The Language of Infographics: Toward Understanding Conceptual Metaphor Use in Scientific Storytelling
This paper applies Conceptual Metaphor Theory to analyze scientific infographics across four domains, identifying prevalent ontological and orientational metaphor patterns to establish a formal taxonomy and grammar for visual storytelling, supported by a new visual exploratory tool.

Imagine you are trying to explain a complex, invisible world—like the inside of a human cell or the vastness of space—to a friend who has never studied science. You can't just hand them a textbook; it's too dry and confusing. Instead, you say, "Think of the cell's nucleus like a library," or "Imagine global warming as a blanket that's getting too thick."
You just used metaphors. You took something familiar (a library, a blanket) and used it to explain something unfamiliar (a cell, climate change).
This paper is essentially a detective story about how scientists and designers use these "mental shortcuts" in infographics (those pretty, data-filled pictures you see in magazines and online). The authors wanted to stop guessing why certain pictures work and start understanding the "grammar" of visual metaphors.
Here is the breakdown of their findings, translated into everyday language:
1. The Four Types of Visual "Tricks"
The authors realized that not all metaphors are created equal. They sorted them into four buckets, like different tools in a toolbox:
- The "Look-Alike" (Imagistic): This is the simplest one. It's like saying, "This cell membrane looks like a patch of fabric with stitches." It's purely about appearance. It helps you see what it looks like, but it doesn't explain how it works.
- The "Direction" Trick (Orientational): This uses space to explain time or feelings. Think of a timeline where the past is on the left and the future is on the right. Or, imagine a graph where "up" means "good" and "down" means "bad." It's like using a compass to navigate a concept.
- The "Personification" Trick (Ontological): This is where we turn abstract ideas into things or people. For example, treating a virus like a "bad guy" or a ribosome (a tiny cell machine) like a "coffee shop worker." It gives a face or a body to something that doesn't have one, making it easier to talk about.
- The "Whole Story" Trick (Structural): This is the heavyweight champion. It maps an entire complex system onto a familiar one. The classic example: "The cell is a city." You don't just say the nucleus is a library; you say the cell is a city, the DNA is the city plan, and the power plants are the mitochondria. It connects a whole network of ideas at once.
2. What They Found (The "Aha!" Moments)
The team looked at 55 infographics from four big worlds: Medicine, Climate, Space, and History (Anthropology). Here is what they discovered:
- The "City" and "Compass" are King: Surprisingly, the most complex "Whole Story" tricks (Structural) were rare. Instead, designers loved the "Direction" (Orientational) and "Personification" (Ontological) tricks.
- Why? Because complex stories are hard to digest quickly. It's easier to say "Up is good" or "This virus is a thief" than to explain an entire ecosystem. It keeps the brain from getting tired.
- Climate Change is Emotional: In climate infographics, designers used these metaphors to make us feel something. They used red colors (like a fire) to mean "danger" and "urgency." They wanted you to feel the heat so you'd want to act.
- Space is Weird: Space infographics were unique. Because space is so strange, they often broke the rules. Instead of time going left-to-right, they sometimes used spirals or went right-to-left to show that we are looking back in time at stars that died millions of years ago.
- History is Boring (Metaphor-wise): History maps used the fewest metaphors. They just used arrows and dots. Why? Because maps need to be accurate. If you turn a battle into a "war of giants," you might lose the real facts. Sometimes, a simple arrow is better than a fancy story.
3. The "Text" Safety Net
The authors noticed that pictures alone can be confusing. If you see a picture of a "library" inside a cell, you might not know why it's there.
- The Solution: Text acts as the glue. A title or a caption explains the metaphor. "The Nucleus: The Library of the Cell." The text tells your brain, "Hey, don't just look at the picture; use this comparison to understand the science."
4. The Big Takeaway
Right now, making science infographics is a bit like cooking without a recipe. Designers rely on intuition. They might throw in a metaphor because it "looks cool," not because it actually helps people understand.
This paper is like writing the first cookbook for visual science.
- It gives designers a vocabulary to talk about why a picture works.
- It helps them choose the right "tool" (Imagistic, Orientational, Ontological, or Structural) for the job.
- It warns them not to overcomplicate things. Sometimes, a simple arrow is better than a complex story.
In a nutshell:
Science is full of invisible, confusing things. Infographics are the bridge. This paper teaches us how to build that bridge stronger by understanding that metaphors are the bricks, and knowing which brick to use (a person, a direction, a shape, or a whole story) makes the bridge safe for everyone to cross.
