Is Eyewitness Testimony Inherently Unreliable?
Quote:Even after hearing the statistics, we are reluctant to distrust a sincere eyewitness, but decades of research show that memory is neither precise nor fixed. For instance, we would expect a moment of high stress to focus the mind and sharpen recall, but the opposite is true. Violence, stress, and the presence of a weapon during an incident actually weaken memory. Racial differences between the witness and the suspect can impair identifications. Unconscious transference, or confusing someone seen in one place with someone seen in another place, is common. Identification can also be impaired by how long the witness is exposed to the suspect, the delay between the incident and the identification, and post-event information, such as feedback from the police or other witnesses.
