As you read, you’ll realize that these Nine Lies have taken hold because each satisfies the organization’s need for control. Large organizations are complex places, and a strong and understandable instinct of their leaders is to seek simplicity and order—not least because this makes it easier to persuade themselves and their stakeholders that they are moving toward their objectives. But the desire for simplicity easily shades into a desire for conformity, and before long this conformity threatens to extinguish individuality. Before we know it, the particular talents and interests of each person are seen as inconveniences, and the organization comes to treat its people as essentially interchangeable.

In this job, respect is always more important than being liked.

You can’t please everyone. Trying can be ruinous.

CEOs have to make incredibly unpopular decisions—lay people off, kill projects, rearrange teams. Often you’ll have to take decisive action, hurt people to save the company, to cut out a cancer. You can’t skip surgery because you don’t want to upset Team Tumor.

Delaying hard decisions, hoping problems will resolve themselves, or keeping pleasant but incompetent people on the team might make you feel better. It may give you the illusion of niceness. But it chips away at the company, bit by bit, and erodes the team’s respect for you.

Managing people is difficult because people are complex. In today’s high-pressure environments, it is very easy to get caught up in the fight for results and to forget about the complex human beings who are needed to produce them.

The lesson, and perhaps the irony, of Tsedal and Sebastian’s study is that executives who deferred to subordinates moved up the pecking order faster than those who refused to bend to their underlings’ will and wisdom: Leaders were granted more power because they gave it away. Yet deference and “flattening” the hierarchy aren’t always the right moves. The University of Michigan’s Lindy Greer shows that the best leaders are adept at “flexing” the hierarchy.

The relationships with others essential to activities such as parenthood, education and research are valued for themselves, not just for their consequences. Most humans are good at detecting instrumentality – the false bonhomie of the used car salesman, the cynical hypocrisy of the vote-seeking politician – and are repelled by it. There is a difference between the firm that promotes the welfare of its employees because its executives care, and the firm that promotes the welfare of its employees because its finance department has calculated the net present value of reduced staff turnover. And employees can usually tell which is which.
