Resumen

Ultimately, all our knowledge about the world comes from observations and measurements. An important part of this knowledge comes directly from observations and measurements. For example, when a person becomes sick, we can measure this person’s body temperature, blood pressure, etc. and, thus, usually get a good understanding of the problem. In addition, a significant part of our knowledge comes from experts who -inspired by previous observations and measurements- supplement the measurement results with their estimates. For example, a skilled medical doctor can supplement the measurement results with his/her experience-based intuition. Measurements exist for several millennia, and many effective techniques have been developed for processing measurement results. In contrast, processing expert opinions is a reasonably new field, with many open problems. A natural idea is thus to see if measurement-related ideas can help us use expert knowledge as well. In this chapter, we provide three case studies where such help turned out to be possible. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
