You’ve (Likely) Been Playing The Game of Life Wrong
Summary of Content
This video explores how many real-world phenomena and systems do not follow the familiar normal distribution (bell curve) but instead follow power laws, which have very different and often counterintuitive properties. It explains the implications of this for understanding risks, rewards, and strategies in various domains, including economics, natural disasters, and human behavior.
Key Concepts and Storyline
Normal Distribution vs. Power Laws
- Normal distributions cluster data around an average with rare extreme outliers (e.g., human height).
- Power laws have no characteristic scale, produce heavy tails, and extreme events are much more common than expected.
- Examples of power laws include:
- Income distribution
- Size of wars
- Earthquake magnitudes
- Forest fires
Vilfredo Pareto and Income Distribution
- Pareto discovered that income distribution in multiple countries follows a power law.
- On a log-log plot, income distribution forms a straight line with a specific gradient (~-1.5).
- This means a few people earn disproportionately more, a pattern that persists universally.
Casino Coin Toss Games Illustrating Distributions
- Game 1: 100 coin tosses, $1 per head, expected payout $50 (normal distribution).
- Game 2: Multiplicative winnings with 1.1x or 0.9x per toss, payout distribution is log-normal, with a long tail but capped downside.
- Game 3 (St. Petersburg Paradox): Payout doubles until first heads, expected payout is infinite, follows a power law with no finite average or variance.
Power Laws and Criticality in Nature
- Many natural phenomena (earthquakes, forest fires, magnetism) show power laws because they operate near a critical point or phase transition.
- At criticality, systems become fractal and scale-free, with no intrinsic scale.
- Examples:
- Magnet losing magnetism at Curie temperature shows fractal domain structures.
- Forest fires self-organize to a critical state, producing many small fires and rare massive megafires.
- Earthquakes follow power laws in their energy release and frequency.
Self-Organized Criticality
- Some systems naturally tune themselves to criticality without external control (e.g., forests, sandpiles, earthquakes).
- The sandpile model demonstrates avalanches of all sizes with power law distributions, similar to forest fires and earthquakes.
- This universality means vastly different systems behave similarly near critical points.
Implications for Risk, Strategy, and Human Systems
- Power law distributions imply rare, extreme events dominate averages and outcomes.
- Insurance must account for rare catastrophes; failure to do so can cause bankruptcies.
- Venture capital, publishing, and entertainment industries rely on power laws where a few hits generate most returns.
- Businesses like restaurants and airlines, which depend on consistent averages, cannot rely on power law dynamics.
- Understanding whether you’re in a normal or power law environment is crucial for strategy:
- Normal: focus on consistency and average performance.
- Power law: focus on persistence, taking many bets, and aiming for rare outsized successes.
Networks and Preferential Attachment
- The internet’s link structure follows a power law due to preferential attachment (new nodes link to popular nodes).
- This “rich get richer” effect creates extreme inequality in connectivity and influence.
Broader Applications
- Power laws appear in:
- DNA sequencing
- Ecosystems
- Mass extinctions
- City populations
- Stock market crashes
- Wars
- The world is poised at a critical state where small actions can have disproportionately large effects.
Final Thoughts
The unpredictability of power law systems means you cannot know which bet or action will yield massive success. Persistence and making many intelligent attempts increase chances of hitting a “wild success.” Awareness of the type of “game” or system you are playing in helps adapt your behavior accordingly.
Strategies and Key Tips
- Identify the distribution type (normal vs. power law) governing your environment.
- In power law environments:
- Accept that most attempts will fail.
- Focus on persistence and making many attempts.
- Look for rare, outsized successes rather than average gains.
- Understand that averages can be misleading due to extreme outliers.
- Use insurance or risk management to protect against rare catastrophic events.
- In industries with power law dynamics (venture capital, publishing, entertainment), embrace risk-taking and diversification.
- Recognize the self-organizing nature of many systems and the inevitability of large-scale events.
- Leverage the preferential attachment effect early to maximize growth and influence.
