In 1952 on the island of Koshima, a primatologist was leaving sweet potatoes on the shore for the monkeys to eat. One smart monkey, a one and a half year old named Imo, began washing the sand off her potatoes in a brook. You can imagine how much better this insight on her part made the potatoes taste! Next, Imo's playmate was observed washing potatoes. Then her mother, then another peer. In four years, three more of her relatives and four members of another macaque group were washing their food. The primatologist realized he was watching the way new ideas spread in society! Infants in the next generation saw their mothers washing potatoes, and virtually all the next generation, both male and female, grew up washing their food, but not the older males! Older males were resistant to the new idea, refusing to wash their food even when older females made the change. It was as if a new idea from a female, or perhaps a lower-ranking member of macaque society, were rejected by older males even though it was a good idea. They seemed to choose eating sand rather than admitting Imo was smarter than they were.
1952年，在儿岛上，一位灵长类动物学家正把甜的马铃薯留在岸边以便猴子们食用。一个只有一岁半叫imo的聪明的猴子，开始用溪水洗掉她马铃薯上的沙子。你可以想象她的这一做法可以使马铃薯尝起来是多么的美味。 接下来，Imo的玩伴被观察到清洗马铃薯。接着是她的妈妈，和她的另一个同龄人。在四年之中，与其有联系的另外三个恒河猴及另外一个恒河猴群中的四个成员也开始清洗他们的食物。灵长类动物学家认识到他正在观察一项新思想在社会中的传播。 下一辈的婴儿猴子看到他们的母亲清洗马铃薯，事实上，所有的下一代，无论公母都在清洗食物中成长，但是不包括年长的雄性恒河猴。年长的雄性恒河猴抵触新的思想，拒绝清洗他们的食物，即使年长的雌性恒河猴已经开始改变。 这就像一个来自雌性恒河猴的新主意（雌性恒河猴在恒河猴的种群中 也许处在一个较低的阶层）即使这个主意是个好主意仍会被年长的雄性恒河猴拒绝一样。他们更像是宁愿吃沙子也不愿承认Imo比他们要聪明。
