rmt1, interesting visual. I can see the bell curve in my mind. Acceptable Witnesses are within 2 standard deviations of the mean. Outliers are axed.
Fading albatross describes a situation in which a single data point becomes self-aware, of not only his position in the normal distribution, but also the entire distribution and the fate of the outliers.
Those hugging the mean are the most indoctrinated and very easy to manipulate. These data points are not very self-aware. The farther you move away from the mean, the less indoctrinated and the more danger the Society sees. Those in the 3rd standard deviation tend to talk. That is a danger sign to the Society. Once you are an outlier, you are a problem. Cue the witch hunts and the loyalty question.
The true sheep cluster together on the mean. As sheep do.
Anyhow, fun idea, rmt1!
