What's one of the most dangerous phrases that you can hear a leader utter? "I already know that..." Why is it so worrisome when we hear those words? It suggests that the individual believes that their state of knowledge on that subject is settled and complete. Therefore, they might not be open to learning new things, to questioning what their assumptions, and to considering the fact that they just might be wrong. We want leaders to at least consider the possibility that they are mistaken, or that changing circumstances make old assumptions outdated. The next time you find yourself thinking, "I already know that," I encourage you to ask instead, "What questions might I ask that could spur additional learning on this subject? How might I benefit from reconsidering my views and assumptions here? What could I be missing?"
