Using concreteness as a foundation for abstraction is not just good for mathematical instruction; it is a basic principle of understanding. Novices crave concreteness. Have you ever read an academic paper or a technical article or even a memo and found yourself so flummoxed by the fancy abstract language that you were crying out for an example?

Or maybe you’ve experienced the frustration of cooking from a recipe that was too abstract: “Cook until the mixture reaches a hearty consistency.” Huh? Just tell me how many minutes to stir! Show me a picture of what it looks like! After we’ve cooked the dish a few times, then the phrase “hearty consistency” might start to make sense. We build a sensory image of what that phrase represents. But the first time it’s as meaningless as 3 + 2 + 1 would be to a three-year-old.

This is how concreteness helps us understand—it helps us construct higher, more abstract insights on the building blocks of our existing knowledge and perceptions. Abstraction demands some concrete foundation. Trying to teach an abstract principle without concrete foundations is like trying to start a house by building a roof in the air.

Even the most abstract business strategy must eventually show up in the tangible actions of human beings. It’s easier to understand those tangible actions than to understand an abstract strategy statement— just as it’s easier to understand a fox dissing some grapes than an abstract commentary about the human psyche.

Abstraction makes it harder to understand an idea and to remember it. It also makes it harder to coordinate our activities with others, who may interpret the abstraction in very different ways. Concreteness helps us avoid these problems. This is perhaps the most important lesson that Aesop can teach us.

Concrete language helps people, especially novices, understand new concepts. Abstraction is the luxury of the expert. If you’ve got to teach an idea to a room full of people, and you aren’t certain what they know, concreteness is the only safe language.

We need to make the abstract concrete. Whether talking to colleagues or clients, students or sales reps, patients or program managers, we need to take abstract ideas and make them real by using concrete language. Helping people understand, and act on, what we’re saying.

More generally, when trying to make language either more concrete or more abstract, one helpful approach is to focus on either the how or the why.

Want to be more concrete? Focus on the how. How does a product meet consumer needs? How does a proposed new initiative address an important problem? Thinking about how something is or will be done encourages concreteness. It focuses on the feasibility and helps generate concrete descriptions.

Want to be more abstract? Focus on the why. Why does a product meet consumer needs? Why does a proposed new initiative address an important problem? Thinking about why something is good or right encourages abstractness. It focuses on its desirability and helps generate abstract descriptions.

Consequently, we need to harness the power of linguistic concreteness.

  • Make people feel heard. Want to show someone you’re listening? Be concrete. Give specific details that show we paid attention and understood.
  • Be concrete. Don’t just pick things that sound good, use words that listeners can see in their minds. It’s a lot easier to imagine a red sportscar than ideation.
  • Focus on the How. Thinking about the nuts and bolts of how something will happen, and focusing on specific actions, makes things concrete.

But while concrete language is often useful, if our goal is to come off as powerful, or make something seem like it has growth potential, using abstract language is better. In those cases:

  • Focus on the why. Thinking about the reasoning behind something helps things stay high level and communicate that big picture.
