Every culture has a number considered unlucky because of superstitions. In the United States it's 13. In South Korea, it's four.
The reason behind the fear of the number four, known as tetraphobia, lies in the way it sounds. The Korean word for "four" sounds much like their word for "death."
Tetraphobia is fairly common across many Asian cultures and far surpasses Western propensity to triskaidekaphobia, the fear of the number 13. The superstition permeates through many aspects of society in these cultures. Many elevators in South Korea, for instance, skip the number four or use the letter "F" in place of the number four to represent the fourth floor.
Americans competing in Pyeongchang are learning that you don't need to believe in the "curse of four" to be doomed by the single-digit menace. And given these Team USA athletes' results at the 2018 Winter Games, they may leave South Korea with their own fear of four.
