I just reread the concept of a black swan and what it means, and I realize it is truly important for those who want to understand the market. This term was introduced by thinker Nassim Nicholas Taleb, referring to extremely rare, unexpected events that we cannot predict in advance.

The brilliance of Taleb is that he emphasizes traditional statistical models are completely powerless against these events. Why? Because those models rely on past data, but black swans have never occurred before, so how can they be predicted? He says very well: just because the past is safe doesn’t mean the future will be.

Interestingly, the term "black swan" has a historical origin. Europeans long believed all swans were white, so black swans were considered nonexistent. Until they discovered them in Australia — an event that completely overturned expectations and theories at the time. That’s why a black swan is meaningful: it symbolizes what we have never seen before, the possibilities we inadvertently overlook.

The name "black swan" is also very clever — it creates a strong visual image that easily evokes unusual, unpredictable events. That’s why Taleb chose this name for his book.

But what is the most important message Taleb wants to convey? It’s that when facing uncertainty, we often make logical errors and create our own explanations to feel at ease. We think we can control everything, but in reality, the world doesn’t operate linearly. Most major changes are not smooth and often come unexpectedly.

Therefore, understanding what a black swan means will help us better prepare mentally for unpredictable fluctuations in life, especially in investing.
