> 20% of PhD-granting institutions in the United States supplied 80% of tenure-track faculty members 80:20 The Pareto Principle at work. All these figures show is that universities have the usual distribution of quality.
the Pareto principle doesn't really provide a lot of insight into process: https://www.technologyreview.com/2018/03/01/144958/if-youre-...
Their model has a set of agents with a 'talent' normally distributed between 0 and 1 (mean 0.6, SD 0.1). Each agent gets a random series of doubling and halving events. The doubling is applied with probability = 'talent'.
The lengths of the series of events have an exponentially decreasing distribution (four longer is x10 less probable, approximately). The application of these series of events to the agent is supposed to simulate a life history of random opportunities, exploited according to talent.
BUT...
Half the events are losses, half the events are possible (Ponly win with luck.
