Is there a lesson in ISIS’s tactics that can redefine our approach to the disinformation crisis? In this thought-provoking TED Talk, we explore the unexpected parallels between counter-terrorism and our battle against disinformation. Discover why treating societal issues as wars may be our biggest mistake. Inês Narciso has a master's degree in Criminology from the University of Leicester and is a PhD candidate in Sociology at ISCTE-IUL. She specialises in OSINT and in the areas of disinformation and influence operations. She participates in various international working groups in these areas, namely the Code of Practice for Disinformation (CoP), led by the European Commission, the FIMI-ISAC founded supported by European External Action Service and the Partnership for Countering Influence Operations of the Carnegie Endowment for International Peace. She is also one of the authors of the Obsint Guidelines, which try to bring digital research practices in Osint closer to the ethical commitments and methodological rigour of digital methodologies. She is an active volunteer for VOST Europe, an organisation of digital volunteers, through which she sits on the CoP and is on the board of the FIMI ISAC. She has worked as a Technical Expert and Deputy in the XXII and XXIII portuguese governments.
