Susan Cain

On the hidden powers of introverts.

Susan Cain is the author of the bestsellers Quiet Journal; Quiet Power: The Secret Strengths of Introverts; and Quiet: The Power of Introverts in A World That Can’t Stop Talking, which has been translated into 40 languages. Her 2012 TED talk has been viewed over 30 million times and was named by Bill Gates as one of his all-time favorite talks. Cain’s work sparked a worldwide conversation and changed the way we see introverts, as well as the way introverts see themselves.

1. Susan Cain’s Key Findings and Messages

  • Introverts – those who prefer quiet, low-key environments – offer worthy contributions of creativity, talent and intellect.
  • The cultural bias against introverts hampers innovation and productivity, as well as opportunities for better leadership.
  • Society, education and business would benefit from a cultural balance between introversion and extroversion.

There’s zero correlation between being the best talker and having the best ideas.

2. Why Do They Matter?

Though a third to a half of the total population is introverted, most classrooms and offices are designed for extroverts. Meanwhile, our extroverted culture too often overlooks the extraordinary contributions introverts quietly make. In Quiet, Susan Cain gives introverts the tools to better understand themselves and take full advantage of their strengths. An introvert herself, Cain has become a self-appointed advocate for the soft-spoken and reflective, helping millions of introverts around the world find a voice.

3. To Understand Cain’s Work, Start Here

Susan Cain’s 2012 TED talk catapulted her from (quiet) obscurity to worldwide fame. In her talk, she makes a strong case for the creative potential of a quiet mind. Her lesson: Listen to introverts, even if it means listening a little bit harder.


  • Introverts – those who prefer quiet, low-key environments – offer worthy contributions of creativity, talent and intellect.
  • Modern culture tends to overlook or discount introverts, including their creative and leadership potential.
  • People should enable independent work in offices and classrooms, cultivate the practice of introspection, and ensure that introverts’ voices are heard.

The more freedom that we give introverts to be themselves, the more likely that they are to come up with their own unique solutions to…problems.

4. Evaluate the Details: Cain’s Books

Cain’s breakout bestseller, Quiet: The Power of Introverts in a World That Can’t Stop Talking, shows how American culture misunderstands and undervalues introverts, and thus fails to take full advantage of their contributions. The book also offers practical advice on how to navigate life as an introvert in an extroverted culture. Here are a few highlights:

  • Introversion and extroversion are preferences for certain levels of stimulation.
  • Introverts prefer less external stimuli – noise, interactions, new experiences, social expectations – and like to investigate a novel situation before getting involved.
  • Throughout the ages, introverts have left their mark on history. Famous 20th-century introverts include Eleanor Roosevelt, Al Gore, Warren Buffet and Mahatma Gandhi, among many others.
  • Many successful CEOs are introverts. They excel at leading creative and innovative employees because introverts are more likely to listen and implement suggestions.
  • Public schools and most workplaces do not facilitate or encourage solitary work but encourage team work instead.
  • While teamwork and collaboration are important, introverts tend to show their leadership with innovation and brilliance when given a chance to work independently.
  • Introverts need to rely on their intuition and honor their style of sharing their ideas.

Cain wrote three follow-up books. Quiet Power: The Secret Strengths of Introverts is written for young introverts (adolescence to mid-20s). It offers guidance on navigating school, family life and friendships while finding their own place in the world. Quiet Power: The Secret Strengths of Introverted Kids is written for an even younger audience. Illustrated with comic-style art, it uses stories of kids tackling the challenges of not being extroverted while making a mark in their own quiet way. Quiet Journal, meanwhile, offers a self-assessment quiz for introverts and journal writing prompts for self-exploration.
