He studies the way people interpret (and sometimes misinterpret) scientific and statistical data and has also written extensively about the use and misuse of DNA evidence.
To separate different DNA fragments, RNA fragments, or different proteins • Different length segments of the DNA, the RFLPs, produced by the restriction endonucleases and amplified by the Koehler argues that the fractional component in the first statistic (0.1 in 100) discouraged jurors from thinking about others who might match by coincidence. Errors in DNA testing occur regularly. Consequently, when discussing the likelihood of a coincidental match it is more helpful to focus on the estimated frequency of the profile than the number of loci or alleles encompassed in
