Cadbury's Cocoa : absolutely pure / Cadbury's.
The pattern
This still is filed under Borrowed medical authority.
Define
The claim wears a lab coat: a diagram, a percentage, a clinical tone that is not necessarily a clinician.
Mechanism
Authority costume. Science-looking form transfers trust. Use it only when the substance matches, or we are documenting a historical mechanism. We do not recommend the abuse.
Verdict
We have real evidence and the buyer needs it in a form they already trust: a chart, a protocol, a named standard.
Why it works
Visually segments the market, providing a specific reason to buy for different family members, making the product a household staple. The back copy provides scientific-sounding justification against competitors.
Steal this when
Your product serves multiple distinct demographics within a single household, and you want to visualize the specific benefit for each.
