Eyewitness Reliability and Lineup Science
Eyewitness reliability refers to how accurately a witness can recall and identify individuals involved in a crime. Lineup science studies the methods used to present suspects to witnesses, aiming to reduce errors caused by memory flaws or suggestive procedures. Research shows that factors like stress, poor lighting, and biased lineups can lead to mistaken identifications. Improving lineup techniques and understanding memory limitations are crucial for ensuring fair and accurate criminal investigations.

💡 Key Takeaways
- Understand how eyewitness memory can be unreliable due to factors like stress, weapon focus, duration of exposure, and suggestion.
- Explore lineup design elements (sequential vs. simultaneous, fillers, and blind administration) that reduce misidentifications.
- Learn about best practices in lineup procedures to minimize memory contamination, bias, and administrator influence.
- Recognize how confidence, feedback, and post-event information can affect identifications and what investigators should do to obtain reliable results.
❓ Frequently Asked Questions
What does eyewitness reliability mean?
Eyewitness reliability refers to how accurately a witness can recall and identify a person involved in a crime, influenced by memory encoding, stress, attention, exposure duration, lighting, and post-event information.
What is lineup science?
Lineup science studies how to present suspects to witnesses in lineups or photo arrays in ways that minimize misidentifications, using blind administration, proper fillers, and standardized procedures.
What factors affect eyewitness accuracy?
Common factors include stress and weapon focus, viewing conditions (duration, lighting, distance), attention, cross-racial effects, memory decay, and feedback or pressure from investigators.
How can lineups be made fair?
Lineups should be conducted blind or double-blind, use similar-looking fillers, present lineups with sound methodology, provide neutral instructions, and include target-absent options.
What is the difference between sequential and simultaneous lineups?
Simultaneous lineups show all suspects at once; sequential lineups present suspects one by one. Sequential lineups tend to reduce relative judgments and misidentifications.
