Ordered questions bias eyewitnesses and jurors

Area of Science:

• Cognitive Psychology
• Legal Psychology

Background:

• Suggestive questioning can distort eyewitness memory and confidence, influencing juror beliefs.
• Prior research indicates that altering question order, even for trivia, can affect perceived accuracy.

Purpose of the Study:

• To investigate if changing the order of questions impacts eyewitnesses' beliefs about their memory accuracy and confidence.
• To determine if jurors' evaluations of eyewitnesses are influenced by these order-induced belief changes.

Main Methods:

• Six experiments were conducted to test the effect of question order on eyewitnesses.
• Participants answered sets of questions presented in varying orders (initially easy vs. difficult).
• Jurors' beliefs about eyewitness accuracy were assessed in relation to eyewitnesses' reported confidence.

Main Results:

• Eyewitnesses reported higher accuracy and confidence when questions initially appeared easy compared to when they appeared difficult.
• Jurors' perceptions of eyewitness accuracy closely aligned with the eyewitnesses' own reported confidence and accuracy beliefs.
• The order of questioning, not just content, demonstrably affects eyewitness metacognition and subsequent juror judgments.

Conclusions:

• Question order is a critical factor influencing eyewitnesses' metacognitive judgments of their memory.
• These findings have significant implications for improving eyewitness questioning procedures in legal settings.
• Understanding the impact of question order is crucial for accurate assessment of eyewitness testimony by both the legal system and jurors.
