Have you ever met with an accomplished executive or manager and discover, once the conversation shifts to a subject area outside of the person's expertise, that this usually insightful person has turned into Ted Turner?
Do you ever wonder why CEOs are prone to buy dubious management fads that have Flavor of the Month stamped on the cover?
I suspect that these hard-nosed decision makers are especially prone to misjudgment when confronted with social science-related subjects, such as diversity and affirmative action. Unfortunately, there are plenty of "experts" willing to encourage those misjudgments if sizable amounts of money are involved.
This is not meant to mock. Their stumbles are a reminder to all of us that a combination of humility and skepticism may be needed when we step outside of our zones of knowledge.
