Psychology Prof. Nancy Steblay spoke with the Pittsburgh Post-Gazette about the reliability of eyewitness identification of criminal suspects. Steblay, who is a leading national expert on eyewitness identification, told the paper that the practice of showing a witness one photo at a time is more reliable than having witnesses look at an array of photos at once. Steblay said that a sequential process, “although it’s not perfect, it’s far superior – significantly superior – to the simultaneous procedure” because the witness is forced to compare the memory of the suspect to a single photo. The end result, she said, is a more absolute judgment. Read “New Pittsburgh public safety director spars with district attorney on eyewitness IDs.”
