A twelfth-century-bc Chinese king consulted an oracle and was told his lucky charm would not be a tiger, dragon, bear, or leopard but rather a wise counselor. He soon came upon a sagacious old man fishing in the river and conscripted him into service. It is said the man’s virtue was such that he fished not with a hook but with a straight piece of iron; acknowledging his integrity, fish impaled themselves voluntarily.

When Apple released its Shuffle feature for iPods, users were deceived by the true randomness of its playback; songs from the same album or artist were often grouped by chance. Complaints led Steve Jobs to alter the device’s programming and begin offering Smart Shuffle, which allowed users to adjust the likelihood of hearing similar songs in a row. “We’re making it less random,” he said, “to make it feel more random.”

“The contempt of risk and the presumptuous hope of success are in no period of life more active than at the age at which young people choose their professions,” wrote Adam Smith in 1776. “How little the fear of misfortune is then capable of balancing the hope of good luck.”

“The die,” wrote geographer Pausanias circa 150, “is the plaything of youths and maidens, who have nothing of the ugliness of old age.” 

Suetonius reported that Caligula often cheated when playing dice. The emperor once interrupted a game to go into the courtyard, where he spotted a group of rich knights passing. He had them arrested, stole their goods, then “resumed the game in high spirits, boasting that his luck had never been better.”

In Serbian oral tradition, fate often appears written on foreheads. A typical story tells of a man on the run from a plague personified as a woman. “It is not fated that I should kill you,” she says on catching him and seeing his forehead’s inscription. “You’ll be killed by a turtle.” Later, the man mows a field. His scythe hits a turtle, ricochets off its shell, and slices his leg. He dies soon after from blood poisoning.
