I am a psychologist and professor of Organizational Behavior. I consult with organizations and teach on dark personalities in the workplace, employee selection, corporate fraud, and leadership. I have published empirical research on leadership, employee selection, narcissism and psychopathy in the workplace, and employee well-being.

For the past ten years, I have studied individuals in the workplace who present dark personalities such as narcissism and psychopathy. I have published research papers on the subject, given many presentations, and consulted with different organizations (private sector, government agencies, and law enforcement).

Considering the negative impact that these individuals have on workplaces, I have decided that it was time for me to put my knowledge into a book that would help students and professionals. The book will help readers understand who these individuals are, how they manage to enter organizations, obtain management positions, and the damages they create on the inside.

Like all of my classes, each chapter of this book is divided into two sections. The first section presents theory based on clinical, social, criminal,industrial-organizational psychology, and business research. I believe that theory allows us to understand the WHAT and WHY; for instance, what constitutes a dark personality, and why individuals with dark personalities act and react the way they do. The second section of each chapter is a practice section that allows to answers the HOW. The practice section includes practical solutions to help readers understand how to prevent these individuals from entering organizations and how to deal with them once they are on the inside. Practical exercises conclude each chapter, and free additional material is available for students, academics, and organizations on my website (www.cynthiamathieu.com). On my website, you will also find a blog on dark personalities in the workplace and videos from my Youtube channel.
