Judgment—the ability to combine personal qualities with relevant knowledge and experience to form opinions and make decisions—is “the core of exemplary leadership” according to Noel Tichy and Warren Bennis (the authors of Judgment: How Winning Leaders Make Great Calls). It is what enables a sound choice in the absence of clear-cut, relevant data or an obvious path. To some degree we are all capable of forming views and interpreting evidence. What we need, of course, is good judgment.
