Why do people think about someone right before they call, for example, or have a feeling something is about to happen before it does? It may be due to something called collective consciousness - a term used by certain scientists to describe the practice of humans, and animals, sharing behaviours and ideas with each other telepathically. The Hundredth Monkey Phenomenon", for example, was an idea put forward by South African zoologist and ethologist Lyall Watson and his scientific author colleague Lawrence Blair in 1975. During the 1950s, macaques on the island of Koshima learned to wash sweet potatoes and explicitly passed this skill onto younger members of the group. This behaviour then spread and was observed on neighbouring islands among groups of macaques who had never [come] into contact with each other. [Watson and Blair] chalked this up to the monkeys sharing a collective consciousness, often referred to as a shared mind or hive mind, in which the practices were shared telepathically. More recently ... blue tits ... taught themselves [to] break into milk bottles and drink the cream from the top. Similar groups of the same [non-migratory] species [later] exhibited the same skills in other countries throughout Europe and Asia. A science journal in 2010 published [the results of experiments] by Professor Daryl Bem, a physicist from Cornell University, that [indicated] humans have similar psychic abilities supposedly seen in the birds and monkeys. Professor Bem carried out nine different experiments involving more than 1,000 volunteers and all but one came down on the side of these so-called psychic theories.
