Early in my career, I learned an important lesson about listening.
I worked in an organization filled with confident, talkative people who thought out loud and easily filled the space with their words. Conversations were lively, ideas flowed quickly, and the loudest voices often dominated discussions.
Yet one person stood out to me, not because she spoke more than everyone else, but because she didn’t.

She rarely spoke during meetings, and at times, people wondered whether she was even engaged in the conversation.
But I quickly learned to pay attention to her and to seek out her perspective. When she did speak, her insights were thoughtful and clear. She had an incredible ability to clarify multiple perspectives and help the group see the situation more clearly than anyone else in the room. And she delivered those insights with quiet authority.
I admired her ability.
That experience reflects the core message of Susan Cain’s book, Quiet. We often overlook the quiet people in the room. Western society tends to favour the extrovert ideal, and this bias doesn’t consistently produce better results. In fact, it often leads to unintended consequences.
Understanding this bias is especially important for leaders navigating organizational change. Especially the way organizations often think about “resistance” to change, a bias that makes change more difficult and leads to missed opportunities and poor decision-making.
Extrovert Versus Introvert
There isn’t one single definition of an extrovert or an introvert. It also isn’t as simple as being entirely one or the other.
However, there is general agreement that what differentiates extroverts from introverts is where they draw their energy from and how they expend it.
Extroverted individuals tend to gain energy from the outside world. They often prefer action over contemplation, think out loud, solve problems through discussion, and make decisions more quickly. Being around other people can recharge their energy.
Introverts, on the other hand, draw their energy from within. They may have strong social skills, but they recharge through reflection and time alone. They tend to talk less, think more deeply before responding, solve problems internally, and rarely make quick decisions.
These differences influence how people work, how they interact with others, and the type and level of stimulation they need.
Importantly, one is not better than the other. That is the central message of Susan Cain’s book. She argues that society makes a serious mistake by unquestioningly embracing the extrovert ideal.
As she explains, “We are told that to be great is to be bold, to be happy is to be sociable. We see ourselves as a nation of extroverts.” Western culture has developed a strong bias toward the extrovert ideal.
Yet many of the most important ideas in art, technology and science have come from individuals who were deeply connected to their inner worlds and the insights found there.
The Extrovert Ideal and Its Impact on Change
Susan Cain traces the rise of the extrovert ideal in Western society in part to the influence of Dale Carnegie. It was his journey from farm boy to salesman to public-speaking icon that helped popularize the idea that success required charisma and social boldness.
Over time, American society shifted from a culture of character to a culture of personality. By default, much of Western society followed the same path.
Gregariousness became something to aspire to. Educators and parents began encouraging outgoing behaviour. Solitary play was discouraged. Being quiet or shy became something people felt they needed to overcome.
Susan even describes how universities such as Harvard and Yale in the 1950s shaped their admissions practices to favour the gregarious while avoiding students who were seen as intellectually overstimulated.
According to Susan, this shift has not served society well. The goal isn’t to abandon extroversion, but to recognize the equal value of introversion.
Beware of the Bias
Research shows that the bias toward extroversion often leads to faulty assumptions. For example, many people believe that talkative individuals are more intelligent. Yet there is no empirical evidence to support this perception. Measures such as grade point averages, intelligence tests, and SAT scores show no difference between extroverts and introverts.
Other research suggests that people who speak quickly are often perceived as more creative, appealing, and capable problem-solvers than those who speak more slowly. But, as Susan Cain points out, this would only matter if talking more actually produced better ideas.
Research consistently shows that it does not.
One of the most memorable stories from the book involves an exercise used with incoming Harvard Business School students called the Subarctic Survival Situation.
In the exercise, students imagine their plane has crashed in the subarctic region near the Northern Quebec–Newfoundland and Labrador border. They are given a list of 15 salvaged items. They must first rank them individually, then rank them as a group according to their importance for survival.
The team fails the exercise if any individual member’s ranking is more accurate than the group’s.
That is exactly what happened when assertiveness was valued more than thoughtful input.
In one group, a student with extensive experience in northern backwoods offered important insights. However, he was one of the quiet members of the group. More vocal members of the group spoke with great confidence and dismissed his ideas.
Ironically, the ideas rejected were the ones that would have saved their lives if the scenario had been real.
How the Extroverted Bias Can Affect Your Organizational Change Efforts
A similar dynamic can occur during organizational change initiatives.
Leaders may move too quickly when implementing change, without fully considering the ripple effects and broader consequences. People who raise thoughtful concerns may be labelled as resistant to change.
At the same time, organizations may hold a strong belief that employees resist change. This bias can cause leaders to overlook the quieter signals that people may actually be ready for change.
When organizations fail to listen to quieter voices, they miss valuable insights and contributions from a significant portion of their workforce.
As Susan Cain and the research she cites suggest, the healthiest and most effective teams include a mix of extroverts and introverts.
Creating an Inclusive Environment
If the strength of any organization lies in its people, and society tends to favour extroversion, how can leaders create space for quieter voices to be heard?
Susan Cain offers several practical suggestions.
First, create an inclusive environment that recognizes different ways people recharge, think, and create.
For example, one organization we worked with wanted to increase collaboration and interaction. They redesigned their physical space to include more areas where employees from different departments could gather and socialize.
At the same time, they created accessible and attractive quiet spaces where employees could reflect and recharge. Individual offices were also retained so that people could choose environments that supported their best work.
Second, give people time to reflect and process, even when working in groups.
In a culture that values bold action and quick responses, reflection is often undervalued. Early in my career, I learned that when I built time for individual reflection before asking for group input, quieter members participated more fully and no single person dominated the discussion.
Third, recognize that both introverts and extroverts bring valuable strengths.
During times of change, organizations benefit from individuals who carefully analyze problems, explore possible scenarios, and quietly develop new ideas. At the same time, organizations also benefit from individuals who bring energy, enthusiasm, and a willingness to take action.
Both perspectives are important.
An Important Lesson
Reading Quiet reinforced an important lesson: silence does not mean agreement or disengagement.
Leaders must create environments where every individual is respected and enabled to contribute. If organizations default to listening only to the loudest voices in the room, they risk missing critical insights.
Making space for different interaction styles requires time, patience, and thoughtful leadership. But when organizations do this well, they unlock the full potential of their people.
