Microtargeted propaganda by foreign actors: An interdisciplinary exploration (2509.18211v1)

Abstract: This article discusses a problem that has received scant attention in literature: microtargeted propaganda by foreign actors. Microtargeting involves collecting information about people, and using that information to show them targeted political advertisements. Such microtargeting enables advertisers to target ads to specific groups of people, for instance people who visit certain websites, forums, or Facebook groups. This article focuses on one type of microtargeting: microtargeting by foreign actors. For example, Russia has targeted certain groups in the US with ads, aiming to sow discord. Foreign actors could also try to influence European elections, for instance by advertising in favour of a certain political party. Foreign propaganda possibilities existed before microtargeting. This article explores two questions. In what ways, if any, is microtargeted propaganda by foreign actors different from other foreign propaganda? What could lawmakers in Europe do to mitigate the risks of microtargeted propaganda?
