Episode 181 – Fingerprint Analogies

    Fingerprint AnalogiesFingerprint Analogies

Eric Ray and Glenn Langenburg begin the episode with a discussion of an article from a law journal by Barbara Spellman titled, Communicating Forensic Evidence: Lessons from Psychological Science. Among her main points are that statistics, likelihood rations, and random match probabilities are terrible ways of communicating information to juries. She goes on to say that there are a number of misconceptions in latent fingerprint comparisons that must be addressed to juries and that analogies might be a better way to convey information to them. While Glenn and Eric agree and disagree with some of those points, they conclude the episode by reviewing a number of their favorite analogies that they use when testifying or teaching.
