Examines the arguments in favor of experimental psychologists testifying as expert witnesses in cases involving eyewitnesses to inform the jury about problems with eyewitness testimony. Rationales for such use are (1) the assertion the jurors cannot discriminate between accurate and inaccurate witnesses, and (2) the assumption that jurors are too willing to believe eyewitness testimony. The present authors point out that known cases of erroneous conviction due to juror overbelief fail to establish that the frequency is unacceptably high. Other studies indicate that jurors are able to take into account at least some factors that influence witness testimony. Contrary to claims made recently by psychologists and lawyers, it is by no means clear that expert psychological testimony about eyewitnesses would improve jurors' ability to evaluate eyewitness testimony. In fact, it is even possible that this sort of expert testimony would have detrimental effects. A hypothetical example of a prosecutor examining a defense psychologist is presented.
