The article discusses the importance of visual communication in public health, particularly through the lens of a digitized collection of HIV/AIDS posters from 1990 to 2004 by Harvard University. It emphasizes the effectiveness of combining visual and textual elements to enhance message retention. Amanda Yarnell, from the Chan Center for Health Communication, explains the need for simplicity in messaging, the power of emotions in communication, and the evolution of ways to engage viewers, moving from phone numbers to QR codes.
A good poster is one point and a feeling: something that the messenger wants you to remember, and then the feeling helps you remember it.
Seeing something and reading something at the same time improves understanding.
Effective messages can be bold, eye-catching, or even provocative.
Too many words and you lose people.
