Tone scale

In Scientology, the tone scale or emotional tone scale is a characterization of human behavior. It is based on the idea that some people appear to be more lively and alive than other people; this increased liveliness is orderly. Author L. Ron Hubbard spelled the idea out saying, "just draw a horizontal line on the page. Put the people who are less alive on the bottom and the people who are more alive on the top."
