What are some examples of successful public speakers who have effectively used the strategies outlined in this paragraph?

The theories presented in The Official TED Guide to Public Speaking challenge existing paradigms or practices in public speaking by emphasizing authenticity and storytelling over traditional methods of persuasion. The guide discourages speakers from trying to be someone they're not, name-dropping, boasting, or making the talk all about themselves. Instead, it encourages speakers to tell a story, either to open the talk or to illustrate the middle part of it. It also advises speakers to avoid tribal thinking, such as political or religious references, that can alienate parts of the audience.

Tribal thinking, as explained in the book 'The Official TED Guide to Public Speaking', refers to the tendency to make political or religious references that can potentially alienate or turn off parts of your audience. It's a form of thinking that categorizes people into groups or 'tribes', often leading to division and misunderstanding. The book advises against this kind of thinking when delivering a public speech. Instead, it encourages speakers to connect with their audience on a universal level, avoiding references that could be divisive or controversial.
