Excerpt from the Harvard Business Review -- "On average, those who underrated their skills were above average in their overall coaching effectiveness (reaching the 57th percentile). Those who had overrated themselves, however, were significantly below average, reaching only the 32nd percentile. ... incompetent people fail to recognize their own deficiencies and don’t recognize the skill in others. The lower an individual is on any scale of measurement, the more out-of-touch they tend to become."
