We all have our echo chambers, but leaders have them more than most. And that’s a problem, because they undermine decision-making, are usually invisible, and can be tough to break.

The power that comes with being in charge can be a wonderful thing. It enables us to make decisions, direct activity and have an impact across a broader scale. But it isn’t just an enabler, because it also changes the people who wield it. Sometimes for the better, but all too often in subtle, hidden ways that make the job of being a leader much more difficult.
