1. Concentration claim
Across cities, bodies, money, language, and relationships, outcomes and usage repeatedly concentrate in a small share of inputs — ratios vary; the skew repeats.
2. Hard anchors
- Vilfredo Pareto — land/wealth concentration observation (late 1800s); generalized later as 80/20. https://en.wikipedia.org/wiki/Pareto_principle (use carefully; prefer Britannica or academic summary if linking)
- Zipf’s law — word frequency skew. https://en.wikipedia.org/wiki/Zipf%27s_law
- Microsoft reliability — ~20% of bugs → ~80% of errors (Ballmer memo, 2002). https://www.crn.com/news/security/18821726/microsofts-ceo-80-20-rule-applies-to-bugs-not-just-features
- Soft claims (sleep, injuries, support circle): pattern / commonly reported — no “researchers say” without names.
2b. Field 80/20 examples

3. Original observation (only-on-8020)
Personal concentration scavenger list: one-week reader challenge — pick 3 domains, write the few vs the many — not a 21-step life system.
4. Ignored majority
Optimizing rare events (restaurant meals, unused gadgets, fantasy wardrobe) while defaults, arterials, and inner circle drift.
5. Composite policy
Most examples are general observations — mark soft ones; no invented named people.
6. Vital few (of the article)
Pattern recognition skill; ~16–18 sharp examples max; mixed endings (not identical Q&A on every item).
7. Device budget
“What concentrates? / What can we learn?” on ~half only. ≤1 8020 move at end.
