"Scientific evidence would have assisted the jury in deciding whether dissociative amnesia could be accurately diagnosed in a given person (such as the alleged victim), absent corroborating evidence from the past. Because of the admission of Frye-tested evidence on repressed memory, Fr. Shanley was convicted based solely on memories of abuse that the plaintiff “recovered” after years of dissociative amnesia. Given this, we cannot assume that the trier of fact would be able to ferret out the difference between the conjectures of experts and reliable scientific evidence."
