Are psychics ever actually useful in missing persons investigations?
No. Academics have repeatedly tested the abilities of psychics to provide any useful information in a crime investigation, and the results are damning. A British study published in 1996, for example, pitted self-proclaimed psychics against undergraduate psychology students. Each participant was handed an item that was involved in a solved crime, such as a scarf or a shoe, and the subjects simply uttered whatever notions popped into their minds. They were also given a list of statements about the crimes, only some of which were true. The psychics were no better than the students at making predictions, and neither group performed better than chance. Those results have been replicated in dozens of studies.
Theres one finding that comes up in nearly all of the studies: Psychics make lots of predictions, far more predictions than the control groups. Thats no coincidence. After the facts of the test cases are revealed, the psychics typically ignore their inaccurate predictions and emphasize their more relevant guesses. The more predictions you make, the more likely you are to get a random hit. But, taken as a whole, psychics visions are true just as often as anyone elses.
