The black swan theory or theory of black swan events is a metaphor that describes an event that comes as a surprise, has a major effect, and is often inappropriately rationalized after the fact with the benefit of hindsight.

This is the problem of induction. Suppose we want to put the hypothesis that all swans are white to the test. We come across a white swan. We cannot validly argue (or induce) from "here is a white swan" to "all swans are white"; doing so would require a logical fallacy such as, for example, affirming the consequent. [3]
The observation of these black swans contradicts the law "All swans are white", but even if there were no black swans, the law would still be falsifiable, because identifying a swan and observing the color black would remain possible. Informally, a statement is falsifiable if some observation might show it to be false.
The book asserts that a "Black Swan" event depends on the observer: for example, what may be a Black Swan surprise for a turkey is not a Black Swan surprise for its butcher. Hence the objective should be to "avoid being the turkey", by identifying areas of vulnerability in order to "turn the Black Swans white".
