The E-meter was created in the 1940s by the American inventor W. Matheson and was called the Matheson electropsychometer. The E-meter was a modified ohmmeter used to measure the electrical resistance of the human body to direct electric current.
The invention of large profits did not promise until Matisson began to collaborate with the psychoanalyst Hubbard.
Hubbard, who was quick and disposed to himself, managed not only to file a patent for an invention (of course in his own name), but also found a use for the device. Later, the device was renamed the Hubbard electropsychometer, and the inventor was left out of the box, since the patent was filed for Hubbard.
It must be said that Charismatic Hubbard was not only a psychologist, but also the creator of a new religious movement called Dianetics. The essence of the teaching was that through special practices you can achieve anything: curing diseases, wealth, fame, etc.
Matheson's electropsychometer was adapted by Hubbard for the needs of his new teaching. He comes up with a new medical practice using the E-meter and begins to actively market the device to his followers.
However, in the 60s, the police became interested in the sect and they were accused of fraudulent activities about allegedly curing about 70% of all physical and mental illnesses with the help of the E-meter. The agency also noted that this device does not contribute to the treatment of those diseases for which it is recommended. A lengthy trial with a jury concluded that the information about the usefulness of the E-meter in the treatment of diseases is distorted.
This is what the research of the device by scientists testifies: this type of device is able to register only one characteristic of the central nervous system - excitement, lie detectors, for comparison, register from 4 to 9 physiological parameters, and even despite this, their work is not always valid, it is put questioned by some experts and not recognized by some courts. The German scientists who became interested in the device somehow later called the device "scientifically useless" in their report.
Hubbard and his Scientology followers developed the practice of the E-Meter to support auditing. Large sums were received for the E-meter and the auditing session on it. The Church of Scientology has about 20, 000 followers in more than 100 countries and is still sold an E-Meter (the latest Modell Mark Super VII Quantum E-Meter), which costs 7, 428 euros, although its production cost is no more than 100.
