Dr. Susanne Moser, a natural scientist, social scientist, and communicator with the National Center for Atmospheric Research, explores communication and social change, discussing such ideas as the information deficit model of communication, the social tipping point, barriers to action, and the development of positive myths and narratives. Says Moser, “The reason I think social science would be really, really helpful for communicators is that it allows us to actually be effective. To actually achieve what I assume communications can achieve. Theories and practices of communication have evolved over time. We ought to stay up with that. . . .”
