The Science Behind Effective Health Communication: Dr. Tesfa Alexander, Lerner Center for Public Health Advocacy at the Johns Hopkins Bloomberg School of Public Health

from Raise the Line · host Dr. Tesfa Alexander, Lindsey Smith

We've had many conversations on Raise the Line about the challenges of health communication in today's world of information overload, but none of our guests have the kind of expertise Dr. Tesfa Alexander has acquired in a career that has taken him from Madison Avenue to the halls of government and academia. From guiding tobacco education research at the FDA to leading public health initiatives at MITRE, Dr. Alexander has developed a deep understanding of the science and strategy behind effective health communication. “Successful campaigns keep the long game in mind where you want to develop a lasting relationship with your target audience,” he tells host Lindsey Smith. That relationship needs to be built on understanding culture, beliefs, priorities and daily realities, and only then can you develop messaging that will resonate, he explains. Dr. Alexander also believes these relationships can be leveraged to help people sort out facts from misleading or inaccurate claims. “I strongly recommend shifting our focus from combating misinformation head on, and instead working with the communities who we are seeking to serve.” This fascinating look at communication science also covers: How stories drive belief; The importance of working with community partners who are trusted messengers; The power of audience segmentation. Tune in as Dr. Alexander unpacks what it takes to influence beliefs, and ultimately behaviors, in an era defined by misinformation and institutional mistrust.
