The Australian Institute of Criminology, Australia's official crime research agency, advises parents of missing children not to resort to using psychics who approach them. Former FBI analyst and profiler Clint Van Zandt has criticized the use of psychic detectives and has stated that "What happens many times is that professed psychics allow themselves the benefit of 20/20 hindsight. After the case is solved, they make their previously vague predictions somehow fit the crime and the criminal." A detailed 2010 study of Sylvia Browne predictions about 115 missing persons and murder cases has found that despite her repeated claims to be more than 85% correct, "Browne has not even been mostly correct in a single case."
