The Myth of the Bell Curve
Josh Bersin about knowledge workers:
A “Power Law” distribution is also known as a “long tail.” It indicates that people are not “normally distributed.” In this statistical model there are a small number of people who are “hyper high performers,” a a broad swath of people who are “good performers” and a smaller number of people who are “low performers.” It essentially accounts for a much wider variation in performance among the sample.
