The Black Swan Theory

The Black Swan Theory, developed by Nassim Nicholas Taleb, refers to rare and unpredictable events that have a significant impact on markets, economies, or society. These events are often considered outliers because they fall outside of normal expectations and are extremely difficult to predict. Despite their rarity, black swan events can have devastating consequences, and Taleb argues that many risk models underestimate the likelihood and impact of such events.

Example

The 2008 financial crisis is often cited as a black swan event because it was largely unforeseen and had a massive impact on global financial markets.
