Common questions
What makes forensic science different from ordinary lab science?+
Forensic science applies scientific methods to legal questions and questions of law. The key difference is that the findings must survive cross-examination in court, which is a much higher bar than what ordinary lab science requires. The output needs to be reliable, reproducible, and communicable to a legal audience.
What types of legal cases use forensic science?+
Forensic science applies to criminal, civil, and regulatory proceedings. It is the umbrella term covering all the specialist branches that help answer questions arising in legal disputes.
Why is reproducibility so important in forensic science?+
A forensic finding must be reproducible because another expert might need to verify the same result in court. If a method cannot be repeated or verified by someone else, it won't hold up under cross-examination. The goal is findings that are reliable, repeatable, and clear enough to explain to a court.
