New articles in press (in Perspectives on Psychological Science) addressing Clark's argument that reforms such as the double-blind lineup, unbiased instructions, and so on can reduce "hit rates". The counterargument is that these "hit rates" that he is concerned aobut are not true hits at all but instead were suggestiveness-induced responses and actually represent ill-gotten gains ...

|DNA to the rescue:
When an innocent suspect is identified by a confident eyewitness as being
the perpetrator of a crime, there may be little to keep that person from
being convicted. Once convicted, there is little hope for later exoneration.
Since the advent of forensic DNA evidence, however, some people who were
mistakenly identified by eyewitnesses and convicted by juries have been
released from prison because the newly-analyzed DNA evidence proved that
they did not commit the offense. Under the aegis of the National
Institute of Justice, a study was made of 28 cases of wrongful conviction.

||In 1996, the American Psychology/Law Society appointed a committee to prepare a white paper reviewing the scientific evidence on eyewitness identification and describing rules for how lineups and photo spreads should be conducted. This paper, authored by Gary Wells, Mark Small, Steve Penrod, Roy Malpass, Sol Fulero, and Elizabeth Brimacombe, was published in the journal Law and Human Behavior in December 1998.

|EYEWITNESSES TO CRIME: THE PHENOMENON OF MISIDENTIFICATION|
Although psychological scientists have been studying human memory for over 100 years, not until the mid 1970's that a focus was directed to eyewitness memory. The importance of such research is easily substantiated because mistaken identification is the largest single cause of false conviction, accounting for more criminal convictions of innocent people than all other causescombined (see Wells, Small, Penrod, Malpass, Fulero, & Brimacombe, 1998).
My eyewitness research program was launched in 1974 while still a graduate
student. It is directed at discovering the causes of mistaken
identification from police lineups and photo spreads with a particular
emphasis on how to prevent these errors. Numerous successful interventions
have been developed, such as:
