What is a "public thought leader"? Is this something one trains for or gets certified for? Or, did we used to call them celebrities? THere's already a lot of discussion on various scientific topics, you merely have to go where it's occurring. What comes out of these discussions are (mis)used by political and yammering types to prove or disprove a point. These two communities do not and possibly do not wish to understand each other as the words don't mean the same thing. Take "theory". To the general public, it's a guess. However, Newton's theory of gravity guarantees that a good faceplant is gonna hurt. It also keeps the rocks up there from falling or wandering off.
