In the era of post-facts, fake news and disinformation have become mainstream, influencing societies and electoral turnouts. They adapt to users’ perceptions, reinforcing stereotypes and prejudices. Extremists, foreign forces, and third parties weaponize fake news to manipulate regions, countries, and international organizations. This has led to polarization and decreased trust in mainstream politics and media. Media Literacy Index 2019 reveals a regression in CEE countries, exacerbating the gap and distrust among citizens. The COVID-19 pandemic has further widened this gap, particularly affecting young people in lockdown. Our project aims to debunk social bubbles in the online sphere that divide future generations. Building on previous research, we will develop training for young leaders, community leaders, and public figures to combat fake news and promote true information. We will also create an interactive web application to help young people assess their “bubble vulnerability” and understand its real-life impact. An awareness campaign will be designed and disseminated through the channels of young leaders and their followers.
