1,001 SELLS MORE THAN 1,000

Summary from the TLDR Marketing newsletter

Marketers can increase consumer interest by using numbers that slightly exceed familiar boundaries. Across nine experiments with 2,081 participants, people were willing to pay 219.5% more for a watch limited to 1,001 units versus 1,000, and a book titled "1,001 Places" saw 33% more selections than "1,000 Places." The effect draws attention and increases desire but weakens with larger deviations or when paired with other persuasive tactics. It does not work for pricing or when used in combination with tactics like social proof.
