Greg Stevenson explains how power isolates you from honest feedback. As you rise, people soften their criticism to stay in your good graces, leaving you making big decisions on incomplete information. A room full of agreement is a warning sign.
At some point near the top, people stop telling you the truth. Not because they're dishonest. Because you became powerful. And power makes honesty expensive for the person offering it. So the feedback to you softens. The room agrees a little too quickly. And you end up making the biggest decisions of your career on the most filtered information you've ever had. The higher you go, The harder the truth is to reach, and the more you need it, of course. If everyone around you is comfortable, that isn't a good sign. So who in your world is still willing to tell you the thing you don't want to hear?
