Public Engagement (PE) activities can actively and continuously involve anyone in our society, regardless of identity or background, particularly those with an interest in or connection to the topic. This aims to enrich the discourse around research topics with lived experience and valuable societal perspectives outside of academia. These contributors can be citizens, experts, NGOs, schools, children, associations, politicians or companies, to name just a few examples. Through PE, researchers, students, professors and representatives of research institutions enter into an equitable exchange with these communities. PE is an English language term that has become established internationally. By focusing on mutual benefit and exchange supporting society-oriented research, PE clearly differs from other forms of science communication. PE describes a field in the German research landscape, the practice of exchange between researchers and the public, and stands for the attitude that research and society benefit from mutual interaction.
