The DECODE project stems from a participatory needs analysis conducted with the youth groups of the partners, coordinated by 6 group leaders, to address online youth radicalization and misinformation. Young people, particularly vulnerable ones, were actively involved in co-writing the project through surveys, focus groups, and online discussions. This process allowed for the identification of common vulnerabilities, such as social isolation and lack of digital skills, and the design of targeted activities to address these challenges. The project aims to promote youth empowerment, intercultural dialogue, and access to European opportunities. The objectives of DECODE are as follows: 1. To counter youth radicalization through intercultural and interreligious dialogue, understanding the values of the European Union, and the value of European citizenship. 2. To develop digital literacy and fact-checking skills to recognize the psycho-emotional harm of radical content and combat the threat to European values, analyzing ICT both for their educational and innovative value, as well as their role as vehicles for psychological manipulation, recruitment of vulnerable youth, and deep fakes. 3. To develop prevention strategies to recognize and counter the risk factors of online youth radicalization, violent extremism, and the normalization of violence. 4. To share best practices in digital safety and personal data protection. 5. To promote civic sense and participation in the European Union and its values. 6. To facilitate access to European opportunities for young people with fewer opportunities. 7. To develop two tangible outputs: a digital documentary project on European belonging and a Decalogue of best practices for fact-checking and debunking extremist ideologies and deep fakes.
