Eyewitness Testimony Reliability
Eyewitness testimony reliability refers to how accurately and consistently an individual’s account of an event can be trusted in legal or investigative settings. Human memory is fallible and can be influenced by stress, suggestion, or time, leading to errors or distortions in recall. As a result, eyewitness accounts, while persuasive in court, are not always dependable and may contribute to wrongful convictions if not corroborated by additional evidence.

❓ Frequently Asked Questions
What does eyewitness testimony reliability mean?
It refers to how much you can trust a person’s memory of an event; memory is fallible and can be altered by stress, time, and external influences.

Stress/arousal, duration and visibility of the event, time since the event, distractions, substance use, weapon focus, suggestion or leading questions, and cross-racial recognition biases.
What are common errors seen in eyewitness accounts?
Memory distortions, false memories, misidentifications, and confidence not always matching accuracy, especially after exposure to misleading information.
How can investigators help improve the reliability of eyewitness accounts?
Use nonleading, standardized interviewing methods (e.g., cognitive interviews), conduct double-blind lineups, present items sequentially, avoid feedback, and corroborate with additional evidence.
