Whether it is about the health impact of red wine, the right amount of vitamin D, or if you should be a vegetarian or a pescatarian, information from different sources can be inconsistent. While some of these conflicts are caused by “fake news” spread by non-experts, sometimes conflicting information results from actual scientific disagreement.

This project aims to understand better why expert disagreement exists and what such disagreement does to the public understanding of science. A better grip on the underlying processes of how people view expert disagreement and navigate conflicts may then allow us to detect through which determinants we can alter this behaviour.


In a first step, we try to answer the questions “Why there can be disagreement in science” and “how experts can disagree”. A taxonomy of types and causes for expert disagreement gives an overview of the possible reasons why and how experts may disagree.

In a second step, the project aims to investigate if there is a way to explain and predict how people handle conflicting information? What are the determinants that influence this behaviour?

A third step then aims to experimentally investigate if it is possible to alter/influence/manipulate (one of) these determinants so that people are better prepared to handle conflict/disagreement

Do you sometimes feel confused after reading all the mixed messages about which foods, diets, supplements and eating behaviours are good for you and which are bad?
