A general led 5,000 people by using the Hawthorne Effect: tell someone they're good, and they'll believe it and perform better. Positive feedback creates a self-fulfilling prophecy that shapes how people see themselves and what they do.
Chapters
If you tell somebody that they're good, they're going to think that they're good, they're going to act like they're good, and they're going to get better. It's just like a child. If they're in school and you tell them that they're good, they're going to try and raise to that level of expectation wherever you set it. So this, this self-fulfilling prophecy known as the Hawthorne Effect is the whole idea. And there are so many examples I could give, but, you know, basically is back to dealing with people. Being positive is going to have them raise their expectations. They're going to try harder. They're going to get better just because of the environment that you have created.
