J. Robert Clinton bases his mentoring model (The Mentor Handbook) on “600 case studies of [serving] leaders” (Clinton J R 1991:1-1). Most of these studies reveal “between 3 and 10 significant people” who served as mentors in a leader’s life. A major purpose of the model is, of course, to limit dropout from Christian leadership. But consider this. How many “significant people” were there in the lives of those who dropped out? And how many of those included in the case studies will YET drop out? We have no idea. Therefore what do the 600 case studies prove? At first glance, 600 case studies has a convincing ring to it -- yet there is a fallacy at the heart of it, which is the subject of my next post. QUESTION: To what degree are the data invalidated in this example? Completely?
