Jordan B. Peterson's books have sold millions of copies worldwide. The expansive tours that accompanied their publication have brought him in front of a quarter of a million people in some five hundred venues, and his online lectures and podcasts have been seen and heard by a billion viewers and listeners. Before becoming one of today's most influential public intellectuals, he worked for decades as a professor at Harvard and the University of Toronto, and as a practicing clinical psychologist. He has published more than a hundred scientific papers on a range of topics including personality, criminal behavior, political and religious belief, and the neuroscience of perception, motivation and emotion. He has developed a range of extraordinarily popular self-development, educational and communication tools, including selfauthoring.com and understandmyself.com, Peterson Academy, and Essay.app. He lives in Toronto, Canada, with his wife, Tammy. They have two children and four grandchildren.
