George’s book looks at five different types of bad bosses. Zuckerberg falls into not one but three of those categories. He has become a loner who avoids forming close relationships and pushes others away. He is a rationalizer, the type of boss who isn’t willing to acknowledge or learn from their mistakes. Instead, they rationalize missteps by placing that blame on others. He is a glory seeker who puts fame and fortune above anything else, George says.
