Health misinformation: new WHO movement and fact checks

According to the World Health Organization (WHO), the Together for Science and Health movement was launched on 10 November 2026 in connection with the Paris Peace Forum. More than 240 organisations have joined the initiative, launched under the leadership of WHO Director-General Tedros Adhanom Ghebreyesus and French President Emmanuel Macron. Its aim is to strengthen trust in scientific evidence, which also provides an important reference point when assessing health information online.

What does WHO's new initiative aim to achieve?

WHO's announcement identifies three priorities: bringing science and society closer together, incorporating scientific evidence into health decision-making, and improving science communication. The question they share is how research findings can become understandable, usable knowledge. Simply presenting a conclusion is not enough: it must also be clear what it is based on and where its limits lie.

According to a report by the health promotion organisation CRES PACA, the movement also supports health literacy and prevention among the public. In WHO's earlier invitation to join, Sylvie Briand emphasised that scientific progress alone is not enough unless its findings become accessible and trustworthy to people.

The first question: what exactly does the post claim?

When checking health content, it is worth starting with the claim itself. An article describing a possible avenue of research is different from one promising a guaranteed cure. Phrases such as “works for everyone”, “completely risk-free” or “a suppressed cure” make it particularly important to look for the evidence supporting the promise.

Striking language does not in itself prove that content is false, just as a restrained style does not establish its accuracy. It can help to turn the claim into a simple sentence: what outcome does it promise, for whom and under what circumstances? Without answers to these questions, it is difficult to judge what needs checking.

It is worth opening the link too

Rather than accepting the phrase “research proves”, look for a named study that can be traced. Useful questions include whether the original publication's title, author or link is provided, and whether it actually says the same thing as the post citing it. Mentioning the name of a scientific institution does not, on its own, explain how a particular conclusion was reached.

You do not need to understand every technical term in the original material to spot important distinctions. For example, it is worth checking whether it describes a study involving people, a laboratory experiment or a preliminary idea. These categories are not interchangeable: presenting a research possibility is not the same as making a treatment recommendation for people.

As a thought experiment, imagine a post claiming that a substance “could offer a solution to a disease”, while the text it cites only describes a laboratory observation. In this case, checking does not mean conducting a full expert review of the research. The first step is to establish whether the post promises more than the original work supports.

What should you consider when assessing scientific evidence?

Assessing evidence is not simply a matter of whether a study exists. It also matters how the study was conducted, what comparisons were made and what limitations the authors reported. A personal account is a different kind of information from a systematically designed study, so they should not be given equal weight.

It is also useful to distinguish association from cause and effect. If two things occur together, that alone does not mean one causes the other. When reading, it is therefore worth comparing the certainty of the headline with the wording in the text: “an association was found” and “the cause was established” do not mean the same thing.

Acknowledging uncertainty is not necessarily a weakness

Scientific explanations also have room for what we do not yet know. Phrases such as “based on current findings”, “further research is needed” or “applies only to the group studied” can indicate the limits of a conclusion. When checking a claim, it is therefore worth looking not just for a confident answer, but also for the reasoning behind it.

The publication date is another useful reference point. Check when the original information appeared and whether any updates or clarifications have since been published. When an old article is shared again, a separate question is whether the post makes it clear that it is discussing earlier findings.

A short checklist before sharing

One everyday lesson connected to the aims of WHO's initiative is that trust needs to be accompanied by the ability to verify information. The questions below are general pointers, not part of the movement's official checklist. They can help identify which claims need further investigation.

• Who is publishing it? Are the author, institution and relevant field of expertise identified?
• What does it cite? Is the original publication available, or are other posts simply repeating one another?
• Does the headline match the content? Is the conclusion as certain as the headline suggests?
• Who does it apply to? Is it clear which group and circumstances were studied?
• What remains uncertain? Are limitations and unanswered questions presented?
• Is there a sales motive? Is the health information kept separate from advertising for a product or service?

When comparing sources, do not focus solely on the number of websites making the same claim. Check whether they draw on separate evidence or all cite the same original report. If accounts differ, look for the reason: are they discussing different studies, different points in time or simply different interpretations?

The aim is better understanding, not self-diagnosis

Checking sources can help clarify what a piece of health content claims and what it is based on. However, when assessing a particular illness or treatment, general information online cannot replace a professional assessment of an individual's circumstances; this article is not a medical opinion either. Before making a personal health decision, it is worth discussing the claim and its original source with a doctor or pharmacist, and allowing time to check information before sharing it.
