The current study explores the degree to which two-way communication is applied in science communication contexts in North America, based on the experiences of science communication trainers. Interviews with 24 science communication trainers suggest that scientists rarely focus on applying two-way communication tactics, such as listening to their audiences or tailoring messages based on their audiences' needs. Also, although trainers generally recognize the value of two-way communication, it is seldom addressed in science communication trainings. The importance of two-way communication in fostering interactive dialogical communication between scientists and the public, and thus the importance of emphasizing it more during science communication training, is discussed.
