Eyewitness Error

Eyewitness error is the single greatest cause of wrongful convictions nationwide, playing a role in 72% of convictions overturned through DNA testing.

While eyewitness testimony can be persuasive evidence before a judge or jury, 30 years of strong social science research has proven that eyewitness identification is often unreliable. Research shows that the human mind is not like a tape recorder; we neither record events exactly as we see them, nor recall them like a tape that has been rewound. Instead, witness memory is like any other evidence at a crime scene; it must be preserved carefully and retrieved methodically, or it can be contaminated.

In case after case, DNA has proven what scientists already know — that eyewitness identification is frequently inaccurate. In the wrongful convictions caused by eyewitness error, the circumstances varied, but judges and juries all relied on testimony that could have been more accurate if reforms proven by science had been implemented.
