If you speak to groups of people, then this is a proven, simple, communication technique that will allow you to be heard by all people. If you use 8 sentence, then 100% of your audience will hear you. Said another way, you will have 100% of their attention. Your 9th sentence is you Call to Action for them. If you use only 4 of these sentences, then 76% of the audience will hear you. 50 years of science is the proof. This is 100% founded in Myers Briggs. I have been doing this since 2001. I've used it for Keynote speaches, for case study anchor points, executive summaries of proposals and about 9 other things. Another great one is the home page of a website. And, lastly, it's also good to prevent groups from trying to harm your project when they feel it threatens their domain, Regardless, no one else uses this. It's a rare and ultimate competitive advantage you will have. I give you the word triggers for each of the 8sentence types. You simply add you subject matter. The power to communicate and be heard is what you are buying here.
