Etymology
The concept was first mathematically described in the 18th century, though the specific name became popular in the 20th century. It is also known as the Monte Carlo fallacy, named after a famous 1913 event where a roulette ball fell on black 26 times in a row, costing gamblers millions as they bet against the streak.
