"Whether it's banks versus robbers, Hollywood versus
downloaders, or even the Iranian secret police against democracy
activists, security is often a dynamic struggle between a majority
who want to impose their will, and a minority who want to push the
boundaries. Liars and Outliers will change how you think
about conflict, our security, and even who we are."
—ROSS ANDERSON, Professor of Security Engineering at Cambridge University and author of Security Engineering
"Readers of Bruce Schneier's Liars and Outliers will
better understand technology and its consequences and become more
—PABLO G. MOLINA, Professor of Technology Management, Georgetown University
"Liars & Outliers is not just a book about
security—it is the book about it. Schneier shows that the
power of humour can be harnessed to explore even a serious subject

"This fascinating book gives an insightful and convincing
framework for understanding security and trust."

Liars and Outliers provides great insight into resolving
society's various dilemmas."
—JERRY KANG, Professor of Law, UCLA
"By keeping the social dimension of trust and security in the
center of his analysis, Schneier breaks new ground with an approach

the way you see the world."
—DAVID LIVINGSTONE SMITH, author of Less Than Human: Why We Demean, Enslave, and Exterminate Others
"Schneier tackles trust head on, bringing all his intellect and
a huge amount of research to bear. The best thing about this book,
though, is that it's great fun to read."
—ANDREW MCAFEE, Principal Research Scientist, MIT Center for Digital Business and co-author of Race Against the Machine
"Bruce Schneier is our leading expert in security. But his book
is about much more than reducing risk. It is a fascinating,
thought-provoking treatise about humanity and society and how we
interact in the game called life."
—JEFF JARVIS, author of Public Parts: How Sharing in the Digital Age Improves the Way We Work and Live
"Both accessible and thought provoking, Liars and
Outliers invites readers to move beyond fears and anxieties
about security in modern life to understand the role of everyday
people in creating a healthy society. This is a must-read!"
—DANAH BOYD, Research Assistant Professor in Media, Culture, and Communication at New York University
"Trust is the sine qua non of the networked age and trust is
predicated on security. Bruce Schneier’s expansive and
readable work is rich with insights that can help us make our

Society runs on trust. We have no choice but to trust that the random people, institutions, and systems we interact with will cooperate and be trustworthy. We don’t need to trust completely or blindly, but we need to be reasonably sure our trust is well-founded. But within this web of trust, the untrustworthy can thrive. Much of the work of society centers around this tension between cooperators and defectors in society. But not all defectors are bad – such as those that rallied against slavery. Defectors change as society changes; defection can be in the eye of the beholder.
In his new book, LIARS & OUTLIERS: Enabling The Trust That Society Needs To Thrive, world-renowned thought leader Bruce Schneier identifies how security can protect us from defectors; and what enables us to trust strangers at the local, national, and global scale. “Trust and cooperation are the first problems we had to solve before we could become a social species – but in the 21st century, they have become the most important problems we need to solve again,” says Schneier, author of eleven books, including the bestsellers Secrets & Lies and Beyond Fear.
LIARS & OUTLIERS introduces ideas from across the social and biological sciences to explain how society induces trust. It demonstrates how trust works and fails in social settings, communities, organizations, and countries. A leading expert on technology and security, Schneier explains why we need to understand our evolved security systems and their unique role in facilitating and stabilizing human society. Most importantly, he explains how “cooperation” is defined by social convention, and that there are two kinds of “uncooperative” people: those who are selfish, and those who are differently moral than the rest of society.
In the book he also explains:
• The history and evolution of people and trust – and how to think of this relationship between society as a whole and its defectors as a parasitic relationship: As societies became more social, they needed to learn how to get along with each other: both cooperating and ensuring everyone else cooperated, too. That’s never been truer than it is today; yet we’re still getting it wrong.
• The problem isn’t trusting people; the problem is with the dilemma: People are more complicated than societal dilemmas, i.e., choices between group interests and competing individual interests. Our competing interests are more nuanced and varied, and they’re subjective and situational. It’s more important we understand which societal pressures reduce the scope of defection, and how each should be scaled to keep society’s parasites down to a tolerable level.
• The need to not only trust strangers, but trust systems and institutions: It’s important to trust that defectors won’t take advantage of a group, but it’s also important to trust that institutions and systems won’t take advantage as well. Although sometimes laws aren’t enough, institutional rules allow reputation to scale, by giving people a system to trust so they don’t necessarily have to trust individuals. Systems are the last layers of defense – and the most scalable – against defection.
• Real-world applications for understanding and scaling societal pressures: There are a variety of competing interests that can cause someone to defect and not act in the group norm. Today, this largely includes how certain societal dilemmas affect corporations; how major corporations can play one societal dilemma off another; and how increasing the power and scale of corporations can prompt them to do whatever illegal activity is under consideration.
Schneier’s message isn’t that defectors will ruin everything for everyone, but that we need to manage societal pressures to ensure they don’t. Our global society has grown so large and complex that our traditional trust mechanisms no longer work. Today’s problems require new thinking, and as World Economic Forum chairman Klaus Schwab so eloquently says, “Without trust nothing can be achieved. LIARS & OUTLIERS is a brilliant analysis of the role of trust in society and business.”
