The audience needs a way into the idea before being asked to admire its complexity.

Complexity is satisfying to the person who built it and disorienting to everyone else. When you know a subject well, the intricate part is the interesting part, so it is tempting to lead with it. But an audience standing outside needs a door before they can appreciate the architecture: one plain sentence, one familiar example, one reason to care. Without that, the sophistication reads as noise, and people conclude the fault is theirs.

Before your next explanation, write the simplest true version in a single sentence and start there. Save the nuance for after they are inside. You lose nothing by being clear first.
