By: Chip Heath


In ‘Making Numbers Count’, Chip Heath and Karla Starr demystify the world of numbers by discussing the limitations of the human brain in comprehending large or complex numerical data. This book acknowledges that most people struggle to understand and contextualize numerical information, and offers engaging solutions that transform complex data into relatable, digestible narratives. The authors provide an array of techniques, analogies, and comparisons for translating numbers into insightful stories that can be remembered and utilized effectively. By using these methods, readers can improve their decision-making abilities, as well as their understanding and communication of numbers in various contexts.

Numbers Made Simple

Stanford Business School professor Chip Heath and Karla Starr’s book highlights our innate inability to understand numbers. However, the authors reveal that through analogies, comparisons, and conversions, anyone can understand numeric information quickly. With lots of fun and practical examples, their book offers sound principles that will improve readers’ ability to understand and convey numeric data in today’s increasingly number-based world.

Number Savvy

The book highlights how the human brain can recognize up to five objects without counting them, but struggles to perceive larger numbers. The authors propose techniques to improve numerical understanding and decision-making skills. They argue that every complex number can be translated into something easily remembered, used, and discussed.

The Power of Convincing Comparisons

Translating complex numbers into relatable scenarios strengthens people’s memory retention. The most persuasive way of conveying numbers is by crafting messages that render them unnecessary. A prime example is the comparison between white job applicants with a felony conviction and black job applicants without one in the US, which highlights racial inequality with more impact than statistics would.

Simplify Large Numbers

The size of large numbers can be overwhelming and difficult to comprehend. Instead of using figures, it is better to convert them into relatable examples. For instance, one million seconds is equal to 12 days while one billion seconds is equal to 32 years. By simplifying large numbers, information can be communicated more effectively and accurately.

The Power of Simple Numbers

Uncomplicated numbers are more memorable, as opposed to complex and unfriendly numbers such as fractions or lengthy decimals. In practice, customers at A&W mistakenly thought the 1/3-pound burger was smaller in comparison to McDonald’s 1/4-pounder. It’s advisable to use concrete numbers while avoiding rounding off complex numbers to create a lasting impression.

Symbolizing Social Distancing

Nations worldwide have been using various objects as symbols to represent COVID-19 social distancing guidelines. Canada has opted for a hockey stick, France has selected two baguettes, and California has decided on a surfboard. The importance of clear communication is highlighted by doctors, who use common fruit names to describe tumor sizes rather than technical terms. This approach ensures that people can understand numbers more readily, rather than simply reading them. The book emphasizes the significance of speaking directly and communicating effectively to ensure that important information is conveyed accurately and easily.
