Let s start with a short personality test. For each of the following

dimensions, indicate the extent to which each of the following words describes

you, with a 5 indicating very much so and a 1 indicating not at all :

assertive, talkative, bold, not reserved, and energetic. Now sum up your

scores. What s the total?

If you scored under 10 points, you are likely to have an introverted

personality rather than an extroverted one. If that is the case, you are

certainly not alone. Studies find that introverts make up one-third to one-half

of the population. Yet most workplaces are set up exclusively with extroverts

in mind, a fact that becomes clear when you look at traits associated with the

two personality types.

Extroverts gravitate toward groups and constant action, and they tend to think

out loud. They are energized and recharged by external stimuli, such as

personal interactions, social gatherings, and shared ideas. Being around other

people gives them energy. In contrast, introverts typically dislike noise,

interruptions, and big group settings. They instead tend to prefer quiet

solitude, time to think before speaking (or acting), and building relationships

and trust one-on-one. Introverts recharge with reflection, deep dives into

their inner landscape to research ideas, and focus deeply on work.

What do these tendencies mean for the ability of extroverts and introverts to

succeed in team settings, where they must interact and sometimes lead others?

My research suggests that the answer depends on the types of team members being

led.

Team leaders who are extroverted can be highly effective leaders when the

members of their team are dutiful followers looking for guidance from above.

Extroverts bring the vision, assertiveness, energy, and networks necessary to

give them direction.

By contrast, when team members are proactive and take the initiative to

introduce changes, champion new visions, and promote better strategies it is

introverted leaders who have the advantage. Extroverted leaders are more likely

to feel threatened, I ve found. When employees champion new visions,

strategies, and work processes, they often steal the spotlight, challenging

leaders dominance, authority, and status. As a result, extroverted leaders

tend to be less receptive: They shoot down suggestions and discourage employees

from contributing. By comparison, an introverted leader might be comfortable

listening and carefully considering suggestions from below. This finding is

consistent with a wealth of research on what is known as dominance

complementarity: the tendency of groups to be more cohesive and effective when

they have a balance of dominant and submissive members.

The intuition here is that extroverted leadership may drive higher performance

when employees are passive but lower performance when employees are proactive.

To test this idea, my colleagues Adam Grant of Wharton, Dave Hofmann of the

University of North Carolina at Chapel Hill, and I studied a U.S.

pizza-delivery chain. Since the stores in the chain were highly similar, they

offered a natural opportunity to track whether their success varied as a

function of extroverted leadership and employee proactivity.

With the goal of isolating the influence of extroverted leadership, we compared

the profitability of 57 different stores. We assessed each store leader s

levels of extraversion how assertive, talkative, bold, and energetic he or

she was. In addition, an average of six to seven employees per store completed

surveys about how proactive their store was as a group: to what extent did they

voice suggestions for improvement, attempt to influence the store s strategy,

and create better work processes?

Then, for the following seven weeks, we tracked each store s profits. We

statistically adjusted for factors beyond the leader s control, such as the

average price of pizza orders and the total number of employee labor hours. We

found that extroverted leadership was linked to significantly higher store

profits when employees were passive but significantly lower store profits when

employees were proactive. In stores with passive employees, those led by

extroverts achieved 16% higher profits than those led by introverts. However,

in stores with proactive employees, those led by extroverts achieved 14% lower

profits. As expected, extroverted leadership was an advantage with passive

groups, but a disadvantage with proactive groups.

These results suggest that introverts can use their strengths to bring out the

best in others. Yet introverts strengths are often locked up because of the

way work is structured. Take meetings. In a culture where the typical meeting

resembles a competition for loudest and most talkative, where the workspace is

open and desks are practically touching, and where high levels of confidence,

charisma, and sociability are the gold standard, introverts often feel they

have to adjust who they are to pass. But they do so at a price, one that has

ramifications for the company as well.

How can you get the best from deep, quiet team members during meetings? A look

at practices used in some organizations points to an answer. At Amazon, every

meeting begins in total silence. Before any conversation can occur, everyone

must quietly read a six-page memo about the meeting s agenda for 20 to 30

minutes. Amazon CEO Jeff Bezos instituted this process after recognizing that

employees rarely read meeting materials sent in advance. Reading together

focuses everyone s attention on the issues at hand.

The real magic happens before the meeting ever starts, when the author is

writing one of these six-page memos, which are called narratives. The memos

must tell a story: They have a conflict to resolve and should conclude with

solutions, innovation, and happy customers a structure that provides the

meeting with direction. Writing forces memo authors to reason through what they

want to present, spend time puzzling through tough questions, and formulate

clear, if not persuasive, arguments. It s no surprise that Bezos also banned

PowerPoint presentations in meetings, thus doing away with simplistic and fuzzy

bullet-point logic.

The type of clear thinking that these structured memos require also serves the

purpose of leveling the playing field for team members who differ in their

level of introversion and extroversion. The imposition of writing as a medium

turns self-discipline and personal reflection into effective meetings and

participative decision making. After devoting time to reading, the group can

then focus on engaging in a valuable discourse: reaching shared understandings,

digging deeper into data and insights, and perhaps most importantly, having a

meaningful debate. The process gives introverted team members the time they

need to formulate their thoughts and, for some, build up the courage to share

them with the rest of the team. It also encourages the extroverted to listen,

reflect, and become more open to the perspectives of their more silent peers.

Thinking more carefully about how to structure meetings can be very helpful to

make sure they produce good outcomes. And it can also assure management can get

the best out of the introverted members, in addition to the more extroverted

ones.
