The following rules are emphasized:*No commercial agenda. Speakers should not promote their own products, books, or businesses or those of a company which employs them. The only exception is where they have specifically been invited to give a powerful product demo, or to describe the ideas in their book, and here the focus should still be on the technology and/or the ideas.*Avoid pseudoscience. TED and TEDx are platforms for showcasing and explaining genuine advances in science, and it's important we retain the respect of the scientific community. Speakers should avoid the misuse of scientific language to make unsubstantiated claims.*No talks with an inflammatory political or religious agenda, nor for polarizing “us vs them” language. We seek to build consensus and provide outside-the-box thinking, not to revisit familiar, unresolvable disputes on these topics.
