The Science of Infographics — Key Insights from Randy Krum’s “Cool Infographics”
Infographics: The Science Behind Their Impact
Infographics aren’t just visually appealing tools — they are an efficient means of communication, especially in an age where information overload is a real challenge. Randy Krum’s Cool Infographics: Effective Communication with Data Visualization and Design delves deeply into why these visual representations are so effective and how they are backed by cognitive science.
In this article, I’ll share ten key takeaways from the first 29 pages of Cool Infographics to explain why infographics work so well and why they should be a go-to tool for educators, businesses, and designers alike.
1. Human Brains Are Wired for Visuals
Krum opens with a reminder of why people love infographics — humans are biologically wired to understand and retain visual information more effectively than text. The brain processes visual content 60,000 times faster than text. As Krum notes, “vision is by far our most dominant sense, taking up half of our brain’s resources”(Cool Infographics). Infographics capitalize on this strength, making complex information more digestible.

2. Infographics Make Data Accessible
Data visualizations — charts, graphs, and other tools — help distill massive datasets into comprehensible stories. By converting raw data into visuals, infographics enable readers to detect patterns, spot trends, and make decisions more rapidly than by analyzing spreadsheets. This is an essential benefit in educational settings, where simplifying complex information enhances student engagement and learning.
3. Pattern Recognition Powers Understanding
Humans are innate pattern recognizers. Our brains instinctively look for patterns, shapes, and trends, which is why infographics that visualize relationships within data resonate deeply. This principle makes it easier for educators to teach intricate subjects such as scientific models or historical trends.
4. The Picture Superiority Effect
Krum introduces the Picture Superiority Effect, which explains how combining relevant images with text boosts memory retention by 650% (Cool Infographics). A simple chart or illustration paired with an explanation significantly improves the likelihood of the audience remembering the message. For educators, this is crucial when aiming to leave a lasting impression on students.

5. Storytelling Enhances Engagement
Infographics, Krum argues, are at their best when they tell a compelling story. A well-designed infographic follows a narrative structure — starting with an introduction, moving to the key message or Ah-Ha moment, and closing with a conclusion or call-to-action(cool-infographics-effec…)(cool-infographics-effec…). This is not just important for marketers or advertisers but is equally effective for educators who want to make lessons more engaging.
6. The Language of Context
Context is everything when interpreting data. Infographics excel at providing this context by visually comparing multiple data points, allowing the audience to grasp meaning more quickly. For example, a standalone number might mean little until juxtaposed with related data, providing clarity.
7. Simplicity Matters
The key to a good infographic, according to Krum, is clarity and simplicity. Too many details overwhelm the viewer, making it harder to grasp the main message. Infographics should focus on delivering one core idea effectively rather than cramming too much information.
8. Minimizing Bias in Data Visualizations
Every designer must acknowledge the inherent bias in their work. Choices about which data to include, what visual forms to use, and even color schemes can introduce bias. Infographics should strive for transparency and balance, presenting data in a way that educates rather than manipulates.
9. Educators Benefit from Cognitive Insights
Krum’s exploration of the science of infographics is especially relevant for educators, who often seek innovative ways to break down complex subjects. Infographics aid in memory retention, contextual understanding, and cognitive engagement — all critical factors for improving learning outcomes.
10. Conclusion and Call-to-Action
Infographics should always conclude with a clear wrap-up or call-to-action, guiding viewers on what to do next. Whether it’s encouraging students to apply their knowledge, or prompting them to explore further, closing with actionable steps ensures that the information presented isn’t just passively consumed.
Wrapping It Up
Krum’s Cool Infographics provides designers and educators alike with a solid foundation for understanding the powerful science behind visual communication. Whether you’re trying to explain complex concepts in the classroom or present data in a business meeting, the principles outlined in this book are invaluable.
