Fractal Distribution
Fractal Distribution
A pattern where, as a quantity (like wealth) increases, the number of instances exhibiting that quantity or greater decreases according to a power-law relationship.
Fractal Randomness
Fractal Randomness
A way to think about randomness in large-scale events. It shows that extreme events follow patterns rather than being truly random.
Power Law
Power Law
A mathematical relationship where a quantity changes exponentially relative to a factor. A key characteristic of Fractal Distribution.

Study Notes
Introduction to Fractal Randomness
- Fractals are a way to think about randomness and how it affects large, unpredictable events
- They don’t eliminate these events but make them more understandable and help us account for them.
The Logic of Fractal Distribution
- Fractal Distribution: If wealth doubles, the number of people with that wealth or more is reduced by a power of two.
- This "power" is the main property of fractals and it affects how we think about and model events.
- This means that extreme events are not just random, but follow a pattern.
Fractal Distributions in Real-World Phenomena
- Examples: Words, website hits, and books all follow a fractal distribution.
- This means, for instance, that the number of books selling over a million copies is drastically less than those selling 250,000 copies.
Implications of Fractal Randomness
- Scalability: We can make inferences about things we don’t see in our data, recognizing the possibility of extreme events.
- This means that just because we haven’t seen a book sell 200 million copies doesn't mean it’s impossible.
- Unbounded Inequality: We can expect there to be people with even more wealth than we can currently imagine, though the probability becomes smaller.
The Relationship Between Fractals and Black Swans
- Gray Swans: Fractals help us understand and quantify many Black Swan events, making them “gray” swans, but not all.
- Epistemic Opacity: Even with fractals, there are events we can't fully anticipate.
- Fortuit vs. Hasard: This concept of irreducible uncertainty is not a new idea and can be traced back to Arabic origins.
Learning from Mother Nature
- The Black Swan is a book that explores the implications of fractal randomness on our understanding of the world.
- It helps us think about how to deal with uncertainty in a way that makes us less susceptible to surprises.
- The Role of Data: We need to be careful about assuming a predictable and Gaussian world, as real-world data often does not fit those models.
- The Importance of Inquiry: We should focus on scientific approaches that help us learn from our mistakes and avoid being "suckers" to unpredictable events.
