The project Truth or Lie: Recognising Online Manipulation was developed in response to clearly identified needs of young people in today’s digital society, where the volume of information, disinformation, and manipulated content is rapidly increasing, while the ability to critically assess such content often does not keep pace. Young people experience a significant part of their social, educational, and political lives through the internet and social media, yet they often lack concrete knowledge and tools to verify the credibility of information, recognise fake news, manipulated images, and “deepfake” content. This gap has direct consequences for democratic participation, public opinion formation, the rise of hate speech, and the spread of stereotypes and distrust in institutions. Our partner organisations observed growing confusion among young people regarding the reliability of online sources and recognised the need to empower them for active and responsible engagement in the digital environment. At EU level, disinformation represents a shared challenge that transcends national borders and affects the quality of democratic processes and institutions. For this reason, an international youth exchange was identified as an appropriate framework for shared learning, exchange of perspectives, and development of transferable competencies across different social and cultural contexts. The project aimed to strengthen digital and media literacy, develop critical thinking, and empower participants to act responsibly and ethically online. Participants gained practical knowledge in identifying manipulated content, understanding the societal impact of disinformation, and reflecting on their own role in shaping the digital space. Creative expression and the use of digital tools were central elements, enabling young people to become active multipliers of knowledge in their local communities. The objectives were fully achieved. Through non-formal learning, practical workshops, and creative processes, participants showed clear progress in understanding online manipulation and increased confidence in verifying sources and analysing digital content. During implementation, discussions on the impact of disinformation on democratic processes were further deepened in response to participants’ interests, representing a qualitative enhancement of the original plan. A key added value of the project was the public exhibition of participants’ work. Initially planned as the final outcome of the exchange, it exceeded the original scope due to strong interest and relevance of the topic. The exhibition has been, and will continue to be, presented in various environments and communities, reaching broader audiences and strengthening long-term awareness of online manipulation. The project aligns with the EU Youth Goals related to informed and democratic societies, youth participation, and digital competence development. Through international cooperation and joint reflection, participants developed intercultural understanding and awareness that digital challenges require cross-border solutions. Special attention was given to the inclusion of young people with fewer opportunities, enriching the diversity of perspectives within the group. Environmental responsibility was promoted through awareness of green travel and responsible resource use, while youth participation was ensured through active co-creation, shared decision-making, and reflection throughout the learning process. The project promoted European values such as democracy, human rights, equality, and non-discrimination, equipping participants with knowledge and competencies for responsible engagement in digital society. It generated added value for participants, strengthened international cooperation among organisations, and actively involved the wider community through the exhibition and online dissemination, demonstrating clear European added value through intercultural learning and joint responses to shared challenges across the EU.
