This discussion paper focuses on how trust in expertise is placed or refused, highlights the affective dimension of epistemic trust, and discusses the danger of a ‘context collapse’ in digital communication. Experts from academies across Europe reflect on the current situation in which expertise and particularly research and science operate in societies today, and what has changed in relation to trust and trustworthiness.

The paper addresses current discussions on the so-called “post-truth” era and draws attention to the questions of placing and refusing trust in expertise, and how expertise and scientific evidence are being contested in a changing landscape of communication.
