Laws of Persuasion Physics
Specificity Breeds Credibility
Details create trust.
Specific details make you believable. Vague claims make you forgettable. "We helped 147 brands increase ROAS by an average of 2.3x" lands differently than "We help brands get better results." The specific version might even be less impressive — but it's infinitely more credible.
Why This Works
The brain uses detail as a proxy for truth. Cognitive scientists call this the "detail heuristic" — specific information is harder to fabricate, so the brain treats it as more likely to be genuine. Vague claims activate the skepticism filter. Specific claims bypass it. It's not about the size of the number — it's about the precision.
In Your Ads
Find every vague claim in your ad and make it specific. "Fast results" becomes "results in 11 days." "Lots of brands trust us" becomes "used by 2,847 D2C brands." "Better performance" becomes "34% lower CPA." You don't need bigger numbers. You need precise ones.
When This Breaks
Your ad says "amazing results" and "incredible growth" and the viewer's brain files it in the same folder as every other ad that says the same thing.
Example
Vague: "Our clients see great ROI." Specific: "Our average client sees a 2.7x return within the first 23 days."
