Authored by Postdoctoral Researcher Luigi Marra from the Department of Aerospace Engineering at Universidad Carlos III de Madrid, this presentation argues that a talk is not merely a transfer of content, but a design process aimed at changing what the audience knows, believes, feels, and does. Presented as part of the HumanIC Cohort Based Training 4, the lecture explains how experts can overcome the „curse of knowledge” by using deliberate empathy. It outlines core narrative frameworks—such as And-But-Therefore and Problem-Tension-Resolution—to build tension and clarity. Finally, it emphasizes effective slide design, advocating for visual hierarchy, strong claim-based titles, and minimizing cognitive load to focus attention, reduce effort, and show evidence.
