The lingering shadow cast by the return Black Swan December 2025

The problem of induction casts a deep shadow that humans cannot avoid when trying to understand the world. The fact that the future cannot be guaranteed with certainty no matter how many observations are accumulated carries both philosophical and practical weight. The existence of black swans cannot be denied even if one sees thousands of white swans, and events lurk that can never be captured by an extension of experience. There lies the quiet arrogance of human beings who try to infer an infinite future from finite experience.

Eighteenth-century Hume sharply verbalized this problem, showing that we have no basis for believing that "the sun will rise again tomorrow" except through repetition of the past. However, the assumption that "nature will behave the same way in the future," which supports this inference, again depends on induction. In this way, induction continues to go in circles without being able to justify itself, supporting everyday thinking but carrying with it the uncertainty of scaffolding.

Taleb reads this classical problem as a modern theory of uncertainty and presents it as the structure behind the black swan. Just as the calm of the past hundred years does not guarantee the next year, significant fluctuations come suddenly without leaving a shadow on past data. Models and forecasts are bound to "yesterday" to which they can refer, and are often blind to the most important dangers. That is why extreme events quietly gather strength outside of statistics, and one day, lightly overturn our assumptions.

In the past, people had the attitude that what we don't know is what matters, and that we build our knowledge from disproofs. But somehow we have become more inclined to lean only on what is known and to disregard the unknown. By escaping into a reassuring narrative, silent evidence that has the potential to shake the world is overlooked. The danger of induction is thus slowly eroding our judgment.

The problem of induction is not an abstraction placed only on the shelves of philosophy, but continues to be deeply involved in scientific reasoning, economics, social institutions, and financial engineering. That is why Taleb tells us that we should not pursue accuracy in predicting the future, but rather build structures that are less likely to break down when errors occur. The future is not necessarily an extension of yesterday. The black swan lurking on the other side of silence will always betray our certainties and repaint the contours of the world. The shadow of induction lingers each time and quietly continues to speak of the need for moderation and preparedness.
