Medical disinformation is particularly effective because it exploits fundamental psychological mechanisms. The most persuasive messages are those that appeal to emotions—especially fear, uncertainty and a sense of vulnerability. As this report demonstrates, the scale of the problem is considerable, and it is concentrated around deeply personal issues such as vaccination, children’s health and alternative therapies. These are precisely the areas in which people are most receptive to messages that promise safety, simplicity and clear-cut answers.

Equally important is the way these messages are communicated. Medical disinformation is often presented in clear, accessible language and enhanced with features that imitate scientific credibility and professional authority. At the same time, it offers simple, universal solutions—claims that a single remedy “works for everything,” “addresses the root cause,” or provides definitive answers that relieve people of the need to evaluate evidence for themselves. This aligns with well-established principles of human cognition: critically assessing information requires time, effort and relevant knowledge, whereas simplified narratives are often more appealing than nuanced scientific explanations.

Against this backdrop, creating environments where people can engage with science in ways that are both accessible and inspiring becomes increasingly important. This is the vision behind the Medical Discovery Centre being established at Wroclaw Medical University. The Centre is founded on the belief that scientific knowledge can be rigorous, engaging and accessible at the same time. Its mission is to strengthen trust in science while helping visitors develop the skills needed to critically evaluate health information. In this sense, the Medical Discovery Centre is intended to serve as a “vaccine against medical disinformation“—building resilience before misinformation takes hold.
