Have you ever shouted, “hellooooo” from the top of a hill and heard your greeting echo return to you? It’s fun. But if you wanted feedback on an idea, you wouldn’t use the same approach. Because an echo is just your own words, bounced back to you. If you only collaborate with people who agree with you, you’ll have much the same experience. You’ll be working in what’s known as an echo chamber. When you surround yourself with yes people, your ideas and views won’t be challenged. And you’ll contribute to a workplace culture in which people don’t feel safe to disagree. Understanding the dangers of echo chambers and how to overcome them will help you avoid making choices that anger the gods …or pursue innovation in the workplace, if that’s more relevant to your sector.
