Something You Should Know

When Maps Go Wrong & The Science of Everyday Courage

November 6, 2025

Key Takeaways Copied to clipboard!

  • Using overly complex or big words tends to make a speaker sound less intelligent, as people value fluency and ease of understanding more than vocabulary size. 
  • Maps, even modern ones, inherently involve distortion to make complex information readable, and historical maps were often decorative rather than purely navigational tools. 
  • Courage is not the absence of fear, but rather the ability to take action in the face of fear, a skill that can be learned through deliberate strategies to manage the uncertainty that fear originates from.

  • Key Takeaway: Fluency, or the ease with which something is understood, is valued more than a fancy vocabulary, leading listeners to judge the author as smarter and more credible.
  • Summary: Research indicates that attempting to sound intelligent by using big words often backfires, making the speaker sound less intelligent. People prioritize the ability to read and understand content easily. Higher fluency correlates with perceptions of greater intelligence, confidence, and credibility in the author.
History and Inaccuracies of Maps

  • Key Takeaway: Early maps were primarily decorative works of art for monarchs, and many modern maps contain deliberate errors or distortions, such as copyright traps or geographical omissions like New Zealand.
  • Summary: The first maps were not for navigation but served decorative purposes; accuracy only recently became the main priority. Maps must distort reality to be useful, exemplified by schematic transit maps that discard scale for clarity. Copyright traps, like the invented town of Aglo, are deliberately placed errors to catch unauthorized copying.
Geopolitical Map Controversies

  • Key Takeaway: The widely used Mercator projection distorts the scale of landmasses, making areas near the poles appear disproportionately large, leading the African Union to advocate for its replacement.
  • Summary: The Mercator projection inflates the size of countries near the poles, such as making Greenland appear the size of Africa, while shrinking equatorial regions. This distortion is viewed by some as a colonialist way of representing the world. Alternative projections, like the Makato projection, better represent the true scale of landmasses.
Courage Science and Self-Talk

  • Key Takeaway: Courage is defined as taking action in the face of fear, not the absence of it, and ordinary people can learn strategies to overcome the paralyzing self-talk associated with uncertainty.
  • Summary: Courageous individuals are not fearless; they experience fear but choose to act despite it, often by reframing their internal narrative. Fear originates from uncertainty, which leads to loss avoidance, where the pain of a negative outcome outweighs the pleasure of a positive one. Strategies exist to tame fear and develop generalized ‘can-do’ efficacy, allowing people to act boldly.

  • Key Takeaway: The Japanese company YKK produces an estimated half of all zippers globally, maintaining an unmatched reputation for consistency and reliability in its core product.
  • Summary: YKK, founded in 1934, dominates the global zipper market, producing billions annually. Their zippers are trusted by manufacturers because they rarely jam, split, or corrode. The company’s success is a master class in precision, persistence, and quality control.
