Academics’ societal engagement with local, regional, national and global actors can significantly impact the way knowledge is produced. This engagement takes various forms, including citizen science, community-based participatory research, and even commercial research, which involves the emergence of spin-offs and patents. Any of these forms imply the creation of continuous interaction between community members and academics. In Europe, taking the political relevance of the idea of the Knowledge Society, academics have been encouraged to collaborate with society. Nevertheless, the extent to which academics’ societal engagement influences the nature, dissemination, and commercialization of knowledge remains unclear.. To contribute to this discussion, this chapter analyzes the relationship between academics’ societal engagement and the way knowledge is produced and disseminated in three European countries with different levels of academics’ societal engagement, namely Germany, Portugal, and Sweden. The study is based on a quantitative approach. The survey used for this study was part of the Academic Profession in the Knowledge-based Society (APIKS) project. A representative sample of academics employed by doctorate-granting universities was given access to the online survey. By using the publicly accessible official statistics of the higher education sector, the representativeness of the sample was guaranteed by taking into account academic rank, gender, and discipline in the cases of Germany, Portugal, and Sweden. The analysis shows that there are significant national variations in academics’ assessments of the significance of academics’ societal engagement activities, as well as significant variations in the creation and dissemination of information according to the engagement activities that academics participate in.
