The psychiatric expert in court.
The law about expert evidence is unsatisfactory: it gives scope for the expert to usurp the role of judge, jury and parliament; it brings the professions of the experts into disrepute; and it sets juries the impossible task of sorting pseudo sciences from genuine ones. The law should be reformed by changing statutes which force expert witnesses to testify beyond their science, by taking the provision of expert evidence out of the adversarial context, and by removing from the courts the decision whether a nascent discipline is or is not a science.
