Final answer:
Nassim Taleb's theory is about black swans, which are rare and unpredictable events that have a major impact. These events disrupt our assumptions about the future and require a flexible approach. Examples of black swans include abrupt changes in technology or sudden sociopolitical shifts.
Step-by-step explanation:
Nassim Taleb's theory is about the concept of "Black Swans", which are unforeseen and outlier events that have a major impact. These events are extremely rare, but when they occur, they can be reasonably predictable in hindsight. For example, abrupt changes in technology or sudden sociopolitical shifts can be considered as black swans. Taleb argues that these events disrupt our assumptions about the future and highlights the need for humility and flexibility in our approach to the future.
