the quality of the information they provide.
- Transparent and Accountable: Sources should disclose the limitations of the information they provide, as well as conflicts of interest, content errors, or procedural missteps. At the frontiers of understanding, scientific knowledge changes over time as more evidence becomes available and as existing evidence is analyzed in new ways. … To maintain credibility, sources must clearly acknowledge the limitations of the information they share so that consumers can reach fully informed conclusions.
