The more people feel unempowered, the more they long for heroes. Experts are one form of such hero. In this context there is a fine line between the distinctions of expert and authority. My writing and research over the past few decades positions me frequently to offer expertise to groups and leaders across a variety of contexts. I am part of the genre of experts who see an authetic expert as one who has asked and continues to ask more questions than most people in whatever domain of expertise we practice in.
The work of authetic expert is about engagement and empowerment, not domination and colonization.
