I can only recognize the occurrence of the normal curve … as a very abnormal phenomenon. — Karl Pearson (1901) Widely believed and rarely questioned is the notion that human characteristics ...

A bell curve is a graph used to visualize the distribution of a set of chosen values across a specified group that tend to have central, normal values that peak, with low and high extremes ...

The bell curve model limits the quantity of people at the top and also reduces incentives to the highest rating. Given the arbitrary five-scale rating and the fact that most people are 2,3,4 rated ...

Human performance, by this account, does not often fit the bell curve or what scientists call a normal distribution. Rather, it is more likely to fit what scientists call a power distribution.

It's possible, but not common. This is a good time to revisit the difference between normal and average. Picture a nice bell-shaped curve and remember that for a given characteristic the normal ...
