Securitization is a political process through which a phenomenon is framed as a security issue for gaining legitimacy for subsequent political decisions. At the moment, science too is increasingly being securitized. By focusing on recent developments in Europe, this short report reflects upon the political decisions made, their origins and legitimizing arguments, the contradictions that have emerged, and the potential consequences for academic freedom. Although it is still too early to robustly evaluate all potential consequences, a reflection is needed because the securitization process affects the very core of science in democratic societies.
