The latest issue of the Leibniz Association’s magazine focuses on the topic of ‘Medicine’ as part of Science Year 2026. Dr. Claudia Lampert, head of the Health Communication research group at the HBI, discusses health influencers in an interview.
The issue is only available in German and can be downloaded for free here. The interview with Dr Lampert begins on page 19.
For so-called health influencers, social media is a lucrative business. Why do these (often self-proclaimed) health experts resonate so well with young people in particular? And when does trust turn into risk?
Claudia Lampert explains: ‘They use mechanisms that make social media powerful overall: emotional appeal, visual dramatisation and an aesthetic presentation that captures attention. People often come across this content not because they’re actively looking for it, but because it appears in their feed. A jarring image, a dramatic statement or a personal confession — all of this ensures that people get hooked.”
Healthfluencers reach 15- to 25-year-olds in particular. A sense of belonging, self-identification and searching for answers play a major role during this phase of life, says Lampert, who adds: ‘When people appear who seem approachable, describe similar problems, or promise simple solutions, it quickly has an impact.’
The researcher views health-related misinformation as a significant risk. If people blindly trust recommendations, false or misleading information could have serious consequences, especially in the health sector. Added to this are commercial interests, opaque advertising and unrealistic promises of cures. It is particularly problematic when personal experiences, product advertising and supposed expertise become intertwined to the point where they are almost impossible to distinguish from one another. “When dealing with serious illnesses, people are often willing to cling to things that aren’t evidence-based as long as they offer a glimmer of hope,” says Claudia Lampert.

The fact that this idea is saving lives a quarter of a century later is due in no small part to the work of Rüdiger Behr, a biologist at the German Primate Centre – Leibniz Institute for Primate Research.

He is also convinced that this knowledge is particularly important today.
