In Sinclair Lewis's "It Can't Happen Here," the character Berzelius Windrip emphasizes the realities of effective communication, particularly in the realm of propaganda. Windrip believes that a skilled propagandist must recognize the limitations of their audience. Presenting complex truths can overwhelm ordinary people; thus, a more tailored approach is necessary for effective messaging. Understanding the audience's context is critical in ensuring the message resonates without confusing them.

Furthermore, Windrip notes the importance of timing in persuasion. He suggests that engaging with people when they are fatigued, particularly in the evening, can lead to greater receptiveness. This strategic choice allows the propagandist to bypass some of the audience's defenses, making it easier for them to absorb the intended message. This perspective highlights the intricate relationship between communication, audience dynamics, and effective influence.
