This study examines how individuals’ exposure to ISIS-related propaganda affects public sympathy for ISIS. We examine the extent that each type of communication channel (e.g. online media, traditional offline media, and in-person interactions) affects an individual’s perceptions of ISIS. We use a nationally representative sample (N = 1,609) from Turkey, which has played an important role during the rise and fall of ISIS with its unique geographical, social, and political position. The findings suggest a significant relationship between exposure to in-person propaganda and having sympathy for ISIS. However, this relationship does not exist for online and traditional media propaganda.
