So a couple of wrong predictions erase the umpteenth precise ones? A man builds a thousand bridges and sucks one cock so he'll forever be known as gay 
In 2010, the Skeptical Inquirer published a detailed three-year study by Ryan Shaffer and Agatha Jadwiszczok, examining Browne's predictions about missing persons and murder cases. Despite Browne's repeated claims to be more than 85% correct, the study reported that "Browne has not even been mostly correct in a single case." The study compared Browne's televised statements about 115 cases with newspaper reports, and found that in 25 cases where the actual outcome was known, she was
completely wrong in every one. In the rest, where the final outcome was unknown, her predictions could not be substantiated.
In a 2013 follow-up article, Shaffer reviewed more recent predictions by Browne, as well as predictions whose outcomes had been earlier classified as undetermined but were now largely resolved. According to Shaffer, Browne was
mostly or completely wrong in 33 cases and
mostly accurate in none.
