Baby Shark and The Boxer make it easy to understand the song and lower cognitive load by replacing words with sound. They use “doo doo doos” and “Lie-la-Lie’s” respectively.

These sounds keep the feeling going, while making sure the listener doesn’t have too much to process. More times than not, in communication it’s the feeling that matters anyway. Only 7% of communication is the words we choose.

This presents an opportunity. If you’re making a presentation and showing slides, perhaps you don’t have to explain them all, create a set of rapidly advancing slides that make the point you’ve been leading to without having to explain. This is the presentation equivalent of the repetitive sounds in song. It’s also a bit unusual, so it will create some tension, which is good for a presentation.
