I learned about cargo cults a while ago, and today happened upon a mention of them in this fun and interesting commencement address Richard Feynman gave at Caltech back in 1974. Go read it.
Wikipedia has a more details on cargo cults :
Posted on February 1, 2005 10:31 PM. Filed under: strange stuff.The term cargo cult is a reference to aboriginal religions that grew up in the South Pacific, especially New Guinea and Melanesian islands, initially in the mid 1800s, but most commonly in the years during and after World War II. There was no one Cargo Cult so this proper name is a misnomer — no one who participated in a cargo cult actually knew that they were doing so.
The vast amounts of war materiel that were air-dropped into these islands during the Pacific campaign against the Empire of Japan necessarily meant drastic changes to the lifestyle of these islanders as manufactured clothing, canned food, tents, weapons and other useful goods arrived in vast quantities to equip soldiers — and also the islanders who were their guides and hosts. When the war moved on, and ultimately when it ended, the airbases were abandoned and no new "cargo" was then being dropped.
In attempts to get cargo to fall by parachute or land in planes or ships again, islanders adopted a shallow version of the same practices they had seen the soldiers, sailors and airmen use. They carved headphones from wood, and wore them while sitting in control towers. They waved the landing signals while standing on the runways. They lit signal fires and torches to light up runways and lighthouses.
The cultists thought that the foreigners have some special connection to the ancestors, who were the only beings powerful enough to spill such riches. By mimicking the foreigners, they hoped to bypass them. [continue]
