Scientific advertising is the application of the scientific method to the art of persuasion. It replaces "cleverness" with "traced results." By using Claude Hopkins' testing rigor, David Ogilvy's brand-building "Big Idea," and Josh Kaufman's business mental models, it ensures that every line of copy is a super-salesman that justifies its own cost.

The only purpose of advertising is to make sales. Treat every advertisement as a super-salesman. If you wouldn't say it to a prospect face-to-face, don't write it in an ad. Never seek applause; only seek action.
Unless your advertising contains a "Big Idea," it will pass like a ship in the night. The Big Idea is the unique, arresting angle that hooks the reader's attention and makes the brand memorable for the long term.
All marketing should tap into one of the five core human drives:
Generalities like "best quality" are ignored. Specific claims like "softens beards in 78 seconds" or "used by 52 nations" imply evidence and are accepted as truth. The more facts you tell, the more you sell.
"She is your wife." Never talk down to the reader. Provide intelligent, research-based evidence. Use long copy if the product requires it; people interested in buying will read a volume if it is informative.
Never start an ad without researching the product and the consumer. Identify the "Problem" the consumer has and the "Secret" your product offers. Use interviews or surveys to find the "Responsive Chords."
Find the hook. What makes this product unique?
The headline is 80% of the ad's value.
Provide the logical justification for the purchase.
Give explicit, simple instructions on what to do next. Use a coupon or a unique URL to trace the return. Every ad must be a test.
No amount of advertising can create value where there is no market. First, ensure there is a group of people who want the product and have the means to buy it.
REQUIRED SUB-SKILL: resonance-engine — to ensure the hook has emotional weight. RECOMMENDED SUB-SKILL: copy-editor — to prune the ad until every word "tells."
