Using specific, non-round numbers in claims makes them seem more accurate and credible. Consumers subconsciously associate precision with expertise, whereas round numbers can feel like casual estimations. This effect was demonstrated in a study where a deodorant claim of '47% reduction' was rated as more credible than '50% reduction'.

Humans naturally conserve mental energy, a concept Princeton's Susan Fisk calls being 'cognitive misers.' For most decisions, people default to quick, intuitive rules of thumb (heuristics) rather than deep, logical analysis. Marketing is more effective when it works with this human nature, not against it.

A 1972 study found people remember concrete phrases ("a white horse") four times better than abstract ones ("basic truth"). Brands like Apple and Red Bull use this by translating abstract benefits (memory, energy) into visualizable concepts ("songs in your pocket," "wings") to make their messaging stick.

Our brains favor things that are easy to think about ('processing fluency'), subconsciously misattributing this ease as a positive feeling toward the product itself. Subtle cues like font matter immensely; a slim font for a 'slim' phone can increase purchase intent by 27% simply because the visual aligns with the message.

People lack the attention for complex solutions. A simple, memorable soundbite, like Donald Trump's "Build a wall," will often defeat a comprehensive, nuanced plan, like Jeb Bush's book on immigration. The message with the lowest cognitive load wins, regardless of its substance.

Our brains remember tangible information we can visualize four times better than abstract ideas like 'quality' or 'trust.' Instead of describing MP3 player storage in 'megabytes,' Apple used the concrete, visual phrase '1,000 songs in your pocket,' making the benefit sticky and easy to recall.

Abstract technical specs like "5 gigabytes of storage" are far less memorable than concrete phrases that create a mental image. Research shows people are four times more likely to recall concrete terms (like "white horse") than abstract ones. Effective taglines allow the customer to visualize the benefit.

Instead of making direct, often unbelievable claims about quality or trust, use humor. The positive feeling from being amused creates a 'halo effect' that transfers to all other brand metrics. Ads are a powerful medium for demonstrating wit, which is more effective than claiming hard-to-prove attributes.

Using a precise, non-round number like 5,127 creates an "illusion of effort" and intentionality, making claims more believable than a rounded number like "5,000." This psychological principle suggests that specificity signals thoroughness and purpose, increasing customer trust in the final product's quality.
