Nassim Nicholas Taleb

The trader and philosopher who wrote Fooled by Randomness about luck and uncertainty

Example

Taleb draws on his experience in finance to explore how we misunderstand randomness

Randomness

The role of chance and unpredictable variation in outcomes

Example

We systematically underestimate how much of success and failure is due to randomness

Survivorship Bias

The error of focusing on winners while ignoring the many losers who tried the same approach

Example

Survivorship bias makes successful strategies look more reliable than they are

Alternative Histories

The many paths events could have taken that differ from the one that actually occurred

Example

Considering alternative histories reveals how much outcomes depend on luck

Narrative Fallacy

The tendency to construct stories that explain random events as if they were predictable

Example

Narrative fallacy creates false sense of understanding about what caused outcomes

Hindsight Bias

The belief after the fact that events were predictable when they were not

Example

Hindsight bias makes us think we knew what would happen when we could not have known

Skewness

Asymmetry in probability distributions where rare events have outsized impact

Example

Skewed distributions mean average outcomes differ greatly from typical outcomes

Black Swan

A rare high-impact event that is unpredictable but rationalized after the fact

Example

Black Swans are outliers that have massive consequences and cannot be forecast

Noise vs Signal

The distinction between meaningful information and random fluctuation

Example

We often mistake noise for signal seeing patterns in randomness

Monte Carlo Simulation

Using random sampling to model probability and understand possible outcomes

Example

Monte Carlo methods reveal the range of possibilities that could occur by chance

Nero Tulip

A fictional trader in the book who represents wise risk management and awareness of randomness

Example

Nero succeeds by being aware of what he does not know and managing tail risk

John

A fictional trader who represents overconfidence and vulnerability to randomness

Example

John succeeds by luck but attributes it to skill making him fragile to inevitable reversals
