The Glance Test is a simple but powerful rule for slide design: if your audience can't understand the point of a slide within a few seconds, the slide isn't doing its job.

In this episode, I explain why slides that demand too much reading or decoding cause audiences to stop listening—and how the Glance Test helps protect attention during live presentations. You'll learn how strong, message-driven titles anchor understanding, why visual simplicity matters more than precision, and how to design slides that support your voice rather than compete with it.

The episode also explores the difference between slides meant to be spoken versus read, where detail really belongs, and how passing the Glance Test leads to calmer delivery, clearer pacing, and more persuasive presentations. If your slides feel busy or your audience seems distracted, this episode offers a practical framework to fix both.
