The first victim of war is the truth. During armed conflicts, disinformation is particularly dangerous, and attempts to manipulate public opinion - whether in the form of a suitably limited set of information or even fake news - are to be expected on both sides of an ongoing conflict. During the workshop, participants will learn how to identify and - most importantly - how to verify manipulated and false information present in the public space in connection with the ongoing war in Ukraine. Fact-checking, or fact-checking strategies, will be discussed using specific examples of disinformation from the first two and a half years of the conflict. Participants will also hear about how professional fact-checking organizations work and how their work can be used to reduce the reach of false information.
