This document provides guidance on delivering effective scientific presentations and posters using six key principles: simple, unexpected, concrete, credible, emotional, and stories. It advises finding the core message and prioritizing messages (simple). Grabbing attention with counterintuitive ideas or curiosity gaps (unexpected). Using specific, sensory language and visuals to make ideas concrete and memorable. Providing evidence and relating data to real experiences to establish credibility. Appealing to emotions and self-interest to encourage caring about the message. And using stories to drive action and inspire through simulation and examples. Resources on applying these principles are also referenced.
