What is the CSI effect?

• A. Forensic science fiction has no impact on real trials.
• B. Forensic science-inspired entertainment has caused jurors to have unrealistic and uninformed expectations as a condition for conviction.
• C. A method of evidence collection used at scenes.
• D. A standard for admissibility of fingerprints.

Answer: (B)

Media portrayals of forensic science shape jurors' expectations in real trials. This phenomenon, the CSI effect, describes how crime shows create unrealistic ideas about forensic evidence—think dramatic, near-perfect DNA results, instant lab turnaround, and unwavering certainty. Because jurors expect that level of certainty, they may vote to convict only when such compelling forensic proof is presented or may doubt a case that doesn’t deliver that on-screen certainty. The best understanding is that forensic science-inspired entertainment has caused jurors to have unrealistic and uninformed expectations as a condition for conviction. The other ideas miss the point: it isn’t about a real method of evidence collection, nor a formal admissibility standard, and it isn’t true that fiction has no impact on trials.
