Steve Jobs, Harvey Weinstein, Lance Armstrong, Donald Trump. Each one reached the pinnacle of American success. Is it because they were ambitious visionaries and talented entrepreneurs? Most Americans would say yes to both. But what else do they have in common?

They’re known for being mean.

Drawing on author Mark Lipton’s extensive experience as adviser to major corporations, start-ups, government agencies, and not-for-profits, Mean Men synthesizes decades of psychological research to expose what really drives this subset of America’s leaders. As surprising as it is alarming, the book reveals dark truths about a psychological disorder that rules many of our boardrooms, and challenges the status quo with a more effective humanistic approach to leadership.

Mean Men has:

  • Won the 2018 Best Business Commentary Book Award. (Axiom Business Book Awards).

  • Won the 2017 Indie Book Award for Social Science. (Forward Book Awards)

  • Become selected as a 2018 Finalist for the George R. Terry Book Award by the Academy of Management.
