We need to fix forensics. But how?

Ten years ago, the National Academy of Sciences (NAS) published a groundbreaking study on the use of forensics in criminal trials. The study found that, in the “pattern matching” fields of forensics in particular, expert witnesses had been vastly overstating the significance and certainty of their analyses. For some fields, such as bite-mark analysis, the study found no scientific research at all to support the central claims of practitioners.
