In examining children's testimony in light of information on child development, the authors indicate that children can and do give reliable testimony. Prosecutor reluctance to pursue cases that rely on children's testimony is often reluctance born of misunderstanding. Many child molesters are never brought to trial because prosecutors know juries are predisposed to doubt the testimony of children. Adults who doubt children because of false assumptions about their perception, memory, suggestibility, and truthfulness cannot fairly evaluate their testimony in the courtroom. Two basic questions are raised and discussed that concern whether children lie and whether children's memories are easy to manipulate, and the authors conclude that child testimony must be believed.
