The Detail
"A claim feels true the moment it gets specific."
Round numbers feel made up; precise numbers feel measured. '37% faster' is more believable than 'much faster' — even when both are estimates.
Same hack. Three very different choices.
Specific numbers backed by methodology you'll show on request.
Precise-sounding numbers with no source.
Fabricated statistics designed to look researched.
A formula you can steal
Replace [VAGUE CLAIM] with [PRECISE NUMBER] + [TIME FRAME] + [NAMED SOURCE].
Where you've already seen this
- Domino's '30 minutes or it's free' — the most-copied specificity claim ever.
- Hims & Hers' '4 in 5 men saw new hair growth in 6 months'.
- Wise's exchange-rate comparison showing '£3.42 cheaper than your bank'.
On any benefit claim or social-proof number. Specificity costs nothing and almost always raises trust.
When the precise number is invented to seem researched. Made-up specificity is worse than honest vagueness.
