Understanding Complexity in Systems: A Beginner's Guide
Complex systems like markets display unpredictable behaviors, contrasting predictable complexity in systems like airplanes.
What was corrected
Article cited specific studies, presentations, and statistics for real companies, researchers, and events that, on independent verification, do not exist or materially misrepresent the documented timeline/findings.
Removed the unverified study citations and unverified statistics while preserving the real underlying facts (Lilly's real adaptive-trial-design push, Curitiba's real transit design philosophy, Sornette's real precursor-signal research, Bar-Yam's real COVID-era policy analysis, and the blackout's real scale and cascading-failure mechanism).
Why this is better
Real researchers, companies, and events were used as anchors for unverified studies, conference presentations, and statistics - the Barabasi-Albert 1999 Science paper and the P&G/Lafley/Huston-Sakkab 2006 HBR citation in the same article both verified as fully accurate.
