When people create business content, they often rely on variety to keep an audience engaged. Images, text, shapes, colors, charts, stories, etc., and all of it meant to stimulate. And even though variety works because it gives the brain a buzz, the problem of forgettable content starts to settle in when there is nothing for the variety to anchor in.
Consider each segment in the first shot in the video below as an abstract representation of a slide that is meant to attract attention in a real deck. Because there is so much variety, the brain treats them all as equal strangers. Nothing stands out, because nothing repeats. As the teal circle begins to appear (this is an abstract representation of what I call the 10% message), the brain starts to assign it meaning. Not necessarily because it is the most beautiful (sometimes 10% messages may be bland), but because, with repetition, it becomes familiar. With each appearance, it starts to function like a small gravitational pull. It gives the rest of the content a center. It gives the audience a place to land. Repetition in this case acts like instruction, it teaches the viewer what matters.
The reminder for content creators is to keep your variety, but let one idea, expressed in a distinctive way, return often enough that the brain knows where to focus. In other words, everything can vary except the thing you want them to remember.
