The Reliability of Eyewitness Identification
Eyewitness identification and other information provided by eyewitnesses to a criminal event are relied on heavily by both law enforcement and courts in the investigative and adjudication stages of the system of justice, yet research indicates that eyewitness testimony is the most unreliable form of evidence and causes more miscarriages of justice than any other method of proof.
Human perception is sloppy and uneven. Existing research does not permit precise conclusions about the overall accuracy of the eyewitness identifications, which are a common feature of criminal prosecutions, but research does lead to the conclusion that identification errors are not infrequent. Eyewitness identifications take place in a social context in which the witness’s own personality and characteristics, along with those of the target observed, are as critical as factors relating to the situation or environment in which the action takes place. Thus, human perception and memory are selective and constructive functions, not exact copies of the event perceived. The gaps will often be filled in by the observer in order to produce a logical and complete sequence of events. Experts distinguish a number of factors that limit a person’s ability to give a complete account of events or to identify people accurately. The following are among those factors:
1. The significance or insignificance of the event
2. The length of the period of observation
3. Lack of ideal conditions
4. Psychological factors internal to the witness
5. The physical condition of the witness
6. Lack of familiarity with members of another race or ethnic group
7. Expectancy
