The amount of open-source information – that is, data, images, and footage that is openly available to the public - is growing exponentially. With it, so is the number of citizens analysing this data to form open-source intelligence (OSINT). Using the 2022 invasion of Ukraine as a case study, this study highlights the motivations behind the citizen OSINT analysts who are uncovering events on the frontline and verifying significant amounts of data from such events. Through interviews with 10 citizen OSINT analysts – all voluntarily contributing to OSINT in relation to the invasion of Ukraine, as well as other major OSINT projects – this study demonstrates the motivations behind this growing community. The findings reflect a new era of participation and advocacy and are a demonstration of self-determination theory. The findings demonstrate citizens’ sceptic views towards traditional media but also, that with a more analytical approach, with improved transparency and collaboration there is reason to be optimistic about the future of journalism and audience engagement.
