Study Notes

Eyewitness Testimony Analysis

Mistaken eyewitness identifications account for 70% of wrongful convictions in the US.
Wrongful convictions have been overturned by post-conviction DNA evidence.
Traditional lineup procedures are often unreliable, due to unconscious cues given by administrators affecting witnesses.
The Innocence Project supports reform procedures to reduce misidentification errors in lineups.

Lineup Procedures

Double-blind procedure: Neither the administrator nor the eyewitness knows which person is the suspect; avoids unintentional cues.
Instructions: Statements to deter witnesses from feeling pressured to choose; prevent feedback cues.
Lineup composition: Fillers (non-suspects) should resemble the suspect description and each other to reduce bias.
Confidence statements: Witnesses state their confidence level immediately after the lineup.
Documentation: Ideally, lineups are recorded electronically; otherwise, audio or written records are required.
