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.

Using concrete language significantly increased customer satisfaction.

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.

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.
