The Hundredth-Monkey Effect

The hundredth-monkey effect is a supposed phenomenon in which a learned behaviour spreads instantaneously from one group of monkeys to all related monkeys once a critical number is reached. By generalisation it means the instantaneous, paranormal spreading of an idea or ability to the remainder of a population once a certain portion of that population has heard of the new idea or learned the new ability.

The story of the “Hundredth Monkey Effect” was published in the foreword to Lawrence Blair’s Rhythms of Vision in 1975. The claim spread with the appearance of Lifetide, a 1979 book by Lyall Watson. In it, Watson repeats Blair’s claim. The authors describe similar scenarios. They state that unidentified scientists were conducting a study of macaques monkeys on the Japanese island of Koshima in 1952. These scientists purportedly observed that some of these monkeys learned to wash sweet potatoes, and gradually this new behavior spread through the younger generation of monkeys—in the usual fashion, through observation and repetition. Watson then claimed that the researchers observed that once a critical number of monkeys was reached —the so-called hundredth monkey—this previously learned behavior instantly spread across the water to monkeys on nearby islands.

This myth has a lot of holes, but I believe there’s an underlying truth to it, none the less.
