The difference between a definition and a determination is explained by Stephen Bungay
Kate, Margaretta, and Leah. Kate age 12 and Margaretta 15 claimed to hear strange rapping noises in their bedroom.
They convinced a few folks that they were getting messages from spirits. Soon they hit the road, managed by big sister Leah, who was in her mids. Several eminent scientists, including biologist Alfred Russell Wallace and chemist Sir William Crookesbecame interested in spirit communication.
Both claimed that they had scientific demonstrations for the existence of psychic phenomena such as spirits tilting tables. Inthe sisters confessed that they had produced the raps by cracking their toe-joints and that they made bumping noises by fastening an apple to a string under their petticoats and surreptitiously bouncing it off the floor.
They tried to recant but it was too late. The cat was out of the bag. This would not be the last time an eminent scientist was tricked by a subject of psychical research. Crookes became interested in spiritualism after the death of his brother. The American chemist Robert Hare at first agreed with Faraday but then did his own investigation.
He developed an apparatus he called the Spiritoscope, designed to detect mediumistic fraud. In the process of testing his machine, he became a spiritualist convert. Some might still be due to spirits.
And, of course, there could be dozens of ways a conjurer might produce table movements or the illusion of table movements. That emotional experience ignited an interest in testing psychic phenomena in several eminent scientists, including Wallace, Hare, and Crookes.
Unfortunately, such an emotional investment easily fuels a pro-psychic bias that makes it difficult to do adequately controlled experiments on psychic phenomena. It has been a common error made by eminent scientists in the history of parapsychology to believe that being intelligent, knowing how to conduct a scientific experiment, and being diligent against deception, cheating, or self-deception would be sufficient to guarantee a fair test of psychic powers.
This became apparent during two of the first scientific experiments designed and supervised by several eminent men for the first society formed specifically to study psychic phenomena.
The goal of the society, in part, according to Sidgwick was to drive the objector into the position of being forced either to admit the phenomena as inexplicable, at least by him, or to accuse the investigators either of lying or cheating or of a blindness or forgetfulness incompatible with any intellectual condition except absolute idiocy.
Barrett introduced a method for testing telepathy that was popular for more than a century, though it is rarely used anymore by scientific investigators:You can use the free response questions and scoring guidelines below as you prepare for the AP Biology.
