Mind-reading. Foretelling the future. The ability to move objects without touching them. Being able to see distant and hidden objects with the mind. To most people, this sounds like the high points of the act of an illusionist, a person who uses trickery to baffle and confuse an audience while performing stage magic to achieve uncanny feats. But we all know these things really are impossible. Aren’t they?

The concept of what has become known as Extrasensory Perception (ESP) has existed for a century. This notion claims that certain seemingly impossible feats can be produced not by tricks but by using the human mind in ways that still aren’t understood. Instances of telepathy, precognition, telekinesis, and remote viewing aren’t confined to magic shows. It’s well known that some people claim to have these abilities. What is less well known is that almost from the time the term ESP was first used, there have been attempts to use scientific investigation to find out whether they are real.

In the beginning, these experiments were conducted by individuals or small organizations regarded as cranks by most members of the mainstream scientific community. Their findings were generally ignored, but that became more difficult in 1995 when previously secret documents were declassified. These revealed that a series of experiments on ESP had been funded by the CIA and DIA that cost millions of dollars and were carried out by respected scientists at Stanford Research International (SRI) in Menlo Park, California over the course of more than 15 years.
