How Metaphors Help—And Hurt—Science

Metaphors can help us understand complicated scientific concepts. But they can also have a downside.

Here at Science Friday, we’re big fans of metaphors. They can make complicated scientific concepts easier to understand, for both non-experts and scientists themselves. For example, “the big bang” helps us visualize the beginning of the universe. Or we can understand DNA’s role better as a “building block of life.”

But some of these scientific metaphors also have a downside, and can even set research back.

Sam Harnett and Chris Hoff are the hosts of the podcast series “The World According to Sound,” and they sat down with Science Friday’s Director of News and Audio, John Dankosky, to talk about their new project, “An Inexact Science.” They discuss a special two-hour episode that explores how language and metaphor have shaped science, for better or worse.


Universe of Art is hosted and produced by D Peterschmidt, who also wrote the music and produced the original segment. Our show art is illustrated by Abelle Hayford. And support for Science Friday’s science and arts coverage comes from the Alfred P. Sloan Foundation.
