I’m trying to understand what this means. I know the Pareto Principle from two contexts:

1. Jordan Peterson bringing it up all the time as a vague hand wave to make his disdain for communists sound scientific
2. My old manager who learned about it in some bullshit professional development course

Because of the latter context, I’ve spent a fair amount of time trying to make this “principle” measurable and rigorous in a real business context and it’s just a fool’s errand. If you start out with a conclusion, it’s easy to map the 80/20 rule onto preexisting data, but trying to actually use it to create predictive models, I found it useless.
