Mission statements, synergies, strategies, visions—they are often ambiguous to the point of being meaningless. Naturally sticky ideas are full of concrete images —ice-filled bathtubs, apples with razors—because our brains are wired to remember concrete data. In proverbs, abstract truths are often encoded in concrete language: “A bird in hand is worth two in the bush.

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.

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.

Rather than focusing on one niche, abstract language makes the market seem widespread. And given that larger growth potential, a company seems like a much more promising investment.

Consequently, whether it’s better to use concrete or abstract language depends on the outcome we’re trying to achieve. Want to help people understand a complex idea, feel heard, or remember what was said? Using concrete language is going to be more effective.

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.
