by Nassim Nicholas Taleb

The core ideas of The Black Swan, each in under a minute, written in our own words. Want the full depth? Get the book.

1. IDEA 1 OF 6

   Rare events dominate

   A few unpredictable, high-impact events shape history and markets.

   Models built on averages miss them.

2. IDEA 2 OF 6

   Hindsight makes them seem obvious

   After a black swan, people invent stories that make it look predictable.

   It wasn't.

3. IDEA 3 OF 6

   Mediocristan versus Extremistan

   In some domains (height) no single case matters much; in others (wealth, book sales) one case can dwarf the rest.

4. IDEA 4 OF 6

   Beware of the narrative fallacy

   We love tidy stories and ignore randomness.

   Be suspicious of clean explanations.

5. IDEA 5 OF 6

   Absence of evidence

   Not seeing a risk doesn't mean it's not there.

   Many dangers are silent until they hit.

6. IDEA 6 OF 6

   Prepare, don't predict

   Since you can't forecast black swans, build exposure to positive ones and protection from negative ones.
