Brain Fingerprinting 302 WK5 - Essay Example According to Daubert guidelines, new questions would be answered before fingerprints could be entered into evidence. Due to this decision, the court had to introduce five criteria that had to be achieved before evidence could be considered scientific. The first question that must be answered concerns peer review, and sound methodology. The second question involves a known error rate, the third involves testable hypothesis, fourth involves application outside of legal proceedings, and fifth question involves general acceptance (Hensen, 2006). Brain fingerprinting continues to face challenges regarding twins. Twins have the same DNA, but different fingerprints. In addition, the main challenge to brain fingerprinting lies in the fact that there is a lack of universal standards for comparing fingerprints. Several mismatches of partial fingerprints have been encountered (Hensen, 2006). This criterion involves using a particular scientific technique. In other words, it shows the likelihood of being wrong in the case whereby the scientist has asserted that alleged crime has a particular effect. The known potential error should be small, about 1-5 percent (Roth, 2010). This criterion measures the extent at which the actions of the scientist produce results that are scientifically knowledgeable. Appropriate hypothesis testing techniques must be used on questions of interest to the scientific community. The general hypotheses testing techniques must be accepted after undergoing scrutiny by the scientific community (Roth, 2010). The theory must be peer reviewed before publication. The scientist’s peers must scrutinize the work before being published. This is the only ways objectivity of the fingerprinting can be achieved. After publication, the work is then expected to undergo further review by other experts (Roth, 2010). The hypothesis testing method should determine whether the
