However, findings from cognitive science strongly suggest that people have little insight into the information they rely on to make decisions.

That is to say, the expert’s mind is a black box — both to the expert and to the trier of fact. This article focuses on black box expertise in the context of forensic examiners who interpret visual pattern evidence (eg fingerprints). The authors review black box expertise through the lens of cognitive scientific research. They then suggest that the black box nature of this expertise strains common law admissibility rules and trial safeguards.Read More
