Do numbers in content marketing confuse or lose your audience? 

Book review: Making Numbers Count

Marketers use lots of numbers in our content. The problem is: many people in our audience don’t understand these numbers. 

For example, when McDonalds introduced the Quarter Pounder in the 1980s, competitor A&W responded with a bigger 1/3 pound burger for the same price. 

A&W’s 1/3 pound burger launch failed miserably. 

Why? Because people thought that 1/4 pound was bigger than 1/3 pound. 

Decades later, A&W relaunched the same size burger but renamed it – the 3/9 pound burger. 

Sounds bigger than 1/3, eh?

A&W 3/9 pound burger
Decades after failing with a 1/3 pound burger, A&W introduced its 3/9 pound burger.

The upshot: fractions are dangerous because many people don’t understand them. 

This lesson comes from a great new book, Making Numbers Count, by Chip Heath and Karla Starr. The book provides communicators with a toolkit for how to make numbers easier to understand.

It turns out that human brains are geared to process whole numbers like 1, 2, 3, 4, 5. Beyond that, people in several cultures use the word “many” to describe quantities. 

“We lose information when we don’t translate numbers into instinctive human experience,” the authors say. 

“The bigger the numbers get, the less sensitive we get to them, phenomenon psychologists have labeled ‘psychophysical numbing’.”

But there’s hope for communicators. “Almost every gnarly number has something – an analogy, a comparison, another dimension – that will allow us to translate it into something we can remember, use, and discuss with others.”

Book, Making Numbers Count
The new book Making Numbers Count helps you find ways to make numbers more understandable for your audiences.

Here are 4 ideas from the book that you can use to make numbers easier to understand:

1. Add a perspective phrase

An example from the book: Pakistan is 340,000 square miles.

To add perspective, say, “That’s about the size of 2 Californias.” 

I bet you can see how big Pakistan is now. So can your audience. 

Instead of using numbers that exclude people from a conversation, invite them in. 

Another example: how much freshwater is on earth?

A scientist could tell you that 97.5% of Earth’s water is salty. Of the 2.5% that is freshwater, more than 99% of it is in the form of glaciers and snow. So only 0.025% of water is drinkable by humans and animals.

That’s hard to size up.

Instead, for an audience of laypersons, say, “Imagine a gallon jug filled with water with 3 ice cubes next to it. All the water in the jug is saltwater. The ice cubes are the only freshwater, and humans or animals can drink only the drops that are melting off of each.”

2. Choose whole numbers in content marketing

Avoid fractions, as the A&W example demonstrates. 

Avoid percentages because they’re confusing. Many people don’t understand “33% of people.” 

Instead, paint word pictures for your audience — say “1 out of 3 people.” 

Round numbers off. Does your audience really need to know that there are exactly 4,981,243? Instead, write “almost 5 million.”

3. Use concrete words on a human scale

A farmer might tell you that 8.33% of the eggs his chicken lays are rotten. It’s hard to picture that.

To make it simpler, instead, the farmer could say that one out of a dozen eggs is rotten. By converting the number to a human scale, you make it easier to understand.

Here’s another example: Try to imagine how much Amazon founder Jeff Bezos is worth. 

In 2020, Bezos’ fortune grew to $75 billion. To most of us, that much money is unfathomable.

To make it understandable, convert it to a human-scaled amount, say $25,000. How much would your life change if someone handed you an extra $25,000 right now?

$25,000 is how much Jeff Bezos makes every 11 seconds. 

4. Speak your audience’s language

While simple numbers are usually better, it’s crucial to speak your audience’s language. Always put this guideline first.

Use units of measure that your audience knows: 

  • Americans weigh in pounds. Most people weigh in kilos. 
  • Shoppers are used to sales with prices of 25% off.
  • Chefs are used to fractions such as 1/2 cup, 1/3 cup, 1/4 cup – so don’t take that away from them.
  • Baseball fans love batting averages, expressed as three-digit decimals such as .333. 
  • Lincoln said, “Four score and seven years ago.” No need to translate that to 87.

There’s much more for marketers and communicators to learn about making numbers easy to understand in the book Making Numbers Count. I’m adding this book to my reference shelf!
