Study Notes
The Crisis of 2008
- The 2008 financial crisis was not a Black Swan event.
- It was caused by fragility in systems built on ignorance of Black Swan events.
- The author considers the crisis uninteresting and not new.
Robustness and Black Swan Events
- The author argues that societies need to be robust to errors.
- He criticizes "idea books" and "actionable steps" that offer simplistic solutions.
- The author views "how not to go bust" as the most robust advice.
Randomness and Uncertainty
- The author distinguishes between "true" randomness and randomness caused by epistemic limitations.
- "True" randomness is called ontological uncertainty; the future doesn't depend on the past.
- "Epistemic limitations" are due to lack of knowledge.
Ergodic vs. Nonergodic Systems
- Ergodic systems are invariant to paths taken in the intermediate term, while nonergodic systems are sensitive to path dependency, meaning there is no long-term predictability.
- The author argues that the distinction between epistemic and ontic uncertainty is irrelevant in practice.
Preasymptotics and Preasymptotic Properties
- The author focuses on "preasymptotics," events that occur before a long-term equilibrium is reached.
- Theories often fail to account for preasymptotic conditions.
- Most statistical education focuses on asymptotic properties, but real life exists in the preasymptote.
Small Uncertainties and Large Impacts
- Even a small uncertainty in input parameters can have a large impact in complex systems.
- This is due to nonlinearities, where small changes can have amplified effects.
- This applies to areas like climate modeling, making accurate predictions challenging.
Computable vs. Incomputable Risk
- The author criticizes the division of risk into computable and uncomputable categories.
- He suggests that the probability of future events cannot be accurately measured.
- Catastrophic events are inherently absent from historical data, making it difficult to assess their true probability.
Stability and Risk Bias
- Data often underestimates potential volatility and risk.
- Historical events may seem less risky than they actually were, leading to surprises.
- This applies particularly to areas like epidemics and environmental risks.
Preasymptotics and Platonic Theories
- The author further criticizes reliance on Platonic theories that are valid only in idealized situations.
- Theories applied outside their asymptotic conditions may fail to accurately reflect real-world events.
- He emphasizes the importance of understanding preasymptotic behavior.
