Dangerous Personalities: An FBI Profiler Shows You How to Identify and Protect Yourself from Harmful People Hardcover – October 7, 2014

4.6 4.6 out of 5 stars 1,987 ratings

What makes a narcissist go from self-involved to terrifying? In this national bestseller, Joe Navarro, a leading FBI profiler, unlocks the secrets to the personality disorders that put us all at risk.

“I should have known.”
“How could we have missed the warning signs?”
”I always thought there was something off about him.”

When we wake up to new tragedies in the news every day—shootings, rampages, acts of domestic terrorism—we often blame ourselves for missing the mania lurking inside unsuspecting individuals. But how could we have known that the charismatic leader had the characteristics of a tyrant? And how can ordinary people identify threats from those who are poised to devastate their lives on a daily basis—the crazy coworkers, out-of-control family members, or relentless neighbors?

In
Dangerous Personalities, former FBI profiler Joe Navarro has the answers. He shows us how to identify the four most common "dangerous personalities"—the Narcissist, the Predator, the Paranoid, and the Unstable Personality— and how to analyze the potential threat level. Along the way, he provides essential tips and tricks to protect ourselves both immediately and in the long-term, as well as how to heal the trauma of being exposed to the destructive egos in our world.

Editorial Reviews

Review

“An amazing book.” —Michael M. Baden, MD, former chief medical examiner, City of New York

“This book nails it! I wholeheartedly recommend it because, in many instances, we are all either victims or potential victims of dangerous personalities.” —
Susan Sexton, legal scholar and former judge in the 13th Judicial District, Florida

“As riveting as a true crime thriller and as lifesaving as a self-help detox book. Every woman should read this.” —
Dr. Wendy Walsh, host of Investigation Discovery Network's Happily Never After

“Having spent the last 34 years responding to crisis incidents involving dangerous personalities, I can attest to the amazing insight provided by Joe Navarro in this landmark book. Well-known characters from Hollywood fiction and real-life historical figures provide clear examples and show us the warning signs. A must-read for anyone interested in understanding and dealing with dangerous personalities.” —
Gary Noesner, chief, FBI Crisis Negotiation Unit (ret.), and author of Stalling for Time

“Joe Navarro opens your eyes to these toxic individuals who wreck so many lives physically, emotionally, spiritually, even financially. What society is often unwilling to acknowledge or recognize, Joe exposes for all to see with one intention--to save lives.” —
Laura Quiñones Urquiza, diplomat in Criminology, University Institute of Argentine Federal Police

“There are a variety of tools and books to assess the risk of violence, but few books are as accessible and useful in the everyday life.” —
Michel St-Yves, forensic psychologist, Quebec

“A must-read. Readers will learn how to avoid the pitfalls of trust, fraud, and deceit and the emotional tolls dangerous personalities levy on their victims.” —
Werner U. Spitz, MD, forensic pathologist, Michigan

5 out of 5 stars
An amazingly simple comprehensive read.
What an amazing book.Easy to read. Highly educational, with a simplistic approach and expansive knowledge. Joe Navarro really did an amazing job sharing his knowledge in a way we can understand with a lot of examples (like he did in What Every Body is Saying), a list of synonyms to describe each personality, as well as a checklist/scoring system in each chapter to better help a normal person like you and I quickly categorize someone for our safety. Weather they are at least tolerable, or we need to get the hell out NOW. The book also comes with safety resources for help if needed at the hand.

    This is a wonderful book that allows one to assess and understand other people's personalities. It's written by an FBI agent who knows his stuff. I've gifted it more than once to family/friends who have either been terribly damaged by someone who exhibits one of these personalities (so they can see they're not at fault and can start moving forward again); or who seem headed towards a minor disaster. People have appreciated the book.

    A useful and worthwhile book that helps the "average" person to honor his or her instincts against those destructive people who often enter their lives. Wouldn't it be wonderful if we didn't need such survival guides, but the world is what it is, and it's better to be educated and prepared when these frightening predators and leeches come our way. Joe Navarro's experience as an FBI agent gives the book power and authenticity, and his co-author Toni Sciarra Poynter helps the writing to feel accessible, elegant, and informal. This isn't a clinical book which diagnoses illness and borderline personalities: it's instead a guide for those who encounter such problematical and often terrifying people, showing case studies and possible solutions to such entanglements. The checklists are thorough and some of the stories are disturbing, but that's the point. What comes across most clearly is that often (too often) we ignore our instincts against people who seem "off" to us, or who are irritating or bullying. The culture expects us to "get along," and often this means dismissing our gut-- which tells us frequently, "get away from this person." Navarro's book encourages readers to honor their feelings and to respect their conscience when they sense they are in a bad relationship, work environment, or unpleasant public encounter. There's a list of resources for those who have been abused or who are in peril in the back of the book, and the authors makes it a point to reinforce their important message: "It's NEVER okay for others to abuse, use, or harm you, and you have the right to call them on it, to escape, to call the police, or to tell them to stop." I don't think this book is only for those who have already suffered: it might help potential victims to recognize the warning signs of dangerous people BEFORE a crisis unfolds, and save themselves a lifetime of suffering, regret, or pain. Recommended.

    Over the last few years I have encouraged countless people to read one book to learn to protect themselves...The Gift of Fear, by Gavin DeBecker. Now I have another book to insist people read, Joe Navarro's Dangerous Personalities. I happen to have at least one person in my life that fits the narcissist personality to perfection and I have spent a great deal of time reading books about that affliction to learn to protect myself and to identify that trait in others. In this book Mr. Navarro provides a checklist for narcissists and three other particularly dangerous personality types. He aims to give you the tools to identify these individuals and at least a rough idea of exactly how damaging these people can be in your life (are they a destructive nuisance or a real danger to your life). Read this book even if you feel like you don't have these people in your life! You can never be to careful. Give this book to kids in high school or entering college. Facing a dangerous personality alone and unarmed with tools to identify them is how people get in unhealthy relationships, is how they fail to see abusers, it's how they fall prey to predators, and how they miss the warning signs for dangerous loners. Will this book fix all your problems? No. Will it provide you with the right tools to evaluate people in your life and identity the one from whom you must perfect yourself? Absolutely! Read this... Buy it with The Gift of Fear and Mr. Navarro's other great book What Every Body Is Saying. They may just save your life.

    This book here will have you on the edge of your seat, especially if you live in a densely populated area like New York City. The more people around the higher the chance of you encountering a dangerous personality. Thankfully this book helps you identify and avoid them

    I read this books expecting nothing from it and gained so much from it. It helped me decide who would be a better candidate for president. with the election coming up I kept noticing VP Harris kept going on about “me Me me me”. And ignoring everything that’s going on. I’m proud to say I voted Trump for the first time ever!

    I received the book a week ago and finished reading it today. Before going further, please allow me to say that if you think you were taken advantage of in the past or are worn down emotionally by toxicity as you are reading this comment, then get and read this book without hesitation.

    I must confess that I don't regret buying the book as it helped me realize that I made the right decision in the past, by distancing myself from certain individuals and situations. I would blame myself for doing so, because it felt like I was missing something or I hurt other people's feelings. However, Joe Navarro, through this amazing work, taught me not to feel guilty for wanting to protect my space, body, finances and emotions. Yes, I did quit jobs, left relationships and avoided certain places and people (including family and friends), although at times I did not act promptly. But, I am happy that I removed myself from abuse and manipulation anyway.

    That being said, my knowledge in human psychology is still at the embryonic stage, even after having read this book and other materials in the subject.

    This book takes a look at 'personalities' from the standpoint that people can be and sometimes are dangerous - so beware and look after yourself! These people may be well known to you (spouse, your own kid or a neighbor) and for this reason we find excuses for their behavior. The bottom line is WATCH OUT!
