Short story about political speeches [duplicate]

Question

• Media: Short story
• When: I read this in school back in the 90's so I assume it is by a well known Sci-Fi author
• Plot: A man is explaining to another about his new scientific process of delivering political speeches. He explains that it's not so much what's in the speech but how the speech is delivered. They make a wager and pick some random person to deliver a speech with no real meaning. The scientist writes the speech and practices with the man for a day or so to get the exact right tone of voice and pitch on certain key words. When the man delivers the speech the audience is worked up into great excitement, cheering for the man. The scientist comes to the realization of how dangerous a discovery this is.
• Setting: Don't remember
• Characters: Main characters where a scientist and his friend but I don't remember names.
• Language: English
• Target Audience: I suppose teenage-adult? No profanity or anything just a shocking realization at the end which requires some understanding of politics/society.

Thinking this must be a Ray Bradbury story I have done some googling but could not find it.

Isaac Asimov, "Ignition Point!" (1981)

Available in Asimov's collection The Winds of Change and Other Stories (1983). A limited number of copies of this book are available to borrow from The Internet Archive.

The ISFDB has the complete list of publications containing "Ignition Point!".

"Every crowd has its ignition point"

"[S]peakers have their ignition point, too."

"Ignition Point!" gives us a company of the future whose computer can write speeches guaranteed to "ignite" any audience.

— Review by s.ferber on amazon.ca

Throwing Out the Script: "Ignition Point!" is about a man who figures out how to write carefully constructed content-free speeches that will get audiences fired up. In the first test, the speechwriter stops in the middle, throws away the speech, and starts improvising -- the speech worked on him, too.

Answer 2

"The Snowball Effect" by Katherine MacLean, originally published in Galaxy in September 1952.

The president of a small college is in the midst of a fiscal crisis and, in attempts to cut his budget, he insists that the head of the Sociology Department justify “what is sociology good for?” This sets off a chain of events in which the department head devises an experiment in institutional growth in which the two men find a small sewing club in an equally-small town and set up conditions by which the club’s membership will grow larger and larger until it reaches the saturation point and the club crumbles on its own unwieldy size. The latter, however, doesn't happen, and the sewing club is on the path to becoming a world government.
