Yermain is a Colombian humorist. He’s spent his “downtime” bringing people “uptone” through social media and the television station he works for. He’s also been studying Scientology at home—and that’s no joke. There’s much to understand about the Emotional Tone Scale and how to use it to not only raise your own tone, but also to predict the behavior of others.

The Emotional Tone Scale is one of 19 free Scientology online courses based on principles from The Scientology Handbook.
