When Seeing Isn’t Believing: Eyewitness Testimony, Juror Bias, and Wrongful Convictions
Eyewitness testimony has long been regarded as a persuasive form of courtroom
evidence, often swaying jurors even when other forms of proof are inconclusive. However,
psychological research consistently demonstrates that eyewitness memory is not only fallible
but also susceptible to distortion through stress, leading questions, or contextual cues. This
tension between jurors' reliance on eyewitness accounts and the scientific understanding of
their unreliability raises urgent questions about the fairness and accuracy of legal proceedings.
Indeed, wrongful conviction data reveal that eyewitness misidentification is a leading
contributor to miscarriages of justice, underscoring the need for rigorous psychological inquiry
into how jurors evaluate such evidence. The research question guiding this review is: To what
extent does the presence, absence, or discrediting of eyewitness testimony influence jurors’
judgments of guilt in criminal trials?
Psychological Influences on Juror Decision-Making
This review synthesizes scholarship across three interrelated domains. First, it examines
how juror characteristics and implicit biases influence the interpretation of testimonial
evidence, revealing that personal traits and prior experiences often color the evaluation of
credibility. Second, it examines the impact of eyewitness testimony, specifically highlighting how
jurors remain highly responsive to such evidence, even when it is demonstrably flawed. Third, it
examines how contextual variables, like victim identity, intoxication, or third-party evidence,
often exacerbating biases and complicating the deliberation process. Together, these themes
highlight the persistent gap between psychological evidence on memory reliability and the
magnitude of jurors' assignments to it in legal contexts. Grounding this discussion is Loftus's
(1979) theory on the malleability of eyewitness testimony, which demonstrates that jurors often
overvalue eyewitness accounts, even when such testimony is contradicted or discredited. This
theoretical framework serves as the basis for the current experiment, which manipulates the
presence and quality of eyewitness testimony to test its influence on judgments of guilt.
