"Cyber Bubble" aims to promote key aspects of digital literacy. We want to focus on the handling of data and information sources so that fake news can be identified and users can be sensitized to the handling of their own and other people's data in their usage behavior. Especially emotionalized people believe devious information more quickly and take little time to reflect on what they have read, but this is exactly what they need to filter information in a factual and truthful manner.
